Metrics details
metal allergies are becoming increasingly prevalent
This study examined metal allergy characteristics
and clinical signs associated with patch test results over a 15-year period at the Dental Metal Allergy Clinic of Tokushima University Hospital
A retrospective analysis of 1085 patients revealed that 65.4% tested positive for at least one metal allergen
and cobalt chloride identified as the most common allergens
Female patients were disproportionately affected
accounting for 78.4% of the study population
there was a substantial increase in patients reporting inflammation due to pierced earrings
increasing from 5.0% in 2005 to 43.2% in 2020
Patients with a history of inflammation from earrings had an 81.3% prevalence of metal allergies
which was significantly higher than the 60.4% reported in those without such a history (chi-square test
These findings suggest a strong link between earrings and metal allergies
underscoring the need for improved education
and preventive strategies to address the growing impact of metal allergies on public health
Our retrospective study at Tokushima University Hospital’s Dental Metal Allergy (DMA) clinic over 15 years aimed to analyze patient characteristics
The purpose of this study was to investigate the epidemiology of metal allergies to determine the current situation
identify specific risk factors and symptoms
and develop effective preventive strategies to improve patients’ quality of life
Proportion of clinical symptoms by (a) gender and (b) age
comparisons were conducted via chi-square tests
(b) Prevalence by five-year period; the Kruskal–Wallis test adjusted via the Bonferroni correction was carried out (***p < 0.001
We investigated correlations between the prevalence of metal allergies and several medical history factors
history of inflammation due to pierced earrings
Our study revealed a weak negative correlation (r = − 0.219
p < 0.001) between the prevalence of metal allergies and age
This finding is consistent with our previous results
which suggest a general decrease in positive reactions with increasing age
no significant correlations were detected with other factors
medical history of inflammation due to pierced earrings (r = 0.188
history of rashes induced by jewelry (r = 0.162
While these correlations were not statistically significant and the coefficients suggested a weak relationship
a relatively greater correlation coefficient was found for history of inflammation due to pierced earrings (r = 0.188
Despite its statistical insignificance in terms of broader clinical relevance
this was the highest correlation observed among the factors studied
we decided to further investigate this particular medical history
and prevalence of inflammation due to pierced earrings according to medical history
(b) The percentage of patients with a medical history of inflammation due to pierced earrings
(c) Age distribution according to medical history of inflammation due to pierced earrings
(d) The prevalence of 13 allergens was shown to be greater in patients with a medical history of inflammation due to pierced earrings than in those without such a history
Comparisons were conducted via chi-square tests
Our correlation analysis of patch test reagents revealed significant positive correlations between certain allergens
we found a strong positive correlation between PdCl2 (1%) and NiSO4 (5%) in all patient groups (r = 0.446
in the subgroup of patients with a medical history of inflammation due to pierced earrings
there was a stronger correlation between PdCl2 (1%) and NiSO4 (5%) (r = 0.562
Proportion of patients with positive reactions to palladium and nickel
(a) The percentage of patients who underwent patch tests for both nickel and palladium
(c) The percentage of patients without a medical history of inflammation due to pierced earrings
Data are presented as percentages (numbers of patients)
36 earrings sold on the market and 45 earrings of patients were nondestructively analyzed in regard to their composition using an energy-dispersive X-ray fluorescence EDX-900 spectrometer (Shimazu Corporation
The earrings on the market contained high concentrations and frequencies of copper
patients who used nickel-containing earrings had stronger positive reactions to nickel in patch tests than did patients who used earrings containing less nickel
We were unable to assess the release amount
but we did find a clear relationship between the positive metal elements in patients’ patch tests and the composition of the pierced earrings
This strongly suggests a substantial risk associated with wearing pierced earrings
This study emphasizes the importance of regulatory measures in mitigating the risk of metal allergies
In parallel with successful regulations on nickel exposure in the EU
Japan could benefit from similar interventions
Introducing comparable regulations or labeling requirements could significantly reduce the risk of metal allergies
particularly those related to pierced earrings
and serve as a preventive strategy before clinical intervention becomes necessary
Palladium is congener to nickel and may also be a high-risk metallic element similar to nickel
The presence of oral lichen planus/oral lichenoid lesions in older patients is another noteworthy finding in our study
These conditions are likely related to long-term exposure to metals used in dental restorations
Frequent contact with metals in the oral cavity
particularly in patients with multiple metal restorations
Future studies should investigate the relationship between metal exposure from dental restorations and the onset of oral lichen planus and related lesions
the proportion of palmoplantar pustulosis/dyshidrotic eczema cases peaked in the 50s
Since palmoplantar pustulosis/dyshidrotic eczema is diagnosed separately from psoriasis in Japan
the proportion of cases may differ from that reported in other countries
some patients developed palmoplantar pustulosis from dyshidrotic eczema; therefore
they were classified into the same category as palmoplantar pustulosis/dyshidrotic eczema
The difference in age distribution between oral lichen planus/oral lichenoid lesions and palmoplantar pustulosis/dyshidrotic eczema suggests distinct underlying mechanisms of these conditions
although further research is needed to clarify the pathophysiology
The findings of our study have important public health implications
particularly with respect to the prevention and management of metal allergies
The high prevalence of metal allergies related to pierced earrings underscores the need for public education on the risks associated with wearing metal jewelry
Public awareness campaigns could inform individuals about the potential for allergic reactions
which are commonly used in inexpensive jewelry
the implementation of regulations to limit the release of allergenic metals from jewelry
could significantly reduce the incidence of metal allergies in other countries
Such regulatory measures could serve as important preventive strategies
reducing the need for clinical interventions and improving the quality of life for individuals at risk of developing metal allergies
the reliance on patient self-reports for some of the data introduces the potential for recall bias
affecting the accuracy and reliability of the findings
Such errors in information or distortions in memory within self-reports can significantly affect the reliability of the study
The single-institution design and the potential lack of representativeness of the patient cohort in relation to the broader Japanese demographic could limit the generalizability of these findings
Owing to being confined to a specific patient cohort and a particular timeframe
the applicability of these findings to broader contexts
especially those with diverse cultural or socioeconomic characteristics
caution should be exercised when extending these results to different geographic regions or demographic subsets
this study may have restricted information on patient history and diagnosis and may have lacked comprehensive data on other influential factors
This gap necessitates more expansive studies to explore these associations in greater detail
Another inherent limitation of retrospective studies is the difficulty in capturing changes in a patient’s disease progression
Because the data represent snapshots at specific time points
information about subsequent pathological changes may be incomplete
a careful approach is required in interpreting and generalizing the results
involving larger and more diverse patient populations
are essential to increase the reliability and applicability of these findings
This study clearly demonstrates the need for ongoing research
particularly in understanding the pathophysiology of metal allergies
Future research could explore the genetic basis of metal sensitization
the role of environmental factors in allergy development
and the long-term health impacts of chronic exposure to allergenic metals
Such studies could pave the way for innovative approaches in allergy prevention and treatment
We would like to conduct a prospective cohort study to track the development of metal allergies over time in various populations
This approach will provide more precise data on the progression of these allergies and their triggers
our study highlights the increasing prevalence of metal allergies in Japan
particularly among females with a medical history of inflammation caused by pierced earrings
The high prevalence of allergies to nickel
and other metals underscores the need for public health interventions
including regulatory measures and public awareness campaigns
Future research should focus on understanding the genetic and environmental factors that contribute to metal sensitization
as well as investigating new approaches to prevention and treatment
By addressing the growing burden of metal allergies
we can improve the quality of life for affected individuals and reduce the long-term health impacts of these conditions
The study adhered to the tenets of the Declaration of Helsinki and received approval from the Ethics Committee of Tokushima University Hospital (protocol code 1036)
Informed consent was obtained from all the subjects involved in the study
The correlations between the incidence of metal allergies and various factors
were analyzed via Spearman’s rank correlation coefficient
the correlation between different allergens was assessed using the same statistical method

Nishi-Awa Tourism Association Sora-no-sato
Tokushima is famous for indigo plants and dye
but there is also a traditional form of dyeing that uses a much rarer plant called akane
This precious coloring agent was used in ancient times to create a deep red color
which was used in the flags and banners of feudal families and even the red center of the Japanese flag

is seeking to liven up its Awa Odori dance festival amid the inbound tourism boom partly by addressing a shortage of accommodation
The summer spectacle in Tokushima draws well over a million spectators to the area but the effect on the local economy has been rather limited due to the scarcity of hotels
The traditional folk dance festival started Sunday and will last until Thursday amid caution following the country's first-ever advisory on a potential megaquake in the Nankai Trough
Organizers took steps such as informing the public on where to evacuate in the event of a massive quake
the festival was hit by a controversy involving premium seats
Elevated seats priced at 200,000 yen ($1,360) per person
but they were later found to have violated the building standards law
The number of guest rooms in hotels and inns in Tokushima stood at around 4,000 as of Aug
"Guests staying overnight within the city are usually on business trips," said Shinichiro Okamoto
Awa Odori spectators tend to stay in Takamatsu in the neighboring Kagawa Prefecture where hotels and inns are concentrated
the prefectural government has launched a subsidy program to promote the construction of four-star hotels
With Japan expecting to see a record 35 million foreign visitors in 2024
the Tokushima prefectural and city governments are also hoping to lure more tourists through new events
Mickey Mouse and other characters from the Tokyo Disney Resort will join a special parade around JR Tokushima Station during an Awa Odori event to be organized by the prefectural government
Government surveys showed Tokushima Prefecture ranked at 46th among the country's 47 prefectures in terms of the number of guest rooms at accommodation facilities in fiscal 2022
It was also 46th in the number of overnight stays in 2023
we want visitors to know the charm of Tokushima
encourage them to come back," a senior prefectural official said

Tokushima Prefecture—Anan city officials announced on Jan
19 that the oldest trace of “shinsha" (cinnabar) mining in Japan was found at the Wakasugiyama cinnabar mining site here
Experts theorized that it is possible that the world standard mining technology of the time was introduced at the site more than 1,400 years earlier than believed
The location is known as a mining site of cinnabar
The trace found suggests that a mining technique using fire was used during the late Yayoi Pottery Cultural Period (1000 B.C.-A.D
The technique is called the “fire-placement method,” which was utilized in ancient Rome and China's Han Dynasty
the surface of a hard rock is heated by burning sapwood to make it brittle before mining
the oldest known example of this method is believed to have been used at the Nobesawa silver mine site in Yamagata Prefecture in the early Edo Period (1603-1867)
According to the city government’s cultural promotion division
during excavations that began in fiscal 2023
a pit approximately 40 centimeters wide and 50 cm deep was discovered in the sedimentary rock’s bedrock
Since it was artificially dug along the vein and black soot remained on the wall
it was determined that there was a high probability that it was the remnants of mining using the fire-placement method
a professor of archeology at Tokushima Bunri University
there are documents that indicate that ancient Rome used similar techniques for mining gold and the Han Dynasty used similar methods for mining cinnabar
“It is important to note that world-class mining technology was brought to Japan during the Yayoi Period," Okubo said
"It is possible that the latest technology from China was introduced to Shikoku via Kyushu and the Seto Inland Sea.”
Vermilion was considered a symbol of power and in ancient times was painted on the faces of the dead
and in the stone chambers of ancient tombs
In the third-century Chinese history book called “Gishiwajinden,” it is written that cinnabar was harvested in the mountains of Japan
and that Queen Himiko offered cinnabar to the Chinese dynasty

Tokushima — “A world first drives in this town,” reads a banner at the Awakainan Bunkamura cultural complex in Kaiyo
The town is the starting point of a transport service that uses dual-mode vehicles (DMVs)
which can run on both roads and railway tracks
By Kota Arakawa / Yomiuri Shimbun Staff Writer
The world’s first full-scale commercial operation of DMVs was achieved in the town by Asa Coast Railway Co
The company operates DMVs converted from microbuses
Wadaiko drum music played on board while the steel wheels used on the tracks were lowered
and I could feel the front of the vehicle slowly rising
The DMV ran on the tracks via Kaifu Station and reached the coastline
passengers admired the breathtaking view of the sea from the windows
This is the favorite view for Kazuhiko Kochi
a 51-year-old official of Asa Coast Railway
The vehicle then entered Kochi Prefecture before completing its approximately 10-kilometer railroad journey to Kannoura Station
where it switched back to bus mode to drive on a national highway
After making a stop at Uminoeki Toyo Town Station
the vehicle re-entered Tokushima Prefecture to reach its final stop
“I was able to appreciate the views of the sea and mountains
which makes this vehicle one of a kind,” said a 54-year-old man from Komatsushima
“I hope more and more people will use it.”
Asa Coast Railway is a joint public and private venture funded by Tokushima and Kochi prefectures as well as the two towns along the route
Its railway services started in 1992 as the Asato Line
running between Kaifu and Kannoura stations
The now defunct Japanese National Railways originally planned railroad construction for that stretch
but the plan was aborted and subsequently taken over by Asa Coast Railway
DMV driver Kochi was employed by the company in 1993 and started working as a train driver
Asato Line trains were filled with the lively conversations of high school students on their commute to school
the Tokushima prefectural Shishikui Business High School closed
causing a decrease in users of Shishikui Station
The number of Asato Line passengers declined and the company’s business fell into the red
Then he heard that DMVs would be introduced
Yet commercial operations of DMVs posed a host of unprecedented problems
Even though existing facilities and equipment could be used
the company had to revamp and upgrade them
such as building new lower platforms suitable for the height of the vehicles
The company was also required to obtain various permissions and approvals regarding bus operations from the central government and prepare a dedicated system for operations and security
Drivers had to obtain a bus driver’s license
DMV services were finally launched in December 2021

The spring whirlpool viewing season has begun in the Naruto Strait in Tokushima Prefecture
The "whirlpool opening" is held every year by Naruto City and the Tourism Association on the day of the spring tide
a Shinto ritual was held on a boat with the participation of tourism ambassadors from Naruto City in Tokushima Prefecture and Awaji Island in Hyogo Prefecture
who prayed for safety at sea and the promotion of tourism
are created by the ebb and flow of currents in Naruto Strait and vortexes can reach up to 20 meters in diameter
swirling at a velocity of 20 kilometers per hour
It's also pretty cool viewing from the observation deck on the lower level of the bridge above the whirlpool
Kinda strange vibe inside the steel underbelly
hearing and feeling the roaring traffic passing above
and seeing the water and rocky shoreline so far below
I imagine it was quite a feat to build that suspension bridge between Awaji and Shikoku
with the swirling currents of the whirlpool around the foot of the south tower
on the north side of Awaji is pretty impressive
It was a 2 meter waterfall about 5 meters wide after heavy rain
The whirlpool was gentle and I swam towards the waterfall
It pulled me down and kept pushing me down
Finally after 3-4 seconds I was pushed away from the water and I felt like being in a washing machine
Anything to make a Buck this too close to my comfort as the center could shift rapidly
The best place to view a Whirlpool is from the safety of Dry Land and NOT on a Boat with NO life Jackets
That boat could easily get sucked into the rotating currents and capsize

Vox Populi
Vox Dei is a daily column that runs on Page 1 of The Asahi Shimbun
I have been asking myself this question since I read an Asahi Shimbun story about the Tokushima Modern Art Museum’s announcement that an oil painting in its possession
believed to have been by French artist Jean Metzinger (1883-1956)
the painting came with a certificate of authenticity when the museum purchased it 26 years ago
But suspicions began to arise last year that this could have been forged by Wolfgang Beltracchi
a German artist dubbed the “legendary master forger.”
When a colleague of mine interviewed him at his studio in Switzerland
Beltracchi readily owned up to the deception
But he had apparently worked really hard to strive for perfection
Beltracchi researched the artist’s diary and created a device for aging his painting artificially
Beltracchi’s forgery was not a “copy of the original,” but an original work of his own in Metzinger’s style
I am utterly in awe of Beltracchi’s talent
I must admit that when I visit art museums
I sometimes check the names of the artists before I look at the paintings
I imagine some visitors read the museum panel next to the forgery and were truly impressed by the painter’s “characteristically lively style,” never doubting for a moment that this was actually someone else’s work
the value of a work of art must be intrinsic
what changed between before and after the discovery of the forgery
even Michaelangelo was once guilty of it in his youth: He made a marble sculpture of Cupid
I’m sure the whole world would just love to look at it now
and the museum is reportedly considering exhibiting it again

TOKUSHIMA — The gondolas on a ropeway connecting the foot and the summit of Mt
Bizan in western Tokushima City were recently replaced with brand new ones
The Bizan Ropeway will reopen with the new gondolas on March 30
having been suspended for renewal since January
The new gondolas have larger windows so that passengers can enjoy a feeling of openness
Tokushima is famous for its Awaodori group dancing festival
a tourist facility where visitors can see and experience Awaodori dance in its birthplace
The floor space per passenger is about 60% greater than before and the windows are about 40% taller
There will also be performances of Awaodori dance and Awa Ningyo Joruri
“I hope residents and tourists will ride the new gondolas and thoroughly enjoy the view.”
The third-generation gondolas had been in service for 25 years and had become too aged to continue
Two art museums in Shikoku might be the victims of a master forger
The Tokushima Modern Art Museum in Tokushima announced on July 12 that an oil painting believed to be a work by French painter Jean Metzinger (1883-1956) is suspected to be a fake
the work is titled “At the Cycle-Race Track.” It is 55 centimeters tall and 46 centimeters wide
The museum stopped exhibiting the painting at the Kyoto City Kyocera Museum of Art
and it is investigating whether the painting is genuine or not
an art movement launched in France by Pablo Picasso and others in the early 20th century
“At the Cycle-Race Track” is considered one of Metzinger’s outstanding works from early in his career
and it is believed that the piece was painted from 1911 to 1912
The Tokushima museum purchased the painting for ¥67.2 million via mediation by an Osaka gallery in 1999
The museum has exhibited the painting about 40 times
It has also lent the painting to other art museums nationwide
including the National Museum of Western Art in Tokyo
the museum obtained information from a person in the art world saying that there is an article on the internet claiming the painting is a fake
Then museum officials found an article noting that the painting was produced by Wolfgang Beltracchi
It is said that he raked in billions of yen by forging paintings of famous painters’ works
Although officials at the museum said that the online article was written more than 10 years ago and the validity of the content is unclear
they asked the seller and art-related organizations that make catalogs of Metzinger’s works to provide information as part of its investigation into the issue
The painting was being displayed in a Cubism exhibition at the Kyoto City Kyocera Museum of Art from March 20
but the Tokushima museum pulled the painting on June 17
Although the museum had planned to show the painting as a notable artwork in an exhibition from its collection that was scheduled to start on July 27
“We will collect information broadly and want to confirm whether it is fake or not as soon as possible,” a museum official said
Kochi announced on July 12 that it is investigating whether an oil painting in its collection is a fake
The work in question is “Girl with Swan” by German painter Heinrich Campendonk
The museum said it purchased the painting from a gallery in Nagoya in 1996
The Tokushima Modern Art Museum confirmed that a work in its collection was on an online list of artworks forged by Beltracchi
and since “Girl with Swan” was also on the list
“Girl with Swan” is believed to have been painted in 1919
The Kochi museum has lent the painting to other art museums nationwide and exhibited it in its exhibition to commemorate the 30th anniversary of its opening
Museum officials believe it is highly possible the painting is a fake
It will conduct a probe into the gallery from which it bought the painting and analyze materials used in the paints
The museum said it will announce the result around autumn this year

TOKUSHIMA — More and more broccoli is coming out of Tokushima Prefecture
That’s the fifth largest volume for a prefecture and seven times more than in 1989
By Hiroki Kitano / Yomiuri Shimbun Staff Writer
Broccoli is set to be listed in fiscal 2026 as one of the Agriculture
Forestry and Fisheries Ministry’s “designated vegetables,” or those vegetables consumed in mass quantities and important for daily life
local producers are working to expand production and create new products
and 157,100 tons of the vegetable were shipped nationwide in 2022
While other major vegetables have seen their harvest sizes fall or stay level over the past 30 years
the agriculture ministry indicated it would add broccoli to its list of 14 designated vegetables
which includes cabbages and daikon radishes
Broccoli will be the first addition in 50 years
The ministry provides substantial subsidies to producers of designated vegetables if there is a price slump and helps to ensure a stable supply
“[Broccoli’s] growing popularity is due to various factors
and its ease of consumption,” the ministry said
The shipment volume and cultivation area for broccoli in Tokushima Prefecture have risen every year since 1989
only 1,513 tons were shipped and there were 185 hectares under cultivation
while there are now 974 hectares set aside for broccoli
Local producers have been racking their brains for ways to make the most of the demand tailwind
now a part of the prefecture’s cooperative
has been taking advantage of the ease with which broccoli can be grown compared to other leafy vegetables and the ease with which beginners can grow it
and producers of the vegetable doubled from 155 in 2008 to 320 in 2018
with shipment volume rising by around 300%
Broccoli has become the highest selling product in the area
and the area has seen some of the prefecture’s strongest sales growth
a 32-year-old former employee of a welfare facility
started farming in 2021 and is now growing six kinds of vegetables
He is also trying his hand at broccoli and shipped 1.2 tons of it for the first time this year
“It was easy to cultivate because there was little damage by pests
I want to improve my skills further and boost productivity,” Ishihara said
a branch of the cooperative created a 3-meter-tall statue of the broccoli with a 3D printer
It then installed the statue in front of its building
we are working with the Itano district and surrounding areas,” a representative for the branch said
“We hope to create a [favorable] environment and work more on promotion.”
Nikky Farm in Tokushima City has expanded broccoli plantings to cover 35 hectares
It ships broccoli mainly to the Kansai region
“I feel that Tokushima is famous for broccoli in Kansai because we hold the top market share there,” said company President Mitsutoshi Niki
which are often thrown out during processing
The snack is set to go on sale at Kansai supermarkets in July
“I think the stalks are too delicious to waste,” said Niki
“I hope to come up with a lot of different ways to bring them to market.”
National Report
TOKUSHIMA—David Moreton has for years served as a messenger of the cultural appeal of a Buddhist pilgrimage of 88 temples across the island of Shikoku
Moreton has researched the tradition for 26 years
partly as an associate professor at Tokushima University
and guided foreign visitors along the route
The 56-year-old has long been engaged in the translation of “Shikoku Japan 88 Route Guide,” known as a must-have English-language guidebook
obtained Japanese citizenship and took on the Japanese name Joji 12 years ago
One means “always” and the other “cherish.”
The 1,400-kilometer route connects sacred sites associated with Kukai (774-835)
the monk who founded the Shingon sect of Buddhism and is known posthumously as Kobo Daishi
Moreton said he was particularly attracted by the custom known as “osettai” (hospitality) of residents providing pilgrims with food and beverages as well as giving them a ride when needed
A similar custom exists along the Camino de Santiago
a pilgrimage route to the cathedral of Santiago de Compostela in Spain
“The osettai of the Shikoku pilgrimage is based on faith in Kobo Daishi
and residents equate pilgrims to the grand master of Buddhist teaching,” he said
Moreton always tries to explain the weight of the pilgrimage’s history to foreign visitors and sometimes shows historical materials he has gathered over the years of research
The collection includes a white robe worn by Alfred Bohner (1894-1958)
one of the first non-Japanese who embarked on the pilgrimage and made its attractions known in Europe
who served as a professor at what is now Ehime University
“Two on a Pilgrimage: The 88 Holy Places of Shikoku,” in his native language in 1931
Moreton became acquainted with Bohner’s eldest daughter through a Swiss couple he met in Tokushima while they were on the pilgrimage
When she passed away at the age of 93 in 2016
relatives entrusted him with Bohner’s personal effects in the hope that he would hand down the forerunner’s story
a box to store votive tablets and a string of beads were among the items
The white robe is covered by red seals its owner received at the temples he visited along the way
“This is probably one of the oldest historical materials that bear testimony to the history of foreign pilgrims.”
Some relatives of Bohner and Moreton had less pleasant associations with Japan
Bohner’s elder brother was captured by Japanese during World War I and placed in the Bando prisoner-of-war camp in Naruto
Moreton’s grandfather was taken as a POW by Japan and mobilized for construction of a railway between Thailand and Burma
Moreton became manager of the Tourism Strategies Office and Planning Department of Air Travel Tokushima Inc.
“I wanted to share more attractions of the Shikoku pilgrimage and Tokushima with non-Japanese,” said Moreton
who lives in the capital of Tokushima Prefecture
Moreton is determined to carry on Bohner’s journey

a 26-year-old Mongolian who has fallen for the town of Otsuchi in Iwate Prefecture
has always preferred rural areas over city centers
she was considered a perfect fit for the central government’s “local vitalization cooperator” program
relocate to rural areas and engage in community vitalization work on commission from the hosting local government
But foreign workers like Ariungerel are becoming more in demand for the program due to the influx of tourists and non-Japanese residents in rural regions
Ariungerel’s main job is working at an intensive care home for elderly people in the Kirikiri district of this northeastern town
recently asked one of the residents at the care home
“I initially had a hard time because I didn’t understand the dialect here,” Ari said
‘enryo’ (which can mean ‘restraint’ or ‘refraining from doing something’) is a likable word that has no parallel in other countries.”
Ari came to Japan in September 2018 under the “specified skilled worker” visa system
She obtained a certified care worker license while working at a nursing home in the prefectural capital of Saitama
She changed jobs and joined the care home in Otsuchi in spring 2023 through the introduction of a friend of a relative
“I did so because I like the countryside better than a city,” Ari said
as Otsuchi’s local vitalization cooperator
serves as a life coordinator for non-Japanese workers in the town
She and a fellow cooperator from Mongolia accompany foreign nationals to hospitals or the town hall
Ari has helped three people who came to Otsuchi from Myanmar in autumn for nursing care work
She has danced a local folk dance at a summer festival here and has also joined community gatherings
Ari said she wishes to remain in Otsuchi even after her term as local vitalization cooperator ends
I hope to be teaching what I have learned myself
to others who come to live in Japan,” she said
chief director of the Tsutsumi Fukushikai social welfare corporation
was the one who proposed to the Otsuchi town government that it appoint Ari and others as local vitalization cooperators
“Businesses in the welfare industry are scrambling for non-Japanese workers,” Haga
“Things are particularly tough in depopulated areas
More foreigners will settle down here only if we create an environment that makes it easier for them to live here
We aspire to be a model for what a nursing home should be like in an aging
About 150 local vitalization cooperators across Japan were non-Japanese in fiscal 2022
Their duties are typically related to tourism and disseminating information
must be a resident of an urban area who is moving to a rural area
Those who have served as assistant language teachers in Japan qualify to be local vitalization cooperators
even if they are moving from one rural area to another
a Canadian in her 30s who lives in Tokushima Prefecture
Johnson came to Japan in summer 2017 and served as an assistant English teacher at elementary and junior high schools in Sanagochi
She said she was surprised by the landscapes of the village
located in a mountainous area on the main island of Shikoku
“I didn’t even know Shikoku’s presence until I came here to start my job,” Johnson said
which is quite different from the sharp feel of the Rocky Mountains.”
Johnson has been an employee of the Tokushima prefectural government since 2021
Her activities are based in the western part of the prefecture
Johnson has been posting her photos and videos
typically taken at tourist spots in the region
They include mountainous areas with a view of the Yoshinogawa river
Her posts are targeted at inbound visitors and are accompanied by English-language commentaries
“I like the natural settings here,” she said
“I also like interacting with regional communities here.”
Johnson has guided inspection tours for overseas travel agencies and other parties
including at a government-designated roadside rest area
for an audience of both residents and tourists
Tokushima is the only prefecture with a local vitalization cooperator program open exclusively to foreign residents
The prefecture has hired new cooperators under the program every year since fiscal 2021
The internal affairs ministry hopes to sharply increase the number of cooperators across Japan
It took account of Tokushima Prefecture’s measures when it introduced a system in fiscal 2024 to support efforts for recruiting foreign local vitalization cooperators
which was prolonged as an exception because of the novel coronavirus pandemic
that she wishes to remain in Tokushima Prefecture after that deadline because her period of stay in Japan has been extended
Johnson watched “Sailor Moon,” the popular anime series
in the original Japanese when she was very young
and she studied Japanese at a university in Canada
She can communicate smoothly with local residents
Johnson said she believes foreign cooperators will find it difficult to interact with regional communities if they are not proficient in Japanese

TOKUSHIMA — The Tokushima Modern Art Museum has confirmed that its oil painting “At the Cycle-Race Track” is a forgery by Wolfgang Beltracchi
By Kota Arakawa / Yomiuri Shimbun Staff Writer
The museum originally believed the painting to be by French artist Jean Metzinger (1883-1956) and purchased it for ¥67.2 million from a now-closed Osaka gallery in 1999
based on a faulty certificate of authenticity and information provided by the German police
the museum has now definitively identified the work as a forgery
the museum said Tuesday it is considering seeking a full refund of the ¥67.2 million from the painting’s seller
The investigation into the painting’s authenticity began in June after the museum received information suggesting that Beltracchi was the likely artist
it contacted the artist’s copyright management organization in France
the group responded that the certificate of authenticity was invalid
Beltracchi himself admitted to The Yomiuri Shimbun that he painted the artwork
An investigator in charge of investigating Beltracchi in 2010 and 2011 at the Berlin Police was also contacted via email from August
The museum learned that the oil painting’s original owner was a German art dealer convicted of being Beltracchi’s accomplice
the person who initially produced the certificate of authenticity confirmed the painting was inauthentic
the museum has concluded the painting is a forgery
It intends to have the painting undergo scientific analysis
“I sincerely apologize for the concern and inconvenience caused to the residents of the prefecture and all those who admired the painting,” said museum director Yoko Tojo at a press conference
Museum official Toshio Takeuchi said the museum plans to put the painting on display
“We want to give the residents of the prefecture an opportunity to view the work
Kochi announced on March 14 that “Girl with Swan” is now believed to be another forgery by Beltracchi

A local council in Tokushima set a record when it raised the prefecture's hourly pay from the current 896 yen ($6.18) to 980 yen in this fiscal year’s minimum wage revision
What seems like small change could greatly benefit workers
all prefectures have finalized their rates
Japan’s national weighted average minimum wage for fiscal 2024 increased by a record 51 yen
Amid rising prices and competition for talent due to labor shortages
27 of 47 prefectures exceeded the wage increase guideline set by the central government
This annual figure is determined via the labor ministry’s central council dividing prefectures into three ranks
based on their economic circumstances and providing a corresponding amount to increase the minimum wage by
Local councils in each prefecture then adjust the minimum wage accordingly
Tokyo has the highest hourly pay of this year's revisions at 1,163 yen while Akita Prefecture is at the bottom of the list at 951 yen
The gap between the top and the bottom of the list has narrowed slightly from 220 yen to 212 yen
The guidelines for fiscal 2024 suggested a uniform increase of 50 yen
which would have brought the national average to 1,054 yen
many prefectures chose to increase pay by more than the proposed 50-yen raise and bumped the final average to 1,055 yen
The number of prefectures with a minimum wage exceeding 1,000 yen has increased to 16
Tokushima Prefecture had the second-lowest minimum wage in the country
“It was necessary to set a minimum wage appropriate for Tokushima Prefecture’s position when compared with other prefectures based on various economic indicators.”
“Tokushima Prefecture is ranked above the middle compared to all other prefectures.”
The local council took the current national median minimum wage of 930 yen and decided to add the labor ministry's suggested 50 yen to that amount when revising the hourly rate
9 yen was the most any prefecture had added to a guideline
Tokushima Prefecture smashed this by adding 34 yen and boosting its national rank to 27th
the prefecture's minimum wage increased by nearly 10 percent
Aichi and Osaka stuck to the 50-yen guideline when adjusting their pay rates

TOKUSHIMA—Insects are no longer on the menu here after an edible cricket supplier ceased operations and declared bankruptcy
The announcement of Gryllus Inc.’s insolvency was made by the Tokushima arm of Tokyo Shoko Research Ltd
and Teikoku Databank Ltd.’s Tokushima branch on Nov
The startup from Tokushima University specialized in the production and processing of crickets for human consumption
Gryllus decided to file for bankruptcy with the Tokushima District Court amid financial struggles after criticism spread—mostly online—over pushing crickets as food in Japan
7 with liabilities totaling 153 million yen ($1 million)
According to Tokyo Shoko Research and other sources
Gryllus was founded in 2019 to mass-produce edible crickets at a former elementary school building in Mima
The idea of eating insects was then drawing considerable attention as a way to alleviate food shortages throughout the world
Gryllus pitched a cricket-based “senbei” cracker to Muji grocery chain’s outlets in 2020
Working with a major convenience store operator
Gryllus also released a corn snack with cricket powder in 2022
Gryllus joined hands with Nippon Telegraph and Telephone East Corp
(NTT East) and embarked on trials to develop an effective method of raising crickets for food
The test closed toward the end of that year
Gryllus was struggling to make a series of capital investments
Despite achieving record-high sales of 38 million yen
the corporation logged a loss of 339.2 million yen for the fiscal year that ended in May 2023
The company never broke its streak of annual deficits since its establishment four years prior
Gryllus came under fire on social media following news reports on its distribution of school lunches containing cricket powder at a high school in Tokushima Prefecture
Critics flooded Gryllus with complaints even though those lunches were exclusively served to those who chose them
Students unwilling to dine on bug-infused food
A succession of future plans to market cricket-based products nationwide were then dropped
Gryllus is said to have been left with a large amount of inventory during that time
and the company shut down its Mima production facility at the end of last year as part of its efforts
It also cut down its 50-person workforce in phases
Although it developed a new business plan and applied to the central government for a subsidy
forcing Gryllus to give up on any efforts to continue business

is asking for a refund after confirming that what it believed to be a century-old modern art masterpiece in its collection is a forgery
prefectural officials announced that “Girl with Swan,” long attributed to German expressionist Heinrich Campendonk (1889-1957)
has been confirmed to have been painted by a master forger
The prefecture will seek a refund from the art dealer in Nagoya that sold the painting to the museum in 1996 for 18 million yen ($121,000)
The announcement follows an expert investigation into the oil painting
which was prompted by a source alerting the museum in June to concerns about the artwork's authenticity
Officials said the painting was likely forged by German artist Wolfgang Beltracchi
known for his mastery in counterfeiting works of famous artists
who served time in prison for his art deceptions
has confirmed to The Asahi Shimbun that he painted the picture that was sold to the Kochi museum
owned by a museum in neighboring Tokushima Prefecture
Tokushima officials have launched their own investigation into the artwork

Kochi officials cited a titanium white pigment likely used in the artwork
Officials said the painting has a label on its back showing its provenance
which is also believed to have been fabricated by Beltracchi
the painting and its image appear on the German police list of artworks forged by Beltracchi
officials pledged steps to prevent a recurrence
including more thorough research on artworks prior to purchase
some still appreciate the painting’s value as an artwork
In light of the public notoriety generated by recent reports
officials are considering re-exhibiting the painting
accompanied by notes on its history and context

instead of a huge box that sits on the site
junya ishigami‘s winning competition entry for the culture and arts hall in tokushima is characterized by a series of terraces
in connection with the tokushima central park
which is located adjacent to the site and houses the ruins of tokushima castle
the form of the terraces resembles petals dancing in the air
this composition is also reminiscent of the procession of awa odori
which takes place in tokushima prefecture every august
the japanese architecture studio has come up with a proposal that aims to open the hall to the city and its people
making it a place where they can spend a lot of time
relax and enjoy their day and the performances on view
since the entire facility is made up of a collection of terraces
neither the large halls nor the small halls or other functions have a clear outline.‘public buildings in the future
need to be able to flexibly change their roles and usage in the event of various events that may strike suddenly,’ notes ishigami in the project’s description
a terrace that floats in the air can also be used as an evacuation plaza
under the current conditions of widespread infection
outdoor / semi-outdoor terraces and well-ventilated indoors are key
we aim to be able to adapt to various situations.’

in contrast to typical concert hall designs
where the space is formed by uniform seats that are packed in a box and look in one direction all at once
the interior of this main hall is made up of petal-like platforms that attribute a unique personality to it
these can serve different purposes when a performance is not taking place
each foyer can be made into an independent space
the facility’s small hall is planned as open to the city and to the site’s landscape
with a transparent glass wall that softly wraps the space
the audience seats here are constructed based on the style of the ancient amphitheater
the project also includes a series of other functions
a semi-underground multipurpose studio and various foyers and gardens

‘while product designers can easily experiment on a 1:1 scale
architects work on a much abstract level and imaginary scale,’ the japanese architect says when asked about his perception of scale and transparency during our interview
‘as an architect with scale models I expand or reduce the actual scale and can be much more flexible than a product designer
making new borders in architecture can sometimes mean “transparent” but also very thick
that is when the surrounding creates its own space
that was usually stays invisible is also an interesting perception of space
that is what I tried to do in the ‘chateau la coste’ installation at the venice biennale 2010
or another distortion in perception was shown in kortrijk in the ‘picnic’ installation at interieur 2010
serially produced products form a society… get alive
a more comfortable environment is needed.’ see more images of ishigami’s culture and arts hall in tokushima below

The Yoshinogawa racecourse features 12 obstacles, including an about 4-meter-high wall and a rope swing, placed along a 100-meter course. The sport will be officially adopted as a modern pentathlon event at the 2028 Los Angeles Olympics. In Japan, the Japan Obstacle Sports Association will oversee the sport.
While the association was aiming to build a course that met international standards, the chairman of a construction company in Yoshinogawa invested in and built the course. The Yoshinogawa course was completed in April.
The first competition attracted about 3,000 people, and about 20 hotels in the city were nearly fully booked. The city government wanted to support the project and provided such assistance as sending its employees to the competition as staff.
The 1st Japanese Championships in Obstacle Course Racing were held in October, and about 80 people from Japan and overseas tried to clear the 12 obstacles.
A city official said they hoped Yoshinogawa would produce an Olympic athlete.

which has been suffering a long slump in business
is moving ahead with the demolition of its old wooden station buildings and replacing them with simpler ones that look more like bus stops
By Hiroki Kitano and Jo Ishibuchi / Yomiuri Shimbun Staff Writers
the company has already constructed 13 such stations so far
Some residents have voiced opposition to the demolition of the old station buildings
which have served as local landmarks and provided travelers with a sense of being on a journey
a station building from 1936 was demolished and replaced with a new aluminum structure at Chuden Station in Komatsushima
The station on the Mugi Line now has a space measuring only 10.8 square meters and is equipped with just two benches and a ticket vending machine
The daily number of passengers using the station was 826 on average last fiscal year
and it is mostly used in the mornings and evenings by students and others commuting to school or work
An 18-year-old high school girl who uses the station to get to school spoke of the inconvenience of the small station
“It can’t accommodate all of us on rainy days
so lots of people stand outside with umbrellas while waiting for the train,” she said
JR Shikoku is facing a difficult situation
Railroad transportation revenue peaked at ¥37.065 billion in fiscal 1991 and declined continuously since then
The company has not been profitable since 1987
when the former Japanese National Railways was split and privatized to create it
The railway has worked to streamline operations by reducing personnel costs
including making 86% of stations unmanned and implementing one-person operation for about 60% of regular trains
Simplifying station buildings began in fiscal 2014
Large-scale repairs to stations cost several million yen and
Because station buildings have served as the “face of the community,” opposition has grown among local residents
JR Shikoku was planning to simplify Awa-Kamo Station in Higashi-Miyoshi
The station is known for its Western-style building that has a triangular roof
When the company informed the local government of its intention in January 2022
residents launched a petition drive against the move
They claimed that simplifying the station could make the entryway to the town desolate and lifeless
so they submitted 850 signatures to the town government
After repeated discussions with JR Shikoku
the local government decided that it would be difficult to keep the station building
JR Shikoku will bear the cost of dismantling it
and the municipality will construct a new wooden station building of about 45 square meters
the Nishi-Sakawa Station building on the Dosan Line was transferred to the Sakawa town government in Kochi Prefecture from JR Shikoku
The town government spent about ¥16 million to make it earthquake-proof and renovate it
The 100-year-old structure will house a facility to promote the nearby clear Niyodo River basin
The station building was used on a poster promoting the JR Group’s “Seishun 18 Ticket,” a pass that allows unlimited rides on regular trains throughout Japan
“We are glad to keep the station building as a symbol of the community,” a town official said
a professor at the National Institute of Technology
said that the simplification of the station building was unavoidable due to JR Shikoku’s financial situation
if the station building loses its function as a space for people to gather and interact
the area around the station may become desolate
The railroad may fall into a vicious cycle in which people do not use the station any longer.”
Miyazaki is calling on both the municipal government and railway companies to find ways to attract people to the station building
Tokushima — Construction has begun on a cycling road on the 1.6-kilometer-long Onaruto Bridge connecting Shikoku and Awaji Island
The road will offer a panoramic view of the Naruto Strait
and is scheduled to be completed in fiscal 2027
A vacant space had been created on the Onaruto Bridge in anticipation of the development of the Shikoku Shinkansen
which was to connect Honshu and Kyushu with Shikoku
the Shinkansen idea faced profitability issues and never came to fruition
so the idea of putting in a cycling road instead was floated around 2017
Like the Shimanami Kaido cycling road which connects Hiroshima and Ehime prefectures
the road is expected to stimulate regional development through cycle tourism
The new road will have a maximum width of four meters
including both the road itself and a sidewalk
Both sides of the road will be covered with a mesh fence to allow for a better view
The Hyogo Prefectural government will contribute ¥3 billion and the Tokushima Prefectural government ¥2.8 billion to meet construction costs
The groundbreaking ceremony for the cycling road was held in Naruto
attended by the governors of Hyogo and Tokushima prefectures
Although the Shikoku Shinkansen is not currently expected to be built
the Tokushima prefectural government will remove the cycling road if plans change

One in three people in Tokushima prefecture was over 65 years old in 2019, according to Japanese government statistics. This gives the immediate context for the research that Tokushima University scientists are conducting into various aspects of ageing.
Located on Shikoku island in western Japan, Tokushima University is aggressively pursuing innovation. Under the leadership of President Sumihare Noji, the university is implementing organizational reforms to support its researchers. “We’ve been enacting various internal reforms to better position ourselves to realize our mission of helping solve some of the world’s most pressing problems,” Noji says.
The university is actively building on its scientific strengths, particularly those in the fields of photonics and medicine. Tokushima University is the alma mater of Shuji Nakamura, who was jointly awarded the 2014 Nobel prize in physics for inventing the blue light-emitting diode (LED). Advancing this proud tradition, the university’s Institute of Post-LED Photonics is developing new applications of light for communications and medicine.

In addition, researchers at the university’s Institute of Advanced Medical Sciences are developing treatments for intractable diseases and chronic diseases based on their collective expertise in the molecular functions of enzymes and other key proteins. Other outstanding work is being done by researchers at the Bio-Innovation Research Center, who are developing novel biomedical technologies to ensure the sustainable growth of society.
One example of a successful seed is fusion research involving optical engineering and medical science, which has become one of the university’s flagship research projects. By combining advanced optical and diagnostic probe technologies, the team has recently developed a technology that can easily and rapidly detect SARS-CoV-2, the virus that causes COVID-19.
The research cluster system also helps to foster young researchers. As a result, the university was awarded two government-funded projects this year for encouraging doctoral students to attempt ambitious and interdisciplinary projects and to grow as future innovators.
As Japan is ageing faster than any other country, Tokushima University is focusing on ageing research to extend people’s healthy longevity. Three clusters are tackling different aspects of ageing.
Indigo dyeing is a traditional craft in Tokushima that many older people practice. Three groups at Tokushima University are tackling the issue of ageing with a view to extending the healthy longevity of people.
Yoshihiro Uto, a medicinal chemist at the Graduate School of Technology, Industrial and Social Sciences, has developed nanotechnologies that aim to aid the regeneration and activation of ageing skin cells. He is collaborating with venture company Saint Clair, which has its headquarters in Tokyo and is headed by CEO Kaori Kunikata, to research and develop highly functional cosmetics based on scientific evidence.
To meet such growing demands, Tokushima University became Japan’s first national university in 2016 to run a crowdfunding scheme to support both university projects and local and municipal projects that contribute to society. No other university has independently launched similar initiatives.
As of September 2021, the crowdfunding scheme has raised 125 million yen for 93 projects, including 70 million yen for the university’s 39 projects. For example, one project, which received more than 9 million yen, will help disseminate an innovative surgical method to treat scoliosis under local anesthesia by using a very thin, next-generation endoscope.
In 2018, Tokushima University established the Industry–University R&D Startup Leading Institute (INDUSTAL) to swiftly commercialize research outcomes. INDUSTAL provides strong support to researchers so that they can focus on their research. This support includes negotiating with companies wanting to collaborate with them, helping them register their intellectual property, and providing funding to establish startups.
“INDUSTAL has transformed the way the university collaborates with industry,” says Yoshida. “In the past, collaborations used to be one-time, small-scale projects such as joint research between individual researchers and companies, but many projects have now evolved into ongoing inter-organizational collaborations with a view to realizing social implementation.”
INDUSTAL actively promotes entrepreneurship, and students have launched three start-ups. The university has established about 30 start-ups, which include ones that are developing gene-editing technologies, producing edible crickets as a next-generation protein source, and conducting measurement-based research using advanced laser and plasma technologies. In 2020, Tokushima University received 140 million yen (roughly US$1.23 million) in patent revenues – a record for the university.
While much progress has been made, Tokushima University is committed to pursuing further reforms, Noji says. “We will keep striving to foster global leaders through collaborations and researcher exchanges and address key solutions to ensure global sustainable development.”
rural region in Western Tokushima where thatched hamlets and patches of farmland cling to the mountainsides
Where is Iya Valley?Iya Valley is located in western Tokushima in northeast Shikoku
which is the smallest of Japan’s four main islands
hung between the big-hitters of Hiroshima and Kobe
crossing the Seto Inland Sea by suspension bridges
the region remains less visited by international tourists
Iya — which translates to ‘ancestor valley’ — is Shikoku’s dark heart: a tree-mantled
mountainous time capsule carved up by monumental valleys and rushing
It’s roughly divided into two regions: Nishi-Iya
a more accessible region along the great Yoshino River
one of the deepest and most secluded parts of Japan
Iya Valley is a throwback to an old-world Japan
a region which hasn’t quite caught up with the rest of the country
the first roads into Iya only appeared in the early to mid-20th century
self-sufficient populace was left to develop alone
The result is an anomalous culture of hilltop towns
Iya’s impregnable landscape also made it a hideout for political exiles
who built the region’s best-known attraction: its three remaining vine bridges that crisscross above the Iya River
Iya abounds with spectacular scenery of steep
unfathomably blue-green rivers and veils of verdant forest that shift with the seasons
One of its strangest attractions is Nagoro
where one villager has tackled the dwindling population by replacing people with life-size dolls
Iya Valley offers hikes along dramatic cliffside trails
canyoning through glassy pools and some of Japan’s best white-water rapids at Koboke Gorge
despite them being renewed every three years and now secretly bolstered by cables
As relatively few tourists make it to Iya Valley
it’s ideal for off-the-beaten-track travel and those hoping to experience an entirely different side of Japan
plus its rice-free food culture thanks to its inhospitable agriculture
Iya Valley is famed for its unique vine bridges (called kazurabashi) that hang over the Iya River
Each is made from several tons of wisteria vines that are gathered from the surrounding mountains

A horseshoe of emerald water parts the towering
which you can enjoy from a lookout above or on a boat tour below
Iya Valley's rivers also offer incredible class three and four rapids
with stony chutes and roiling waters broken briefly by more serene sections
you’ll find authentic crafts and architecture
you can still see preserved samurai houses and spot the increasingly elaborate udatsu in Wakimachi and Sadamitsu
these roofed walls became a status symbol for Iya Valley’s tobacco and indigo traders
a Buddhist temple complex featuring 1,300-year-old temples
you can see hillside village life and stay in one of the traditional thatched kominka buildings
The unique cuisine of Iya Valley is another highlight
with soba (buckwheat) replacing traditional rice
Tuck into hot stews of soba noodles and soba rice
with each season offering a different aspect and activity
Spring and autumn are the best times to see the changing landscape
cherry trees paint the river valleys pink with sakura
while autumn foliage lights up in scarlet and saffron
Summer brings long days for hiking Oku-Iya’s interior
clear skies for stargazing and the best weather for tackling river rapids
Winter is the hardest season to travel through the valley
making its narrow snaking roads harder to navigate
winter is great for exploring traditional towns like Sadamitsu
cosying up with a hot sake from one of the local breweries
where you can bathe in hot spring waters and watch snow fall across the mountains

Ningyo Joruri, a traditional form of Japanese puppet theater has been around for hundreds of years. Along with kabuki, it was a major form of popular theater entertainment during the Edo Period
and multiple on stage puppeteers for each puppet
Entrance to the Awa Jurobe Yashiki Puppet Theater & Museum
Ningyo means "doll," and joruri is a kind of chanted storytelling accompanied by shamisen. When the two were brought together in early 17th century Osaka
Bunraku grew in popularity largely due to the influence of the famous playwright Chikamatsu Monzaemon
sometimes referred to as the "Shakespeare of Japan."
Known mostly for his kabuki plays, many were actually written for puppets and later adapted for kabuki
Displays in the puppet museum in TokushimaOne of the large puppets on display at Awa Jurobe Yashiki
Bunraku was more popular in Osaka in the west of Japan (Kansai) than in Edo (Tokyo) and the east (Kanto)
which is why the National Bunraku Theater is in Osaka
One of the best places to see puppet theater nowadays is in Tokushima on Shikoku
where the puppet shows were particularly popular in the countryside
The puppets were also bigger here than in other parts of the country
A scene from a performance of Awa Puppet Theater
The Awa Jurobe Yashiki in Tokushima city offers a convenient and inexpensive way of seeing some traditional Japanese puppet theater
The theater is in the grounds of a traditional house and garden that belonged to a rich indigo merchant by the name of Bando Jurobe
Before watching the performance it is worth having a look at the garden
There is also a museum with displays of puppets and related materials especially on the puppet heads which can be remarkably complex
Most of the exhibits have information in English
You can also watch a video about Awa Ningyo Joruri
The performance itself is of several scenes from the tragedy Keisei Awa-no-Naruto
and the main character is Bando Jurobe himself
For performances on weekends and holidays the chanter
who supplies voices for all the characters
and the shamisen player sit in a separate space to the right of the stage
After the performance the puppeteers come down from the stage with the puppets for photo-ops with the audience and chatting
Tokushima 771-0114Tel: 0886 65 2202Open 9.30 am to 5 pm
Closed over the New Year.Entry is 410 yen for adults
300 yen for high school and university students
The theater is 25 minutes from Tokushima Station stand 7
The Tourist Information office near the station has a timetable
or if you want to see more about Awa puppetry
then the Awa Doll Museum in downtown Tokushima is a must see
Not at all well known and not included in most tourist information is this quite large exhibition of puppets and related materials and is completely free to enter
a large culture center and auditorium along the river west of and about 600 meters from Tokushima Station
A small entrance on the main street leads to elevators up to the fifth floor
There are several large galleries with many dolls
Also on display are other materials including a replica of the backstage area of a rural puppet theater filled with costumes and paraphernalia
One room has large photos of puppets photographed in a multitude of surroundings
There is probably as much on display in this museum than at the Awa Jurobe Yashiki
but there is no English information and no staff
Tokushima 770-0835Tel: 0886 22 8121Open 9.30 am to 5 pm
For those with more than a passing interest in Japanese puppetry might want to visit the Tenguhisa Museum
This was the home and studio of one of the artists who made the puppet heads in the early 20th century
Traditionally the puppeteers themselves made the costumes and the main body of the puppet
but making the intricate heads was the job of specialized artisans
This was the work of Tengu Hisashi who was the third generation in his family
You can watch a DVD of a TV program made about him and the volunteer staff can explain more
but it is quite interesting just to see the workshop left as it was when in use
Tokushima-shiTokushima 779-3121Tel: 0886 643 2231Open Thursday to Sunday from 9.30 am to 4 pm
The museum is a short walk from JR Ko Station on the Tokushima Line. Tenguhisa Museum is not far from Kannonji and Idoji, the 16th and 17th temples on the Shikoku Pilgrimage

This article is part of the Research TopicAre Rodent Models Fit for Investigation of Human Obesity and Related Diseases?View all 17 articles
Understanding the neural systems underlying the controls of energy balance has been greatly advanced by identifying the deficits and underlying mechanisms in rodent obesity models
The current review focuses on the Otsuka Long Evans Tokushima Fatty (OLETF) rat obesity model
significant progress has been made in identifying the causes and consequences of obesity in this model
Fundamental is a deficit in the cholecystokinin (CCK)-1 receptor gene resulting in the absence of CCK-1 receptors in both the gastrointestinal track and the brain
OLETF rats have a deficit in their ability to limit the size of meals and in contrast to CCK-1 receptor knockout mice
do not compensate for this increase in the size of their spontaneous meals
Prior to becoming obese and in response to pair feeding
OLETF rats have increased expression of neuropeptide Y (NPY) in the compact region of the dorsomedial hypothalamus (DMH)
and this overexpression contributes to their overall hyperphagia
Study of the OLETF rats has revealed important differences in the organization of the DMH in rats and mice and elucidated previously unappreciated roles for DMH NPY in energy balance and glucose homeostasis
Characterization of overall pancreatic function in OLETF rats demonstrated the absence of a pancreatic amylase response to administration of the brain gut peptide cholecystokinin (CCK) (2). Further studies revealed that OLETF rats had a >6 kbp deletion in the gene for the CCK-1 receptor that spanned the first and second exons and resulted in the absence of expression of a functional CCK-1 receptor (3)
the OLETF rat is a CCK-1 receptor knockout model
There are important species-specific differences in the expression patterns of CCK-1 and CCK-2 receptors
including the expression of CCK-2 and not CCK-1 receptors in human pancreas
the expression of CCK-1 receptors in vagal afferent neurons and in specific brain sites appears to be similar in rat and man (not in the mouse as will be discussed later)
The satiety actions of CCK depend on the interactions with CCK-1 receptors. Sulfated CCK-8 or sulfated longer forms (i.e., CCK-33, CCK-58) inhibit food intake in a dose-related fashion, while unsulfated CCK or shorter CCK fragments do not (4, 19). Furthermore, specific CCK-1 antagonist administration increases food intake while CCK-2 antagonists do not (7)
This pharmacological specificity has been demonstrated across multiple species
Figure 1. Meal patterns in LETO and OLETF rats (20)
The food intake of OLETF rats is also characterized by higher preferences for high fat (23), sucrose and other sweet tastes (24)
This can be demonstrated in both real feeding and sham feeding paradigms
implicating taste mechanisms in the preferences
Pair feeding experiments in which the daily intake of OLETF rats was limited to that of paired LETO control rats revealed that the obesity in the OLETF rats was completely attributable to their hyperphagia. Pair feeding completely normalized their rates of body weight gain (Figure 2) as well as the size of their fat mass and their glucose regulation (20)
the OLETF rat is an obesity model of disordered food intake
Figure 2. Pair feeding normalized body weight in growing OLETF rats (20)
Why does the absence of CCK-1 receptors result in obesity in the OLETF rat
These data have led to the hypothesis that the obesity in the OLETF rats results from a combination of disordered satiety signaling due to the lack of vagal afferent CCK-1 receptors and an upregulation of DMH NPY that prevents complete compensation for the increased meal size
The CCK-1 receptor knockout mouse has similar deficits in the control of meal size
but in the absence of altered DMH signaling
appropriately compensates for chronically consuming larger meals
The age-dependent aspect of the effects of exercise may depend on epigenetic effects in pathways undergoing maturation and thus increasing the possibility of lasting effects when the exposure is at a younger age
The observation of altered DMH NPY signaling in the OLETF rat and how DMH knockdown rescues the obese phenotype has led to extensive studies of the roles of DMH NPY in various aspects of energy balance. As mentioned above, overexpression of DMH NPY leads to increased food intake and body weight, especially when rats are presented with a high-fat diet (30)
providing a potential novel target for obesity treatment
Work with the OLETF rat has not only been focused on identifying the mechanisms underlying its obesity but also served as a vehicle for uncovering multiple novel mechanisms involved in the overall controls of energy balance
Both authors have approved the final version of the manuscript
The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest
