The city of Itoigawa, Niigata Prefecture, has been known for its high-quality jade for centuries. In fact, it's considered one of the oldest jade-producing areas and its jade has been used since the prehistoric Jōmon period, long before the Olmec and Maya cultures. Even today, it remains the most notable location in Japan where jade can be found.
This is believed to be due to the city's geological position, where the Fossa Magna and the Itoigawa-Shizuoka Tectonic Line meet. A plethora of minerals formed 20 to 500 million years ago were brought from the mountain ranges in the east, carried by such rivers as the Himekawa. As a result, many of these stones ended up on the coast of Itoigawa, often smoothed over by the current.
In 1994, the Fossa Magna Museum opened not very far from one of the beaches. Many specimens from Itoigawa are exhibited here, including many pieces of raw jadeite from the Jade Coast. The Museum also offers a free service of identification and authentication of minerals found on the Jade Coast, so be sure to check it out if you wish to find out whether your jade is jadeite or nephrite.
The Jade Coast proper is split into three beaches. While the most notable of these is the Itoigawa Beach (also known as the Jade Coast), which is 25 minutes by walk from Itoigawa Station, you can also find jade on the Oyashirazu and Ichiburi Beaches.
There is a 10-minute bus ride from Itoigawa Station to the Fossa Magna Museum. At the museum visitors can also experience a fossil excavation for 300 yen.

Mr Masao Nagasaki has fished the waters off Itoigawa City
Setting out from Tsutsuishi fishing village
the 77-year-old recalls a time when his nets brimmed with fish and shellfish
'Our waters were once teeming with life,' he said through an interpreter
and human activities have drastically altered marine biodiversity
Even as Japan’s first UNESCO Global Geopark
Itoigawa is not immune to the twin threats of climate change and oceanic plastic waste
the local community is responding—transforming their Geopark into a hub for sustainability
By taking an active role in the Geopark’s conservation
people in the community feel more connected to their heritage
Conservation fosters 'pride and love for the land where they live
which becomes the driving force for further activities.'
It is this whole-of-society approach that made Itoigawa City a key destination for a study visit in November 2024 organized by UNESCO under the Sustaining Our Oceans project, funded by Fast Retailing Co., Ltd
The visit brought together educators and conservation officials from three South-East Asian countries to learn from Japan’s marine conservation education programmes and community-driven sustainability practices
Their efforts are now inspiring educators and conservation leaders from Indonesia
and Viet Nam to implement similar strategies in their own UNESCO designated Biosphere Reserves: Wakatobi Biosphere Reserve in Indonesia
and Can Gio Mangrove Biosphere Reserve and Cu Lao Cham – Hoi An Biosphere Reserve in Viet Nam.
'By engaging directly with the Itoigawa community
educators saw firsthand how conservation is woven into daily life—from sustainable fishing practices to youth-led environmental initiatives,' says UNESCO Sustaining Our Oceans project lead Rika Yorozu
'These insights will help shape localized ocean education activities that reflect the realities and challenges of their own UNESCO designated sites.'

A striking example comes from students at Niigata Prefectural Kaiyo High School
who developed Saigo-no-Itteki ('The Last Drop')
Launched in 2013 after three years of research
the project embodies sustainable aquaculture by utilizing every part of the locally farmed salmon.
'I want to keep working in a sustainable way
connecting natural resources to industry without waste,' said Mr Masamune Koyanagi
one of the students presenting the project to the participants.
The Sustaining Our Oceans project follows a similar philosophy
equipping young people across South-East Asia with practical conservation knowledge and skills
Through immersive activities in biosphere reserves
students gain firsthand experience in marine biodiversity
and sustainable practices that link conservation to local economies
By fostering a deeper understanding of ocean stewardship
the initiative aims to prepare communities to protect their marine environments for future generations.

Itoigawa’s community is also addressing marine plastic pollution
Plastic waste does not biodegrade but instead breaks down into microplastics
Chiba Institute of Science Associate Professor Satoko Tezuka
who led the study trip’s participants on a beach cleanup activity
shared her research survey and analysis findings on microplastics around Choshi Geopark on the Pacific coast
'Even the smallest human activities contribute to this crisis
which is why ocean education is crucial,' she said.
The head of the Secretariat at Viet Nam’s Cu Lao Cham – Hoi An Biosphere Reserve
said that the process of extracting microplastics from sand had given him a keener understanding of how microplastics impact local ecosystems.

which in 2024 completed an analysis of Ranong Biosphere Reserve’s learning materials on ocean education and identified educational needs
is already developing an innovative virtual reality game that immerses players in the reserve’s ecosystem
the visit to Itoigawa also reinforced the importance of hands-on learning.
'Seeing how conservation is integrated into daily life at Itoigawa Geopark gave me new ideas for interactive learning at Ranong
We want students to not just study the ecosystem but experience it firsthand—through field activities
and engaging with local communities,' said Ms Poonsri Wanthongchai
Director of Thailand’s Mangrove Research and Development Institute.
the trip was an opportunity to reflect on how similar education models could be applied closer to home
'The visit to Itoigawa showed me how conservation efforts can involve everyone
we plan to integrate these approaches by sharing good practices related to the impact of plastic waste with fellow teachers at my school and teacher community in Wakatobi district to improve waste management at our schools.'
To amplify the impact of Sustaining Our Oceans
the education packages developed for each Biosphere Reserve will be promoted through UNESCO Associated Schools
aligning with global sustainability goals.
By 2050, oceans could contain more plastic than fish
a stark warning that underscores the urgency of conservation efforts
the livelihoods of fishers like Mr Nagasaki—who once set out from Tsutsuishi to nets full of fish—may become a distant memory
But through education and community-driven action
a different future is possible: one where young people across South-East Asia and beyond have the tools to protect the marine ecosystems that sustain the future for all.
The study visit to Japan was made possible with support from Fast Retailing Co.
the Asia-Pacific Cultural Centre for UNESCO
and Associate Professor Tezuka of Chiba Institute of Science.

Dr. Yoshinori Takano and Dr. Atsushi Urai, Biogeochemistry Research Center of the Research Institute for Marine Resources Utilization of JAMSTEC(President: Hiroyuki Yamato), identified the molecular species of the main component of the gas (video) that is actively seeping from Lake Suwa
in collaboration with Shinshu University and the Atmosphere and Ocean Research Institute of the University Tokyo
Lake Suwa is a fault lake located on the Itoigawa-Shizuoka Tectonic Line(ISTL), which itself is located on the boundary between the North American and Eurasian Plates (Fig. 1), with active seeping gas being confirmed at multiple locations in the lake. This “geological hotspot” forms big holes in the midwinter season (Fig. 2)
which then influence the lake ice heterogeneity
the overall understanding of the biogeochemical cycle
including the main components and origins of these gases and their dynamics after being released into the surface hydrosphere
In the present study, the researchers focused on the molecular species present in the gas and conducted a precise molecular-specific stable carbon isotope ratio/radiocarbon isotope ratio (*1) analysis
These results showed that the main component of seep gas was methane
These results also involved a quantitative evaluation of the previously-unknown contribution of deep seeping gas and the surface hydrosphere to the carbon cycle; in the future
these are expected to enable the elucidation of the carbon cycle in fault lakes and the food chain in aquatic ecosystems
This research represents joint research between JAMSTEC and Shinshu University
The results will be published in the specialized academic journal ACS Earth and Space Chemistry
which is published by the American Chemical Society

The national government put the lighthouse on a list of candidates to be decommissioned
but passionate calls for keeping the facility in service within the local communities prompted the municipal government to buy it three years ago to continue its operation
the lighthouse was built by the government of the former Nou town for local fishermen
We negotiated with the Japan Coast Guard (which operated the facility) with the determination to preserve it at any cost,” says Koichi Isogai

Lighthouses used to be vital facilities to guide seafarers safely near the coast
even small ships can navigate safely through dangerous areas without relying on lighthouses thanks to GPS
fishermen say lighthouses are something special for them
“When we spot the light of the familiar lighthouse while sailing toward the port
we feel relieved that we have returned safe and sound to our port,” Isogai explains
“Lighthouses offer emotional crutches for seafarers.”
There are currently more than 3,000 lighthouses in service across the nation
A total of 129 have been retired in the past 10 years
A small number of lighthouses designated to be decommissioned have survived as tourist attractions in Kochi and Ishikawa prefectures

Global warming has increased the frequency of extreme snowfall events in the Hokuriku region by five times
while decreasing overall snowfalls in Japan
“People will need to be more vigilant for avalanches and traffic disruptions in mountainous areas with higher risk of heavy snow,” said Hiroaki Kawase
a senior researcher at the Meteorological Research Institute
a division of the Japan Meteorological Agency
Heavy snowfalls of 52.1 millimeters or more per day occurred more frequently in Hokkaido and mountainous areas in eastern Japan between November 2021 and March 2022
according to the institute’s report released on Oct
Meteorologists used to call snowfalls of such intensity a “once-in-a-decade” event
warmer temperatures have caused more seawater to evaporate
adding moisture to the atmosphere and allowing more snow clouds to form
While these clouds will bring rain in warmer coastal areas
they can cause extreme snowfall events in inland mountainous areas with colder temperatures
The JMA forecasts warmer temperatures and fewer snowfalls this winter
it also warns of heavy snowfall events caused by occasional cold snaps and snow clouds
