Chiba Prefecture sits atop an estimated 500-year supply of iodine, the key material in Japan-invented perovskite solar cells. If combined, they could form a fully domestic energy cycle. We break down the potential and the hurdles standing in the way.
An upside-down jellyfish and a starlet sea anemone, neither with a brain, each sleep about eight hours a day and nap. A January 2026 Nature Communications paper argues that what sleep is doing there is not resting a brain but repairing DNA damage in neurons.
A Nagasaki University study reveals nanoplastics transferred through the food chain drastically reduce red sea bream larvae survival rates. With microplastic concentrations 27 times the global average, Japan's coastal waters face an invisible pollution crisis threatening fisheries and marine ecosystems.
Japan's abandoned bamboo forests have expanded to roughly 400,000 acres, causing landslides and destroying ecosystems. Taguchi Industrial from Okayama has answered with the "TakeKaruGon" - a domestically-made mulcher attachment for hydraulic excavators that shreds bamboo, large trees, and stumps in one machine. Discover how this innovation tackles one of Japan's most overlooked environmental crises.
The sweet potato weevil, first eradicated from Japan's Kume Island in 2012 using the world's first successful sterile insect technique on beetles, reinvaded in 2021. A Gifu University-led team verified that rapid response with 3 million sterile insects achieved re-eradication in record time, proving the power of Early Detection and Rapid Response (EDRR) for global pest management.
After removing approximately 20,000 invasive American crayfish over one year, a Japanese pond saw a dramatic ecological comeback—with clear water, thriving aquatic plants, and the return of endangered species. A look at Japan's frontline battle against invasive species and the resilience of native ecosystems.
Japan achieved a world-first by extracting rare earth mud from 6,000m deep near Minamitorishima in January 2026. Explore the latest on Japan's seabed mineral resource development, commercialization roadmap, environmental challenges, and what it means for global critical mineral supply chains.
Over 5,200 protected hermit crabs were illegally poached from Japan's UNESCO World Heritage island of Amami Oshima. Explore the growing crisis of wildlife trafficking driven by overseas pet markets, the limits of current law enforcement, and community-led conservation efforts to protect endemic species.
Japan's latest marine science is overturning long-held beliefs about fish. DNA analysis has dismantled the massive order Perciformes, nanoplastics are dramatically reducing fish larval survival rates, and a world-first observation reveals shortfin mako sharks "warming up" before deep dives. From environmental DNA survey revolutions to new species discoveries, explore cutting-edge fish ecology research from one of the world's most biodiverse marine regions.
A record-breaking 3,000 Steller sea lions have gathered on Benten Island off Hokkaido, Japan. Known as "sea gangsters," they cause roughly ¥1 billion (about $7 million) in annual fishery damage. While internationally protected as endangered, local fishermen face devastating economic losses. Explore this complex conflict between wildlife conservation and human livelihoods.
While Japan faces record bear attacks in 2025 with over 200 casualties nationwide, the resort town of Karuizawa has maintained zero human injuries for 15 consecutive years. Learn how NPO Picchio's innovative approach—using bear dogs, radio tracking, and community cooperation—created a successful model for human-wildlife coexistence that protects both residents and bears.
