Ainoshima, a tiny island off Fukuoka, is home to roughly 200 cats that outnumber its 270 human residents. Named one of CNN's top 6 cat spots worldwide, this heart-shaped island is going viral again on TikTok and Instagram in spring 2026. Discover the fishing village coexistence, TNR efforts, and how to visit.
Osaka Metropolitan University researchers discovered that butterflies raised on invasive plants develop altered wing coloration, making them less attractive to potential mates. The study reveals how changes in larval diet affect UV reflection patterns and reproductive success.
WWF Japan reveals shocking data on pet-origin invasive species, while Amami Oshima achieves the world's largest mongoose eradication. A deep dive into 20 years of Japan's invasive species law.
After record-breaking 238 bear attack victims and 13 deaths in FY2025, Japan's Ministry of Environment unveils revised guidelines introducing expanded exclusion zones and a new 'enhanced management area' to separate humans and bears.
Brainless jellyfish and sea anemones sleep about 8 hours a day and even take naps, new research reveals. Sleep's true purpose isn't brain rest; it's repairing DNA damage in neurons. Discover how this 500-million-year-old function connects jellyfish to human sleep health.
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.
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.
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.
