Hokkaido University and Japan's forestry institute modelled all 349 ski areas in the country. At 4°C of warming, only seven stay open 100 days a year on natural snow. At 2°C, 53 do.
Desalination makes about 35 trillion liters of fresh water a year and discards roughly 50 trillion liters of brine. A Tokyo lab drips it onto molten tin and recovers magnesium oxide, 280 times concentrated.
Japan's Environment Ministry will stop subsidising the purchase of conventional solar panels for new projects from fiscal 2027. The stated reason was not carbon but industry: the money was benefiting factories abroad.
A kawakawa hybrid made bluefin tuna sperm at eight months, and rainbow trout now spawn Chinook salmon yearly. Inside Japan's 20-year surrogate broodstock effort and Kindai's 32-year tuna project.
Kobe University isolated seven bacterial strains from PFAS-polluted river sediment in Osaka. Three cut PFOS by up to 17.8%; one removed up to 97% of PFHxS in real landfill leachate. Degradation or adsorption? Unsettled.
Pacific fishing nations agreed on August 18, 2026 to raise the quota for bluefin tuna over 30 kilograms by 25 percent, to 14,836 tons in the western Pacific, and to cut the quota for juveniles by 6 percent.
Japan's 2025 seafood output fell to 3,577,400 tonnes, the lowest since 1956, while FAO puts world production at 235 million tonnes. Comparing quota rules with Norway and the US shows why fewer fishermen isn't the answer.
Researchers at the Institute of Science Tokyo have created a surface electrene: a crystal whose outermost layer is a sheet of loose electrons, with a work function lower than cesium. It survives open air because nitrogen caps it, then leaves as ammonia. Here is what it means for green fertilizer, and how it compares with the electrochemical routes pursued in China, Europe and the US.
NEC and New York University estimate that flood defenses on the Rockaway Peninsula could avoid up to $800 million in losses, pricing everything from transit disruption to residents' mental health in a bid to pull private money into climate adaptation.
Mitsubishi Gas Chemical has signed an MOU with Australia's Gold Hydrogen to study green methanol made from natural hydrogen in South Australia. Here is why a Tokyo chemical maker is going to the wellhead abroad, what the Toyota-ENEOS consortium is really buying, and how the global race for natural hydrogen is splitting along national lines.
Toray's new TSW-K/M/V RO membranes remove over 99.9% of salt and enough boron to run seawater desalination in a single pass, trimming energy, equipment and cost. Here's why it matters worldwide.
Kubota says its existing waste-melting furnaces destroyed three regulated PFAS at over 99.999 percent, with greenhouse-gas markers below detection. We check whether 'destroying forever chemicals' is really the breakthrough it sounds like.
JR East will phase out magnetic short-distance train tickets in spring 2027, replacing them with QR-code paper tickets. We break down the environmental and cost reasons, why almost no one will notice, and the small ritual that is quietly disappearing.
Aquaponics rarely pays as a standalone farm. So how does Aomori's closed-school project plan to make money? By monetizing the cafe, tours, education and welfare work around the tank, backed by public funds.
Yokkaichi City handed its reservoir grass-cutting to nine goats, dropping annual costs from $5,000 to $3,100. Meet the hungriest grounds crew in Japan and the comeback of goat grazing.
In 2002, Japan's Kindai University pulled off the world's first full-cycle bluefin tuna farming. Two decades on, the major seafood companies are walking away and commercial output is fading. The irony: the headwind is the recovery of wild tuna stocks. A look at the gap between sustainable and profitable.
A Japanese radiative cooling film that stays below air temperature in direct sun, with zero electricity. How SPACECOOL dumps heat into space, its 29% energy cut in Saudi trials, and why passive cooling matters as the planet warms.
Japan discards 650,000 tons of small electronics a year, yet recovers only a little over a tenth of it. The rest mostly leaks abroad through an untracked invisible flow. On June 5, 2026, the Environment Ministry picked six pilots enlisting movers and couriers to keep the metals home.
With water that is neither sea nor fresh, Okayama University of Science is trying to farm salmon through its entire life cycle on land. If it works, the university calls it a world first. We unpack the technology behind it, why salmon is the hardest fish to farm this way, a 250-year-old salmon town's role, and the global scramble for farmed salmon.
Researchers at Yokohama National University built a photocurable resin that hardens with light and melts back to liquid with heat. Using anthracene photodimerization, it recycles 10-plus times with no initiators or additives.
