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.
The University of Tokyo's Kono Lab, with Aisin and ARM Technologies, ran the world's first end-to-end demo storing green hydrogen in a room-temperature, non-flammable liquid, moving it between cities in a simple container, and generating power directly. We unpack the efficiency claims against ammonia and MCH, and how it diverges from US, European and Chinese hydrogen-carrier strategy.
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.
A single fusion reactor needs about 10,000 km of high-temperature superconductor tape, and five years ago almost no one could make that much. Now four Italian physicists at startup Suprema are building Europe's largest tape plant to break in. But the companies that already dominate this wire are mostly Japanese: two of the four global fusion-grade producers are based in Japan. Inside the race over the thin ribbon fusion runs on.
Kagawa, Japan's self-styled udon prefecture, throws away thousands of tons of noodles a year. Two teams found wildly different uses for the waste: a small factory that turns it into electricity, and a professor who turns it into surprisingly tough paper grown by microbes, now made at a welfare facility for Marugame's traditional fans.
Waseda University and Fujitsu used quantum circuit learning (QCL) to predict the hardness of high-entropy alloys from only about 100 data points. We explain how a quantum approach tackles the small-data extrapolation problem that defeats conventional machine learning, where it sits against IBM and Google quantum efforts, and what it could mean for industrial materials discovery.
Hoku Energy K.K., the Japanese subsidiary of UK-based Hoku Infrastructure, will build Japan's first new-build 100% hydrogen mono-firing thermal power plant in Aomori Prefecture. The 106.6MW Daiichi Plant, awarded under Japan's 3rd Long-Term Decarbonized Power Source Auction, is scheduled to start operations in the early-to-mid 2030s. We compare it with hydrogen power efforts by Plug Power, MHI in Utah, Linde, Air Liquide, and South Korea's Doosan, and explain what it means for Japan's GX strategy.
Kawasaki Heavy Industries has begun pitching a technology that produces naphtha, the building block of plastics, from hydrogen instead of crude oil. Built on its commercial gas-to-gasoline plant in Turkmenistan, the proposal lands in the middle of a Japanese petrochemical crisis triggered by the Strait of Hormuz disruption.
In spring 2026, Honda wrote off roughly $10 billion in EV development. That same season, US ITER closed out the supply of ITER's 1,000-tonne central solenoid, the UK's Pulsar Fusion ignited the first plasma inside a fusion rocket engine, and Kyoto Fusioneering pushed on with its integrated fusion fuel cycle test facility in Canada. Stack the candidates in watt-hours per kilo and the picture is brutal: nothing beats gasoline in a form you can put in a car, except one category up, where fusion sits at 7.8 million times the density. Win the bet and you unlock effectively free electricity, working climate reversal, Mars in two months, lunar helium-3, and the solar system as a shipping route. Honda's mistake alone covers nearly 40 percent of ITER's budget. Maybe it's time to stop arguing about EVs and just go build the sun.
Between March and May 2026, Japan launched a wave of perovskite solar cell demonstrations across the country—world efficiency records, rice paddies, mountain tea fields, skyscraper windows, highway parking areas, and Toyota's Woven City. We unpack for international readers why everything is happening at once.
In 2012, the Sankei Shimbun reported a biofuel revolution centered on Enomoto algae, a hyper-growth Botryococcus bred by Kobe University spin-off G> under Professor Taira Enomoto. Heavy-industry giant IHI joined biotech venture Neo-Morgan Laboratory to commercialize it, with then-CEO Tomohiro Fujita declaring he wanted to cut the price to one-tenth within ten years. Fourteen years later, the joint venture has dissolved, but the algae fueled the world's first flight on SAF meeting ASTM D7566 Annex 7, and a Japanese-led 5-hectare facility in Malaysia is now the largest of its kind on Earth. Did the promise come true, or is the dream over?
