In 2012, the Sankei Shimbun reported a biofuel revolution centered on Enomoto algae, a hyper-growth Botryococcus bred by Kobe University spin-off G&GT 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?

Japan's Resonac (formerly Showa Denko) will switch its Kawasaki ammonia plant to 100% waste-plastic-derived hydrogen by April 2030, ending its reliance on natural gas reforming. The world's only long-running commercial gasification chemical recycling plant processes 70,000 tons of plastic waste annually to produce 120,000 tons of ammonia, with 80%+ CO2 reduction. Now backed by Japan's first CCfD-style price-gap subsidy. A circular alternative to urban mining.

By fiscal 2034, new data centers and semiconductor fabs will add peak electricity demand equal to seven nuclear reactors in Japan, with roughly 60 percent of capacity clustered around Tokyo and the connection queue backed up. The government's answer is Watt-Bit Integration. Set against Virginia's pricing fix, Ireland's renewables mandate, and Singapore's hard area cap, Japan's regional-distribution-plus-decarbonization bet comes into focus.

An in-depth look at Japan's Hydrogen Arterial Plan (Suiso Daidomyaku Koso), unveiled by METI in April 2026. Six priority regions connected by arterial highways will receive concentrated investment of 15 trillion yen by 2040, with Toyota and Chiyoda starting mass production of electrolyzers in 2029. How Japan's strategy compares with the US IRA and the EU Hydrogen Bank.

Susumu Kitagawa of Kyoto University, joint winner of the 2025 Nobel Prize in Chemistry, has long advocated turning air itself into a resource through metal-organic frameworks (MOFs). His porous crystals can sort and capture CO2, water vapor and other molecules, putting Japan in direct conversation with players like Switzerland's Climeworks in the rapidly evolving direct-air-capture industry. Here is how a basic-science breakthrough from Kyoto could rewrite the economics of decarbonization.

On March 25, 2026, five partners, NYK Line, NTT Facilities, Eurus Energy, MUFG Bank, and the City of Yokohama, launched a world-first floating data center powered entirely by solar panels and batteries at Yokohama Port. How does this off-grid demonstration differ from the MOL-Hitachi used-ship concept, and what does it say about Japan's answer to the AI power crisis?

Japan's QST and NTT achieved a world-first: real-time communication under 100 microseconds for fusion plasma control. Learn how this JT-60SA breakthrough connects to IOWN and ITER.

DENSO and the University of Tokyo signed a 10-year partnership starting April 2026 centered on Dynamic Wireless Power Transfer (DWPT). Learn how charging EVs while driving could shrink batteries, cut costs, and reshape energy infrastructure — plus how Japan's approach compares to Sweden, Israel, and the US.

Sekisui Chemical has officially launched SOLAFIL, Japan's first commercially produced film-type perovskite solar cell. Lightweight and flexible enough for walls and curved surfaces, this next-gen technology positions Japan at the forefront of the global perovskite race against Chinese and European rivals.
