METI has unveiled Japan's first post-Fukushima numeric target for replacing nuclear reactors: up to 5 by the 2040s, 14 by the 2050s. Behind the decarbonization, energy-security and AI-demand drivers lies a harder question: regulatory capture, the Nuclear Village, and whether the regulator can be trusted.
Why did Yamasa, a soy sauce maker founded in 1645, end up in pharmaceuticals? The story of how umami research led to nucleotides, and to pseudouridine, a key ingredient in mRNA vaccines.
ROHM and Quanmatic put quantum annealing to work on a chip fab's front-end process, lifting output about 3%. Here's why a number that sounds small is actually a big deal on a factory floor.
SBI is rolling Claude out across its entire financial group and bolting it onto the on-chain finance rails it has spent years building. Unlike NEC or Fujitsu, this is a user, not a vendor. We compare how Japan, the US and the EU are wiring AI into finance, regulation included.
Japan's government and three megabanks gained access to a frontier AI model for cyber defense, with the digital minister calling to expand it to critical infrastructure. Set against the new US executive order and the EU AI Act, here is how Tokyo's approach differs.
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.
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.
On June 2, JR East expanded its UK vending business from stations to airports, acquiring around 800 airport machines for a fleet of 1,800. Here's why its touch-screen vending stalled in Japan—and why Britain may be the better bet.
The world's first factory built to mass-produce diamond semiconductors has opened in Okuma, the Fukushima town that hosts the wrecked Daiichi nuclear plant. How a material researchers chased for 40 years found its purpose in the place that needed it most.
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.
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.
