Two wooden walls are bolted down and pulled against each other until one breaks. That is the Kabe-1 Grand Prix, where universities, construction giants and home builders compete for the title of Japan's strongest shear wall. Born after the 1995 Kobe earthquake, it doubles as a public destructive test. Here is how it works and how the 2025 tournament went.
Kyoto Institute of Technology and Chuo University have developed a cooling-free infrared sensor using semiconductor carbon nanotubes (CNTs) with 11x greater sensitivity than conventional materials. Building on Japan's legacy in CNT research since their 1991 discovery at NEC, this breakthrough could transform autonomous driving, security screening, and medical imaging. Here's what it means and how Japan is reacting.
As AI growth makes chip power consumption a critical global issue, Japan's next-generation chip technologies are drawing attention. Tohoku University's MRAM cuts power consumption to a hundredth of conventional chips, while the diamond semiconductors led by Saga University have hit 120 GHz operation and are heading toward space and 6G applications. A report on Japan's technological edge and the competition with the US and China.
No batteries. Just 280 grams of rubber. A Japanese bone-setter turned entrepreneur created "futto," a walking support device using rubber tubes as artificial muscles. Built with hardware store materials by a three-person family company, it now has peer-reviewed backing, a distribution deal with France Bed, and sales abroad. Here's how this $220 device answers a problem every aging society shares.
Beef tendon, a common Japanese hot pot ingredient, is being transformed into knee ligament implant material.
