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.
Terahertz promises jaw-dropping 6G speeds, yet a passing body can kill the link. NICT just demonstrated the world's first system that auto-switches between millimeter and terahertz waves. The real breakthrough isn't a speed record but knowing when to give up on speed.
A University of Tokyo and RIKEN team has switched a magnet in just 40 picoseconds with almost no heat, using the antiferromagnet Mn3Sn. Published in Science, the result shatters the nanosecond speed limit that has held back chips for years. Here is why the wall stood, and how it fell.
Light travels faster through air than glass. By hollowing out the core, OKI, Lightera and Keio University demonstrated a world-first wideband single-fiber bidirectional link. Commercialized, it could cut network power by up to 90 percent. We unpack the race, where Microsoft is already in via its Lumenisity buy, as AI devours electricity.
Free-space optics sends data on beams of light without cable. The idea dates back to Bell's 1880 photophone. Here is why a 140-year niche technology is now moving toward disaster recovery and remote connectivity, from Taara to Japan's NEC and NICT.
Asahi Kasei has developed a photosensitive polyimide film for advanced semiconductor packaging, turning a liquid material into a laminated film, the same playbook behind ABF. We explain what it means for AI chiplet packaging, how it stacks up against US and Korean rivals, and why Japan keeps winning the materials game.
OpenAI is moving to offer its newest cyber-focused AI model, GPT-5.5 Cyber, to the Japanese government and industry. Former NSA Director Paul Nakasone, now an OpenAI board member, flew to Tokyo to pitch critical-infrastructure cooperation. We unpack the contrast with Anthropic's tightly controlled Claude Mythos, the China-threat framing, and what it means that OpenAI wants Japan as its first international partner.
Yokohama National University spinoff LQUOM has closed a 1.23 billion yen ($7.7M) Series B to build quantum repeaters, the missing piece of the quantum internet. Here is what that means, and how it stacks up against Aliro in the US, USTC in China, and Japan's planned Tokyo-Osaka quantum backbone.
Why a Nissan deep in restructuring picked Red Hat for its next-generation in-vehicle OS. We unpack the trap of in-house software development that cost Volkswagen's CARIAD 14 billion euros, and the path Nissan chose to avoid it.
Anthropic's Head of Global Affairs Michael Sellitto arrived in Tokyo May 15 and confirmed the company is weighing participation in the cyber defense corporate alliance proposed by Japan's ruling LDP. Modeled on US Project Glasswing, the framework will test Japan's distinctive 'middle path': an AI Promotion Law with no penalties, sitting between the EU AI Act's hard regulation and the deregulatory turn under the Trump administration.
Japan's next-gen supercomputer Fugaku NEXT bets against the cooling consensus: warming water above 30°C to cool AI servers and cutting cooling power by 20%. It may also adopt 'ZAM,' a new memory developed by SoftBank and Intel that stands DRAM chips on edge with magnetic-field coupling. Why Japan is choosing efficiency over the gigawatt-scale arms race that defines US Frontier and El Capitan.
