JR Kyushu's new RK System will control trains over public cellular networks starting 2028—a Japan-first approach. How it compares to Europe's ERTMS and America's PTC, and what it means for aging societies everywhere.
Alpaca, founded by two Japanese entrepreneurs in Silicon Valley, hit a $1.15 billion valuation in its Series D round, becoming the first Japanese-founded US unicorn. Serving SBI Securities, Kraken, and 300+ institutions across 40 countries, it aims to be the 'AWS of finance', alongside Plaid and Stripe. Why did they build this in America, not Japan?
Tokyo-based Orbray has produced the world's largest 30mm square (111) freestanding diamond single-crystal substrate, leaping from the previous few-millimeter limit. The twin-suppression breakthrough, published in Applied Physics Express, unlocks NV-center quantum sensors and next-generation power semiconductors.
NTT and JAXA have completed the world's first orbital demonstration of satellite MIMO communication and IoT sensing technology aboard a low-Earth orbit satellite. By applying MIMO, the same technology that speeds up your smartphone, to space, they aim to double satellite data transmission capacity. The breakthrough could bring IoT connectivity to mountains, oceans, and remote islands where no cell towers exist.
Kyoto University's AI-powered robot monk Buddharoid now offers spiritual guidance at a Kyoto temple, trained on ancient Buddhist scriptures. With 30% of Japan's 77,000 temples projected to vanish by 2040, can artificial intelligence save Buddhism? From the $1M Mindar android to BuddhaBot chatbots reaching Bhutan, we explore where faith meets technology.
Japanese lunar startup ispace has unveiled 'Lunar Connect,' a communication and positioning service using lunar orbiting satellites. Partnering with KDDI for ground stations and planning 5 satellites by 2030, ispace is pivoting from a transport company to a space infrastructure provider. The new unified ULTRA lander marks another strategic shift.
Tokyo deep-tech startup H.I.Council has performed the world's first 108-qubit FeMoCo calculation on IBM's Heron r2 processor. While achieving chemical accuracy via classical methods, the team discovered a quantitative hardware limit they call the 'coherence wall' — a constructive finding for quantum hardware development.
Researchers at Utsunomiya University have provided the world's first direct proof that ceramide deficiency in the skin causes atopic dermatitis. Using transgenic mice, they demonstrated the full disease cascade from barrier breakdown to allergic inflammation — opening doors for ceramide-based therapies and enzyme-targeting treatments for the 200+ million people affected worldwide.
RIKEN and Osaka University have launched cloud access to Ei-II, a domestically developed 144-qubit superconducting quantum computer. Doubling the previous 64-qubit Ei, the 28x28mm chip enables quantum calculations beyond classical simulation. We compare it with IBM and Google systems and examine Japan's quantum roadmap.
TOPPAN Holdings, Japan's NICT, and Canada's ISARA have demonstrated a seamless migration path from current cryptography to post-quantum cryptography in certificate authority systems, without service disruption. The breakthrough addresses the looming quantum computing threat to existing encryption, targeting real-world deployment in healthcare, finance, and government by 2030.
Japanese researchers cloned mice from a single donor for 20 years, producing over 1,200 animals across 58 generations. After the 27th generation, lethal mutations accumulated until all 58th-generation clones died within days of birth — the first proof that mammal cloning has a hard biological limit.
