Japan Backs Rapidus Chip Push
Japan approved roughly ¥631.5 billion in subsidies to help Rapidus enter AI chipmaking, marking another national push to onshore advanced semiconductor capacity. (x.com) The funding is part of a broader strategic effort to reduce dependence on foreign fabs as AI demand makes chip sovereignty a policy priority. (x.com)
Japan just put another ¥631.5 billion, about $4 billion, behind Rapidus, a chip company that did not exist before August 2022 and now has a state-backed deadline to mass-produce 2-nanometer semiconductors in fiscal 2027. (reuters.com) That new approval lifts Rapidus’s research and development support from the Japanese government to about ¥2.354 trillion, which is roughly the size of a national industrial rescue plan, not a normal startup funding round. (reuters.com) Rapidus is trying to make logic chips, which are the “brains” chips that run data centers, smartphones, and artificial intelligence systems, not the older “memory” chips Japan once dominated. (rapidus.inc) The company’s target is 2 nanometers, a label used for the most advanced generation of chipmaking, where tiny gains in size and wiring can decide who gets the fastest artificial intelligence servers and the lowest electricity bills. (ibm.com) Japan is not starting from zero, but most of its recent semiconductor comeback has been about mature chips in Kumamoto through Taiwan Semiconductor Manufacturing Company’s Japan Advanced Semiconductor Manufacturing plants, not the absolute cutting edge. (tsmc.com 1) (tsmc.com 2) Rapidus is the part of the plan aimed at the top of the market, and it is building that bet in Chitose, on Japan’s northern island of Hokkaido, at a site called Innovative Integration for Manufacturing-1. (rapidus.inc) The factory moved into pilot-line operation in April 2025, which means it started running the first version of the production process before full commercial output, the same way a carmaker tests a line before selling thousands of cars. (rapidus.inc) Rapidus is not doing this alone. It has a 2-nanometer technology partnership with International Business Machines, and in June 2024 the two companies expanded that relationship to chiplet packaging, which is the method of snapping smaller chip blocks together like Lego pieces inside one package. (ibm.com) In July 2025, Rapidus said it had successfully operated gate-all-around transistors for 2-nanometer chips, a transistor design that wraps the switch more tightly so current leaks less and performance improves. (rapidus.inc) The April 11 package also reaches beyond one factory. Japan’s New Energy and Industrial Technology Development Organization said it will support semiconductor design-related projects by Fujitsu and IBM Japan, which means Tokyo is trying to line up future customers and designers before Rapidus reaches volume production. (reuters.com) Rapidus also raised ¥267.6 billion on February 27, 2026 from the government and private-sector companies, with the company saying that money would help carry it from research into mass production by 2027. (rapidus.inc) The gamble is simple: if Rapidus works, Japan gets a domestic source of frontier chips just as artificial intelligence demand turns semiconductors into national infrastructure; if it misses on yield, cost, or schedule, Tokyo will have spent trillions of yen chasing a market now ruled by a handful of giants.
