Japan backs Rapidus chip push

Japan just put another ¥631.5 billion into a chip startup that did not exist four years ago, taking a much bigger gamble than most governments make on a single factory project. The company is Rapidus, and Tokyo approved the money on April 11 to speed up its research and development work on advanced semiconductors inside Japan. (reuters.com) Rapidus is trying to make the tiny logic chips that run artificial intelligence servers, smartphones, and data centers, not the older commodity chips used in simpler electronics. Its target is two-nanometer production in 2027, which puts it in the same race as Taiwan Semiconductor Manufacturing Company, Samsung Electronics, and Intel. (rapidus.inc) A nanometer in chip marketing is basically a label for how advanced a manufacturing generation is, like saying one car engine is a newer class than another. The smaller-number generations usually pack in more computing power and use less electricity, which is why artificial intelligence companies chase them so hard. (ibm.com) Japan used to dominate semiconductors in the 1980s, when its companies held about half the global market, but it lost ground for decades as Taiwan, South Korea, and the United States pulled ahead in leading-edge logic chips. Rapidus is Tokyo’s attempt to get back into the hardest part of the business instead of staying mostly in materials, tools, and mature components. (wikipedia.org) The company itself was set up in August 2022 with backing from eight Japanese firms: Denso, Kioxia, Mitsubishi UFJ Bank, NEC, Nippon Telegraph and Telephone, SoftBank, Sony, and Toyota. That shareholder list tells you what Japan is building: not just a chip company, but a national supply project tied to cars, telecom networks, consumer electronics, and finance. (rapidus.inc) Rapidus is not building from scratch in the scientific sense, because it licensed and learned from International Business Machines technology for two-nanometer chips. More than 150 Rapidus engineers were sent to Albany, New York, in 2023 and 2024 to train on next-generation manufacturing processes. (rapidus.inc) The factory at the center of this plan is in Chitose on Japan’s northern island of Hokkaido, where Rapidus says it started its pilot line in April 2025. A pilot line is a practice factory: you run test wafers through the machines first, fix defects, and only then try to reach full commercial output. (rapidus.inc) That is why the new subsidy is going to research and development rather than simply paying for more concrete and steel. At this stage, the hard part is getting exotic tools, chemicals, software, and manufacturing steps to work together reliably enough that customers trust you with expensive chip designs. (reuters.com) The scale of the state support is now enormous. Bloomberg reported that the latest decision lifts Japan’s total backing for Rapidus to about ¥2.6 trillion, or roughly $16 billion, which makes this one of the biggest industrial bets in the country’s recent technology policy. (bloomberg.com) Tokyo is not funding only one company. Reuters reported that the same announcement included support for work by Fujitsu and IBM Japan on advanced chips for artificial intelligence, part of a wider plan to invest more than ¥10 trillion in semiconductors and artificial intelligence by fiscal 2030. (reuters.com) The risk is simple: leading-edge chip manufacturing is one of the most expensive and failure-prone businesses on earth, and even established giants struggle to hit deadlines and yields. Japan is betting that supply security, industrial know-how, and a domestic customer base are worth paying for even if Rapidus arrives late and the odds stay long. (bloomberg.com)
