Japan backs Rapidus with $4B

Japan just added 631.5 billion yen, about $4.0 billion, to a chip startup that did not exist before August 2022 and now sits at the center of Tokyo’s industrial policy. The company is Rapidus, and the money was approved on April 11 for fiscal 2026 research and development work. (reuters.com) This is not a rescue of an old factory. Rapidus was created by eight Japanese companies — including Toyota, Sony, Nippon Telegraph and Telephone, SoftBank, Denso, NEC, Kioxia, and MUFG Bank — to rebuild a domestic business Japan largely lost after its chip dominance faded from the 1980s. (rapidus.inc, datacenterdynamics.com) The target is not memory chips or older car chips. Rapidus says it wants to mass-produce 2-nanometer logic semiconductors in 2027, which puts it in the race for the kind of processors used in artificial intelligence servers and other top-end computing systems. (rapidus.inc, reuters.com) A logic chip factory is one of the most expensive buildings in the world because it needs extreme ultraviolet lithography machines, ultra-clean rooms, and hundreds of process tools that must work in sequence with almost no error. Rapidus says its pilot line in Chitose, Hokkaido, started in April 2025 and includes more than 200 advanced machines. (rapidus.inc, rapidus.inc) Japan is paying because the private sector has not covered the bill on its own. Reuters reported that this latest package lifts government research and development support for Rapidus to 2.354 trillion yen, while Bloomberg reported total government backing is headed toward about 2.6 trillion yen by the end of the current fiscal year. (reuters.com, bloomberg.com) Rapidus is not trying to invent every step from scratch. It has leaned on International Business Machines for 2-nanometer process technology and expanded that relationship in June 2024 to include chiplet packaging, which is the method of combining smaller chip blocks into one package. (ibm.com, research.ibm.com) It also partnered with Imec, the Belgian semiconductor research group whose pilot lines are used by many of the world’s top chip companies to test next-generation manufacturing steps before full production. Imec said in 2022 that Rapidus joined its core partner program to help build the pieces needed for 2-nanometer mass production. (imec-int.com, imec-int.com) The new subsidy is tied to customers as much as machines. Reuters said Japan’s New Energy and Industrial Technology Development Organization will also support chip design projects from Fujitsu and IBM Japan, and Bloomberg reported that Fujitsu is one of the first intended clients Tokyo wants on Rapidus’s line. (reuters.com, bloomberg.com) That customer piece matters because a foundry without designs to manufacture is just a very expensive clean room. In February 2026, Rapidus said it had secured 167.6 billion yen in new private-sector funding from 32 companies, including Canon, Fujitsu, Nippon Telegraph and Telephone, SoftBank, and Sony Group, bringing stated capital and legal capital surplus to 274.95 billion yen. (rapidus.inc, rapidus.inc) Tokyo is chasing two goals at once. One is economic security after years in which leading-edge fabrication concentrated in Taiwan and South Korea; the other is a place in the artificial intelligence supply chain, where advanced logic chips now decide who captures the richest part of the computing market. (reuters.com, datacenterdynamics.com) The bet is still huge and the timetable is still tight. Rapidus says sample production was scheduled for 2025 and mass production for 2027, which gives Japan roughly one product cycle to prove it can turn a government-backed startup in Hokkaido into a real supplier of cutting-edge chips.
