Japan backs Rapidus $4B
Japan approved an additional $4 billion in subsidies to speed Rapidus’s entry into AI chip production, intensifying national efforts to build domestic semiconductor capacity. The funding aims to accelerate local fabrication as countries compete to secure chip supply for data‑centre and edge AI demand. (x.com)
Japan just added 631.5 billion yen, about $4 billion, to Rapidus, the chip company it set up in 2022 to try to put leading-edge semiconductor production back on Japanese soil. The approval came on April 11 and lifts government research support for Rapidus to roughly 2.354 trillion yen. (reuters.com) Rapidus is building its first factory, called Innovative Integration for Manufacturing 1, in Chitose on Japan’s northern island of Hokkaido. The company says that site is meant to make logic chips at 2 nanometers or smaller, which is the class of chips used as the brains inside servers and advanced devices. (rapidus.inc) A logic chip is the part that does the computing, not the memory that stores data. When governments talk about artificial intelligence chip supply, they usually mean more of these logic chips for data centers, because training and running artificial intelligence models burns through huge amounts of compute. (rapidus.inc) Japan is spending this heavily because it lost ground in the most advanced chip race for years while Taiwan Semiconductor Manufacturing Company and Samsung pulled ahead. Rapidus was created with backing from eight Japanese companies after executives concluded that the Taiwan Semiconductor Manufacturing Company plant coming to Kyushu would not give Japan a domestic path to 2 nanometer production. (rapidus.inc) The company is not starting from scratch on the core process. Rapidus signed a deal with International Business Machines in December 2022 to turn International Business Machines’ 2 nanometer technology into something that can be manufactured at scale, and International Business Machines later said its factory software was already running at Rapidus’s IIM-1 site from April 2025. (ibm.com) Rapidus says it hit a key checkpoint on July 18, 2025, when it began prototyping 2 nanometer gate-all-around transistors at IIM-1 and confirmed electrical characteristics on those wafers. The company still says the target is mass production in 2027, which is an extremely fast schedule for a brand-new manufacturer. (rapidus.inc) That speed is why the subsidy is aimed at research and development rather than just pouring concrete. Reuters reported that the new money is meant to accelerate Rapidus’s development work, and Jiji said the funds will be used mainly for refining prototypes as the company pushes toward fiscal 2027 production. (reuters.com) (jiji.com) The gamble is that Japan would rather overpay now than stay dependent forever on overseas fabs for the most advanced processors. If Rapidus can get from prototype wafers in Hokkaido to reliable 2 nanometer output in 2027, Japan gets more than a factory: it gets a domestic seat at the table in the artificial intelligence hardware race.
