Japan tops up Rapidus
Japan approved a large additional subsidy for Rapidus, stepping up state support for domestic advanced‑chip capacity as countries race to secure semiconductor supply chains. The move—reported as part of a broader industrial‑policy push—signals that governments are shifting from tax incentives to direct funding of chip development and production. (thenews.com.pk)
Japan just added another ¥631.5 billion, about $4 billion, to Rapidus, the state-backed chipmaker trying to build cutting-edge logic chips in Hokkaido, and that pushes its research support to roughly ¥2.354 trillion. (rapidus.inc) Rapidus is not an old industrial giant getting a rescue check. It was created in 2022 to rebuild a part of Japan’s chip industry that had fallen far behind Taiwan Semiconductor Manufacturing Company and Samsung in the most advanced chips. (rapidus.inc) (research.ibm.com) The chips Rapidus wants to make are 2-nanometer logic chips, which are the brains used for artificial intelligence servers, phones, and data centers. “2 nanometer” is a generation label for very dense, very fast chips, not a ruler measurement you can see with your eye. (research.ibm.com) (rapidus.inc) Japan picked Rapidus because advanced chip factories now cost so much that private money alone often will not build them. Bloomberg reported that Tokyo expects to put a total of ¥2.6 trillion into Rapidus by the end of the current fiscal year while the company hunts for about ¥3 trillion more from private investors. (bloomberg.com) This round is tied to actual work, not just a patriotic promise. Reuters said the new money is meant to speed research and development, and Bloomberg said part of it will bankroll Rapidus work for Fujitsu, which Tokyo hopes can become one of the first real customers. (bloomberg.com) Rapidus is borrowing technology instead of inventing everything from scratch. It has worked with International Business Machines since December 2022 on 2-nanometer process technology, and in June 2024 the two companies expanded that tie-up to chiplet packaging, which is the method of linking several small chips together inside one package. (rapidus.inc) (newsroom.ibm.com) The factory at the center of the bet is Rapidus’s Innovative Integration for Manufacturing site in Chitose, Hokkaido. Rapidus said its pilot line started in April 2025, and on April 11, 2026, it opened a new Analysis Center next door to test materials, reliability, and electrical performance before mass production. (rapidus.inc 1) (rapidus.inc 2) The schedule is aggressive. Rapidus says it is aiming for mass production in 2027, and Reuters reported that the new subsidy is meant to help it hit that timetable for advanced domestic production. (rapidus.inc) Japan is not betting on one model alone. While Rapidus chases the frontier at 2 nanometers, Taiwan Semiconductor Manufacturing Company’s Japan Advanced Semiconductor Manufacturing unit in Kumamoto is building more mature chips for cars and industrial gear, with a second fab scheduled to begin operation by the end of 2027. (pr.tsmc.com 1) (pr.tsmc.com 2) That split tells you what Tokyo is doing with the checkbook. One lane brings in foreign manufacturing capacity that Japan can use now, and the other lane tries to recreate a domestic champion for the chips that will power the next wave of artificial intelligence hardware.
