Japan injects JPY150B into Rapidus to push for 2nm production by 2027

Japan’s ¥150B capital injection into Rapidus is less about 2nm timelines and more a geopolitical hedge against overreliance on TSMC. This move pressures ASML and Lam Research to reallocate support resources to Japan while accelerating domestic material suppliers like Shin-Etsu and JSR in EUV photoresist qualification. Yet, Rapidus lacks high-volume manufacturing DNA, and tightening U.S.-Japan-Netherlands export controls will likely inflate its supply chain redundancy costs by over 30%. TSMC and other Taiwan-based foundries won’t alter roadmaps but may deepen client lock-ins with U.S. and European firms. If Rapidus fails to demonstrate yield-ramp-capable pilot lines by late 2027, this investment risks becoming a symbolic gesture—eroding, not enhancing, Japan’s credibility in the global semiconductor ecosystem.
