Taiwan-Japan AI tech forum seeks closer partnerships

The Taiwan-Japan AI forum reveals deeper anxieties about advanced-node capacity. While IBM has proven 2nm feasibility, Rapidus’s real bottleneck in Hokkaido isn’t tools or IP—it’s yield ramping, which demands an ecosystem Japan lacks: advanced packaging, EDA talent, and high-purity process control. If Tokyo fails to push 2nm yields above 60% within 18 months, its 'de-Taiwanization' narrative collapses into political theater. The U.S. is leveraging Japan to fill logic-chip gaps, but without TSMC-style vertical integration, costs for AI accelerators will rise. Over the next 24 months, expect intensified U.S.-Japan subsidies for materials and inspection equipment—but without a dense East Asian supply cluster, Nvidia and AMD will remain strategically tethered to Taiwan, China’s manufacturing dominance.
