Japan's chip materials makers reportedly deepen Taiwan ties as AI reshapes supply chains

Japanese material suppliers accelerating investments in Taiwan reflect broader shifts in global semiconductor supply chains. Driven by AI’s demand for advanced nodes, companies like味之素 and 大金 are deepening local partnerships, strengthening Taiwan’s role in critical materials such as silicon wafers and photoresists. This move undermines traditional Japanese and South Korean dominance, reinforcing Taiwan’s strategic position as a key materials hub. From a compliance standpoint, geopolitical tensions are increasing operational risks and costs for firms. Competitors like SK Materials and Shin-Etsu may accelerate investments in mainland China to hedge against supply chain disruptions. Over the next 12–24 months, Taiwan’s material supply chain is likely to become a dual-lock mechanism—technological and geopolitical—positioning it as a pivotal node in global AI chip manufacturing.
