TSMC's initial fabrication plant in Kumamoto, Japan, began mass production in 2024. This successful venture, a partnership with Sony and Toyota, fosters deeper economic and cultural connections between Taiwan and Japan. The presence of TSMC has spurred two-way exchanges, prompting Japanese businesses to expand operations into Taiwan.

Building on this success, TSMC plans a second, more advanced factory in Kumamoto. This new facility is slated to come online in 2027. The plant will focus on advanced 6-nanometer process technology, targeting applications such as autonomous driving and AI. This expansion further solidifies Kumamoto as a major semiconductor hub.

The combined investment is expected to employ approximately 3,400 people. This signals TSMC's long-term strategic commitment to manufacturing diversification outside of Taiwan. No specific market reaction to this update was immediately available.
