Taiwan Semiconductor Manufacturing Co (TSMC) has begun a gradual restart of production at its semiconductor fabrication plant in Kumamoto, Japan, following a significant earthquake that disrupted operations.

The resumption marks a critical step in stabilizing the supply chain for advanced chips produced at the facility, which is part of TSMC’s broader strategy to diversify manufacturing capacity outside of Taiwan.

The news is likely to alleviate concerns among investors and customers regarding potential bottlenecks in the production of cutting-edge logic chips.

TSMC’s Japan facility is pivotal for its long-term expansion plans, and any prolonged downtime would have raised questions about the resilience of the global semiconductor supply chain.

The gradual nature of the restart suggests that full capacity may not be immediately restored, but the move signals that the most critical infrastructure damage has been addressed.

This development comes at a time of heightened scrutiny on TSMC’s operational risks and growth trajectory.
