Kumamoto earthquake halts Toyota, Nissan and semiconductor factories

Kumamoto earthquake Toyota production halt semiconductor plant shutdown auto supply chain disruption Japan industrial impact

A magnitude‑7.1 earthquake struck Kumamoto Prefecture in southwestern Japan on 28 July 2026, killing at least 34 people and leaving around 48,000 households without power. The tremor damaged infrastructure and disrupted supply‑chain logistics across the region.

Automobile manufacturers responded by suspending production. Toyota halted output at its Miyata, Kanda and Kokura plants in Fukuoka and at a plant in Aichi until early August, citing safety, supplier and logistics concerns. Nissan partially suspended activity at its Kyushu assembly sites but said Australian shipments should not be affected. Honda stopped work at its Kumamoto motorcycle factory until 31 July for repairs. Supplier Aisin began test production of components at its Kumamoto facility and is gradually restarting operations.

Semiconductor firms also paused work. Renesas Electronics stopped production at its two Kumamoto chip plants, while Sony Semiconductor Solutions announced a phased restart of its image‑sensor factory from 4 August, targeting normal capacity by mid‑August. TSMC briefly evacuated workers from its Kumamoto wafer fab but resumed operations the same day. Other chip makers, including Tokyo Electron, reported equipment checks and gradual resumption.

The shutdowns affect a dense industrial cluster that hosts thousands of automotive and semiconductor companies, raising concerns about broader supply‑chain shortages for vehicles and electronic components worldwide.
