Japan’s 7.1-magnitude quake halts Toyota, Renesas, TSMC plants in Kumamoto
A 7.1-magnitude earthquake hit Kumamoto Prefecture in Japan on July 28, 2026, forcing Toyota to halt production at three Kyushu plants — Miyata, Kanda, and Kokura — through July 31. The Miyata plant alone produces 430,000 vehicles annually. Renesas suspended operations at two Kumamoto fabs due to structural damage, while TSMC evacuated staff at its JASM facility before confirming structural safety and beginning gradual restart. Honda extended its Kumamoto motorcycle plant suspension to July 31; Sony halted semiconductor operations in Kumamoto but found no major damage in Nagasaki, Oita, or Kagoshima. Nissan kept its Fukuoka plant running but is closely monitoring supplier networks. Kyushu accounts for ~12% of Japan’s auto component output and >30% of domestic semiconductor wafer production.
