Tokyo Electronics, a leading semiconductor equipment company, has also completely stopped work at two of its factories in Kumamoto Prefecture. Ebara Seisakusho announced on the same day that it had stopped production at its semiconductor manufacturing equipment plant in Kumamoto Prefecture. Mitsubishi Electric also released news that its two semiconductor manufacturing plants in Kumamoto Prefecture have now completely stopped production. Currently, Japan Post has suspended all post office counter operations in Kumamoto Prefecture. Mitsubishi Chemical Corporation's Kyushu Plant Kumamoto Plant, Bridgestone Kumamoto Plant, Koikeya Kyushu Aso Plant, and Suntory Kyushu Kumamoto Plant have all continued to stop production. Honda suspended the motorcycle production line at the Kumamoto Seisakusho. Aisin Kyushu, a parts manufacturer under Toyota Motor Corporation, temporarily stopped production.
