Mitsubishi, Honda and Daihatsu Halt Production After Kumamoto Earthquake

When a single seismic event can idle plants across Toyota, Nissan, Mitsubishi, Honda, and Daihatsu simultaneously, it underscores just how geographically concentrated Japan's manufacturing base remains. Kumamoto is not a peripheral location — it sits within a region that feeds critical components and final assembly for global model lines, so stoppages there ripple outward fast. The human toll of 18 deaths is the real story, but for anyone tracking supply chains after the lessons of 2011, the breadth of shutdowns across competing manufacturers signals how little redundancy exists when a region goes down. This is the kind of event that quietly reshapes procurement conversations for years afterward.
