What is the earthquake risk like in Japan in 2026?

Tokyo runs the densest drill culture, early-warning phone alerts, and skyscraper engineering, yet soft-soil basins and crowded stations still shape preparedness. Osaka and Kansai share the same national codes with their own fault stories. Sendai and wider Tohoku carry the lived memory of the 2011 earthquake and tsunami, so coastal evacuation routes matter as much as indoor Drop, Cover and Hold. Kobe rebuilt after the Hanshin earthquake; ask about seismic standards when you view older stock.

Tsunami risk concentrates on Pacific and some inland-sea coasts. Inland apartments still need furniture straps even when tsunami maps look distant. Flood and typhoon maps remain a separate checklist: Flood risk and Typhoon risk.
