Overview
- A magnitude 5.9 tremor centered in southern Ibaraki struck early Sunday and produced strong shaking across Tokyo and the Kanto region.
- Officials reported dozens of mostly minor injuries with reports clustering around 30–40 people and emergency services responding to elevator entrapments and a ruptured water main in Tokyo's Koto ward.
- Train services across the Kanto area were delayed after the morning quake while Shinkansen bullet services largely continued to operate normally.
- Hours later a separate magnitude 6.0 quake struck offshore Hokkaido near Urakawa at about 40 kilometers depth and caused limited initial damage with no tsunami warning issued.
- Authorities say power outages affecting roughly 460 homes were restored by TEPCO, nuclear regulators reported no anomalies, and the JMA is warning residents to expect aftershocks over the coming week.
