A powerful earthquake with a magnitude of 7.2 struck off the eastern coast of Iwate in northern Japan on Thursday, June 25, 2026, according to the Japan Meteorological Agency (JMA). The agency upgraded the initial reading from 6.9 and confirmed there was no danger of a tsunami. The quake occurred at a depth of approximately 50 kilometres (30 miles) during the morning rush hour, mildly shaking Tokyo as well.
Quake Details and Response
The Japan Meteorological Agency reported that the earthquake's epicentre was off the coast of Iwate prefecture. The US Geological Survey recorded a magnitude of 6.9. This region has experienced repeated strong earthquakes in recent months, including one that triggered a week-long mega-quake caution advisory in December 2025.
Prime Minister Sanae Takaichi addressed the nation, stating that her government's emergency team is "putting people's lives first" while assessing information and preparing for relief operations if needed. She urged residents in affected areas to remain cautious of possible aftershocks. Top government spokesperson Minoru Kihara confirmed there were no immediate reports of injuries or damage.
Impact on Communities and Infrastructure
Tomoko Nagane, a primary school principal in Hashikami, Aomori prefecture, told NHK that she was driving when the quake alert activated and felt moderate sideways shaking. Children at the school were safe, though some were crying in fear. Classes were cancelled for the day, and all children returned home safely.
NHK journalists in strongly-hit towns such as Sendai and Morioka reported feeling shaking for a couple of minutes but observed no damage. Footage showed people commuting as usual. The East Japan Railway Co suspended some bullet trains and local lines in the northeastern region for safety checks.
No Tsunami Advisory Issued
The JMA did not issue any tsunami warning or advisory, as the earthquake's depth and location did not pose a tsunami risk. The agency continues to monitor seismic activity in the area.
