A powerful Japan earthquake of magnitude 7.4 struck northern Japan on Monday, causing strong tremors across multiple regions and prompting immediate tsunami warnings. The quake hit off the Sanriku coast in Iwate Prefecture, according to the Japan Meteorological Agency (JMA).
The Japan earthquake has raised serious concerns as authorities issued tsunami warnings for Iwate Prefecture along with parts of Hokkaido and Aomori. Officials also warned that coastal areas could experience dangerous wave activity shortly after the seismic event.
Strong Tremors Felt Across Northern Japan
The earthquake in Japan caused intense shaking in several areas, with some locations reporting an upper 5 intensity on Japan’s seismic scale of 0 to 7. The Japan Meteorological Agency confirmed that the epicentre was located off the northeastern coast, triggering immediate emergency alerts.
Following the quake, tsunami waves of up to 3 metres were feared along the affected coastline, leading to widespread caution among residents and authorities.
Tsunami Warning and Evacuation Alerts Issued
After the Japan earthquake, the Japan Meteorological Agency issued a tsunami warning for Iwate Prefecture and advisories for Hokkaido, Aomori, Miyagi, and Fukushima. Coastal residents were urged to evacuate to higher ground as a precaution.
The Japan earthquake has put emergency services on high alert as monitoring continues for potential aftershocks and rising sea levels.
Transport and Infrastructure Impacted
The earthquake also disrupted transport services, with the operator of the Tohoku Shinkansen suspending train operations between Tokyo and Shin-Aomori stations. Passengers were advised to follow safety instructions as inspections were carried out.
Authorities are also checking critical infrastructure, including nuclear power plants, following the earthquake.

Nuclear Plants Under Safety Inspection
Tokyo Electric Power Company confirmed that it is assessing possible impacts at the Fukushima Daiichi and Daini nuclear plants. Meanwhile, Tohoku Electric Power Company is conducting safety checks at the Onagawa and Higashidori nuclear facilities.
The earthquake has renewed attention on nuclear safety measures in seismic-prone regions of Japan.
Historical Context Raises Concerns
The Japan earthquake comes exactly 15 years after the devastating 2011 Tohoku earthquake and tsunami, which caused massive destruction and more than 22,000 deaths. That disaster also triggered the Fukushima nuclear crisis, leading to long-term evacuations and displacement.
Authorities are urging vigilance as the current Japan earthquake continues to develop, with tsunami warnings still in effect in several coastal areas.
Situation Still Developing
Emergency response teams remain active as monitoring continues across northern Japan. The Japan earthquake has prompted widespread alerts, and officials continue to advise residents to stay away from coastal areas until further notice.
