According to the Japan Meteorological Agency, the quake originated in the Pacific Ocean at a depth of approximately 10 kilometres, with its epicentre located offshore. Authorities warned that tsunami waves as high as three metres could reach parts of the northern coastline, including Iwate Prefecture, Aomori Prefecture, and Hokkaido.
Japanese Prime Minister Sanae Takaichi confirmed the formation of an emergency response task force and urged residents in affected coastal areas to evacuate immediately and move to higher ground.
State broadcaster NHK reported ships leaving ports in anticipation of incoming tsunami waves, while evacuation alerts flashed across television screens warning residents to “Evacuate immediately.” Rail services, including bullet trains in northern regions, were also suspended as a precautionary measure.
The quake registered an “upper 5” on Japan’s seismic intensity scale, strong enough to make standing and movement difficult, and capable of causing structural damage to weaker buildings.
Japan, located along the seismically active “Ring of Fire,” is among the most earthquake-prone countries in the world, experiencing frequent tremors and some of the most powerful earthquakes globally.
Authorities also confirmed monitoring of nuclear facilities in the affected regions, including shutdown plants operated by regional utilities, as inspections were launched to assess potential damage and tsunami impact.
Emergency operations remain ongoing as officials continue to evaluate the situation and monitor possible aftershocks and tsunami activity along Japan’s northeastern coastline.
