Powerful 6.9-Magnitude Earthquake Strikes Northern Japan, No Tsunami Warning Issued

The Japan Meteorological Agency said the epicenter was 50 kilometers deep off the coast of Iwate Prefecture

Published June 25, 2026

TOKYO, Japan — June 25, 2026 — A powerful magnitude 6.9 earthquake struck off the coast of northern Japan on Thursday morning, shaking buildings across a wide area, including parts of Tokyo, but authorities reported no immediate casualties and issued no tsunami warning.

According to the Japan Meteorological Agency (JMA), the earthquake occurred off the coast of Iwate Prefecture on Japan’s main island of Honshu at a depth of approximately 50 kilometers. The U.S. Geological Survey also recorded the quake at magnitude 6.9.

The strongest shaking was recorded in parts of Aomori Prefecture, where the tremor reached an upper six on Japan’s seven-level Shindo seismic intensity scale. At that intensity, people often struggle to remain standing, and unsecured furniture can topple.

Despite the quake’s strength, authorities said there were no immediate reports of deaths or serious injuries. Chief Cabinet Secretary Minoru Kihara stated that the government was continuing to assess the situation while monitoring for possible damage.

The earthquake temporarily disrupted transportation across northeastern Japan. Several Shinkansen bullet train services were suspended for safety inspections before operations gradually resumed. Public broadcaster NHK reported that traffic signals and major roadways remained operational in affected areas.

Officials also confirmed that no abnormalities were detected at nuclear facilities, including monitoring systems linked to power plants in northern Japan.

Prime Minister Sanae Takaichi directed government agencies to coordinate closely with local authorities and urged residents in affected regions to remain vigilant for potential aftershocks.

Japan sits along the Pacific “Ring of Fire,” one of the world’s most seismically active regions. The country experiences hundreds of earthquakes annually and remains highly sensitive to seismic threats following the devastating 2011 earthquake and tsunami disaster.

While Thursday’s earthquake caused concern across northern Japan, early assessments suggest that damage was limited and that the country’s extensive earthquake preparedness systems helped minimize disruption. Authorities continue to monitor the situation as aftershocks remain possible in the coming days.
