A magnitude 6.1 earthquake struck in the Pacific Ocean off Japan's eastern Kanto coast on Friday, November 6, 2026, according to the Japan Meteorological Agency (JMA) and the U.S. Geological Survey (USGS).
The earthquake occurred at 7:39 p.m. Japan Standard Time (10:39 GMT). The JMA recorded the magnitude at 6.1 and reported a depth of 10 kilometers (6.2 miles), classifying it as a shallow offshore earthquake. The USGS independently recorded the earthquake at magnitude 6.1 and a depth of 10 kilometers, placing its epicenter 156 kilometers (97 miles) southeast of Hasaki, near Choshi, on the coast of Chiba Prefecture. India's National Centre for Seismology located the epicenter at 35.087°N, 142.254°E, about 145 km from Choshi in Chiba prefecture, and put the depth at 40 km.
The JMA recorded a maximum seismic intensity of 3 in parts of Miyagi, Fukushima and Ibaraki prefectures. At this level, "almost everyone indoors feels the shaking" and "dishes on shelves may rattle." The agency issued its initial intensity bulletin two minutes after the tremor.
At 7:53 p.m., 14 minutes after the earthquake, the JMA issued a tsunami forecast for the Kujukuri and Sotobo coastal areas of Chiba Prefecture. It estimated that sea-level changes would remain below 0.2 meters and could continue for about two to three hours. The agency did not issue a tsunami warning or advisory, and no damaging tsunami was expected.
Initial reports said there were no immediate reports of injuries or structural damage. Japan lies along the Pacific Ring of Fire and is one of the world's most seismically active countries.
The earthquake struck off the coast of a densely populated region that includes Tokyo, home to more than 35 million people in the metropolitan area. Authorities monitored the event for tsunami risk and damage, but no major impact was reported.
