A 6.7-magnitude earthquake occurred off northern Japan on Friday (December 12, 2025), the weather office said, days after a 7.5-level tremor in the same region injured at least 50 people.

The Japan Meteorological Agency (JMA), upgrading its initial estimated magnitude of 6.5, also warned that tsunami waves of up to one metre (three feet) could hit the northern Pacific coastline.

The United States Geological Survey (USGS) also said that the quake measured 6.7 and was 130 kilometres off the city of Kuji in Iwate prefecture on the main island of Honshu.

Broadcaster NHK said that the level of shaking was less than the bigger tremor late Monday which knocked items off shelves, tore apart roads, smashed windows and triggered tsunami waves of up to 70 centimetres.
