This is a list of earthquakes in Japan with a magnitude of 7.0 or above or which caused significant damage or casualties. As indicated below, magnitude is measured on the Richter magnitude scale (ML) or the moment magnitude scale (Mw), or the surface wave magnitude scale (Ms) for very old earthquakes. The present list is not exhaustive and reliable and precise magnitude data is scarce for earthquakes that occurred prior to the development of modern measuring instruments.

This megathrust earthquake's hypocenter was reported to be off the Oshika Peninsula, the east coast of Tōhoku[72] It was the strongest to hit Japan and one of the top five largest earthquakes in the world since seismological record-keeping began.[73][74][75] It was followed by a tsunami with waves of up to 10 m (33 ft).[73] The disaster left thousands dead and inflicted extensive material damage to buildings and infrastructure that led to significant accidents at four major nuclear power stations. 2,814 people missing[76]
