The quake hit under the seabed of the Pacific Ocean about 30 miles off the coast of rural Miyagi Prefecture, or state, the Meteorological Agency said.

The tremor was centered at a depth of about 50 miles, but the agency said there was no dangers of tsunami, or tidal waves, set off by the quake.

The quake was most strongly felt in a town of Nakayama, 192 miles north of Tokyo.

On Sunday, a 4.2 magnitude tremor hit Niigata Prefecture, which faces the Sea of Japan, about 160 miles northwest of Tokyo. There were no reports of injuries or damages.

Japan is one of the world's most earthquake-prone nations as it sits atop four tectonic plates, slabs of land that move across the earth's surface.
