Saturday's quake cracked walls, shattered windows and set up a landslide close to the epicenter.

National television said 104 people were injured, but that there were no reports of any deaths.

Hundreds of thousands of buildings reported temporary power losses.

Most supplies have since been restored, but many homes remained without water.

Trains were halted over huge areas of northeastern Japan on Sunday.

Buildings also shook in the Japanese capital of Tokyo, located hundreds of miles away.

No irregularities were reported that any nuclear facilities on the earthquake appears not to have caused a repeat off the 2011 tsunami, which devastated the Pacific coastline and killed nearly 20,000 people.

But the Japan Meteorological Agency still issued a warning of aftershocks in the coming days.
