Japan's Meteorological Agency says a small tsunami reached the Pacific coast of northern Japan Sunday after a strong earthquake hit the region that was heavily damaged by a huge quake and tsunami in March.

The agency said the port town of Ofunato in Iwate prefecture saw a 10-centimeter tsunami before a warning was lifted. The agency had predicted a wave of up to 50 centimeters.

The agency issued the tsunami warning after an earthquake with a magnitude of 7 hit Sunday morning in the Pacific Ocean off the coast of Japan's main island of Honshu.

There are no immediate reports of injuries or damage from the quake.

The March earthquake and tsunami devastated much of coastal northeastern Japan, and left some 23,000 people dead or missing. The twin disasters also touched off a nuclear crisis at a badly damaged nuclear facility in Fukushima.
