Quake hits northern Japan

TOKYO—A 5.1-magnitude earthquake shook northern Japan late on Wednesday, but there were no immediate reports of damage or casualties and no tsunami warning, the weather agency said.

The quake hit at 10:29 p.m. (1329 GMT) at a shallow point, just offshore of Urakawa, on the southern coast of Hokkaido island, the Japan Meteorological Agency said.

The epicenter is farther north than the March 11 quake on the northeast coast that triggered a tsunami and left 20,000 people dead or missing.
