TOKYO—A 5.4-magnitude earthquake struck near the west coast of Japan early Friday, the US Geological Survey (USGS) said.
The earthquake hit at 12:08 a.m. on Friday local time (1508 GMT Thursday), at a depth of 283.5 kilometers (176 miles).
The epicenter was 50 kilometers east of Fukui, Honshu, the USGS statement said.
There were no immediate reports of damage and there were no tsunami warnings in place.
Around 20 percent of the world’s most powerful earthquakes strike Japan, which has developed one of the most sophisticated tsunami warning systems.
