A 6.2-magnitude earthquake struck Japan on Friday.
Officials said there was no preliminary damage and no tsunami threat.
The earthquake struck Ishikawa prefecture near the central-west coast of the main Japanese island of Honshu, according to the US Geological Survey's earthquake information center.
Japan's Kyodo News agency reported that there was nothing concerning at a nearby nuclear power plant in Niigata Prefecture.
Japanese officials said there could be small waves but no tsunami danger.
Japan is one of the world's most earthquake-prone nations. A massive 2011 quake in the country's northeast caused a devastating tsunami and nuclear plant meltdown that still reverberates today.
