A major earthquake of magnitude 7.6 has hit Japan’s north-eastern region.
The quake occurred at 23:15 (14:15 GMT) at a depth of 50km (31 miles), about 80km off the coast of the Aomori region, the Japan Meteorological Agency said,
It prompted tsunami warnings which have now been downgraded to advisories, while waves of 40cm (16in) were seen in some places.
Local media reports that some people in the region have been injured, while trains have been suspended as a precaution.
Japan is one of the world’s most earthquake-prone countries, with a tremor occurring at least every five minutes.
Orders were issued for about 90,000 residents to evacuate, according to Reuters news agency.
Japanese public broadcaster NHK quoted a hotel employee in Hachinohe as saying a number of people had been injured.
The government has set up a response office within the prime minister’s crisis management centre and convened an emergency team, chief cabinet secretary Minoru Kihara has said.
“We are making every effort to assess the damage and implement emergency disaster response measures, including rescue and relief operations,” he added.

None were detected either at the disabled Fukushima nuclear power station site, the Japanese authorities told the International Atomic Energy Agency.
Fukushima was damaged when a magnitude 9.0 quake struck off the country’s eastern coast on 11 March 2011.
That quake, the most powerful ever recorded in Japan, triggered a tsunami which swept over the main island of Honshu, killing more than 18,000 people and wiping entire towns off the map.
