A powerful earthquake has rocked the Japanese city of Sapporo, the capital of the northern Hokkaido prefecture.
The magnitude 6.7 quake struck 112 kilometers south of the city at an approximate depth of 32 kilometers, according to the US geological service (USGS).
The earthquake caused a landslide that engulfed houses early on Thursday, injuring and trapping a number of people and cutting power in several areas.
A landslide along a long ridge in the rural town of Atsumi could be seen in aerial footage from public broadcaster NHK.
Some 10 people had been taken to hospital with injuries, one of them serious, but no early reports of deaths.
The Japan Meteorological Agency (JMA) said the quake which struck at about 3:08am on Wednesday, posed no threat of a tsunami.
Prime Minister Shinzo Abe told reporters his government had set up a command center to coordinate relief and rescue.
