The epicentre of the quake was at a relatively shallow depth of 11km (7 miles) below the surface. Shallow quakes potentially cause more damage but most of Friday's damage appears to be minor or localised.

The agency said there was no danger of a tsunami from the inland temblor.

Suminori Sakinada, a local government official, told Agence France Presse: "We felt fairly strong jolts, which I think were the biggest in years, but we have not seen any damage or things falling".
Bullet train services have been suspended in the area and nearly 40,000 homes were believed to be temporarily left without power as the quake knocked out power lines.

NHK said switched-off nuclear reactors in the region were not affected.
Japan sits on the edge of four tectonic plates so earthquakes and volcanic eruptions are fairly commonplace but strict building regulations mean strong tremors rarely do damage to modern buildings.
