At least six people are dead and more than 140 injured after a powerful earthquake struck northern Japan, triggering landslides.
The 7.2-magnitude quake was centred on Iwate - a rural mountainous region on Japan's main island, Honshu.
Military helicopters are taking in supplies and flying the injured to hospitals. A landslide at a hot spring reportedly buried seven people.
And a small amount of radioactive water was leaked at a nuclear power station.
But officials said there was no danger to the public from the minor spillage at the facility in Fukushima.
Prime Minister Yasuo Fukuda said: "Our most important task is to save as many lives as possible, and we are doing the best we can."
