A strong earthquake struck off the coast of Fukushima, Japan, on Saturday, just weeks before the 10-year anniversary of the deadly 2011 tsunami

The 7.3-magnitude quake was felt strongly in Tokyo, but a tsunami warning has not been issued.

There are reports of about 50 people injured, officials say, and almost one million homes are without power.

The quake struck near the epicentre of a 2011 earthquake which triggered a tsunami and killed over 18,000 people.

That tsunami caused a nuclear accident at the Fukushima Daiichi Nuclear Power Plant - the world's most severe nuclear accident since the Chernobyl disaster in 1986.

Saturday's quake hit at 23:08 local time (14:08 GMT) at a depth of 60km (37 miles) in the Pacific, off Japan's eastern coast, JMA said. Aftershocks have continued to hit the region since.

Chief Cabinet Secretary Katsunobu Kato told reporters that evaluations were under way, including of the region's nuclear plants.

"Casualties and structural damage are being assessed," he told a press conference, but added that parts of the high-speed bullet train network had been suspended because of power outages.
