A 5.3-magnitude earthquake has hit the Japanese prefecture that is home to the nuclear power plant crippled in the March 2011 earthquake and tsunami.
The US Geological Survey says the quake struck early Friday at a depth of about 22 kilometres under Fukushima Prefecture and about 177 kilometres northeast of Tokyo.
The Pacific Tsunami Warning Center did not issue an alert.
Japanese Prime Minister Shinzo Abe on Thursday ordered TEPCO to scrap all six reactors at the Fukushima Dai-ichi plant and concentrate on tackling pressing issues like leaks of radioactive water.
