A day after an aftershock hit northern Japan, authorities have restored power to three nuclear plants hit by the latest tremor.
Thursday night’s 7.1-magnitude earthquake left four people dead and 141 injured in the Miyagi Prefecture.
Experts say there are signs of water leakage at the Onagawa station, however they say the radiation levels are well below the legal limit and there is no immediate danger.
The aftershock follows a March 11 earthquake and tsnumai that crippled the Fukushima nuclear power plant, leaking radioactive iodine into the sea.
That has sparked concerns about the safety of Japanese food products.
In Hong Kong, officials have been stepping up checks on Japan-sourced goods and are issuing licences to the businesses that sell them.
