Release plans approved by UN nuclear authority have caused outcry in China and concern for the reputation of Japan’s seafood

Japan is to begin releasing wastewater from the wrecked Fukushima Daiichi nuclear power plant from Thursday, in defiance of opposition from fishing communities, China and some scientists.

The prime minister, Fumio Kishida, said on Tuesday he had asked the plant’s operator, Tokyo Electric Power (Tepco), “to swiftly prepare for the water discharge” in accordance with plans approved by nuclear regulators, adding that the release would begin on Thursday, “weather and ocean conditions permitting”.
