Japan’s government adopted an interim plan Tuesday that it hopes will win support from fishermen and other concerned groups for a planned release into the sea of treated but still radioactive water from the wrecked Fukushima nuclear plant. The government decided in April to start discharging the water into the Pacific Ocean in the spring of 2023 after building a facility and compiling release plans under safety requirements set by regulators. The idea has been fiercely opposed by fishermen, residents and Japan’s neighbours including China and South Korea.
