Japan has begun considering a rescue plan for its domestic fisheries after China reacted to the discharge of treated radioactive water from the crippled Fukushima No. 1 nuclear power plant by imposing a blanket import ban on Japanese fishery products, officials have said.

The government seeks to mitigate the Chinese move's negative impact on the fishery industry while continuing to urge China to lift the measure it deems "not based on science," the officials said Friday.

Japan's seafood exports to China stood at around ¥160 billion ($1 billion) in 2022, some 40% of total outbound shipments in value terms, according to government data.
