Nearly a decade after the Fukushima nuclear disaster, Japan’s government has decided to release over one million tonnes of contaminated water into the sea, media reports said on Friday, with a formal announcement expected to be made later this month.

The decision is expected to rankle neighbouring countries like South Korea, which has already stepped up radiation tests of food from Japan, and further devastate the fishing industry in Fukushima that has battled against such a move for years.

The disposal of contaminated water at the Fukushima Daiichi plant has been a longstanding problem for Japan as it proceeds with an decades-long decommissioning project. Nearly 1.2 million tonnes of contaminated water are currently stored in huge tanks at the facility.

The plant, run by Tokyo Electric Power Company Holdings Inc , suffered multiple nuclear meltdowns after a 2011 earthquake and tsunami.

On Friday, Japan’s industry minister Hiroshi Kajiyama said no decision had been made on the disposal of the water yet, but the government aims to make one quickly.

“To prevent any delays in the decommissioning process, we need to make a decision quickly,” he told a news conference.

He did not give any further details, including a time-frame.
