Scientists found no trace of radiation either in the water or in sea creatures. But motivated by nationalist politics, China has banned all Japanese seafood.
The treated water release was decided after confirming the "safety, reputational damage measures, and continued support" from TEPCO., said PM Fumio Kishida.
Praising the IAEA report, the South Korean activists asked for information sharing as the discharge begins and that Seoul's experts be allowed to monitor it.
Japan's plan for releasing treated water from Fukushima Daiichi meets international safety standards. China can't say the same about its own tritium releases.
China's Qinshan No 3 Nuclear Power Plant in Zhejiang Province emits roughly 143 trillion Bq of tritium, some 6.5 times more than planned at Fukushima Daiichi.
In Japan, tritium comes 10 times more in rainfall than would be released at Fukushima Daiichi. China and South Korea release far more of it.
The scientific data contradicts the critics, as Japan shares facts and details of its Fukushima cleanup plans with foreign governments and international media.
Baseless rumors holding up release of the safe, treated water are only obstructing the far more important job of decommissioning the damaged nuclear reactor itself.
Political activists and the media continue to nurture a psychology of anxiety even 10 years after the crisis.
Fukushima Innovation Coast Framework has plans to help restore economies in disaster-afflicted regions with cutting-edge industries. Here's a closer look.
"It is important to continue providing accurate explanations" to correct misconceptions about Fukushima, says University of Tokyo Professor Naoya Sekiya.
Despite following China in restricting Japanese seafood imports, three Russian trawlers were found to be operating in waters near the Fukushima nuclear plant.
