The water was used to cool the Fukushima nuclear plant which went into meltdown in 2011.
Japan is to release treated radioactive water from the destroyed Fukushima nuclear plant into the sea, media reports say.
It follows years of debate over how to dispose of the liquid, which includes water used to cool the power station hit by a massive tsunami in 2011.
Environmental and fishing groups oppose the idea but many scientists say the risk it would pose is low.
The government says no final decision has been made.
The release of more than a million tonnes of water, which has been filtered to reduce radioactivity, would start in 2022 at the earliest, according to Japanese media outlets including national dailies the Nikkei and the Yomiuri Shimbun.
The water would be diluted inside the plant before release so it is 40 times less concentrated, the Yomiuri Shimbun said, with the whole process taking 30 years.
An official decision could emerge by the end of this month, said Kyodo news agency.
