Japan is set to release treated radioactive water from the Fukushima nuclear plant into the Pacific Ocean, a move that has been met with opposition from neighbouring countries.
The water, which has accumulated since the 2011 tsunami that damaged the plant, will be released over 30 years after being filtered and diluted. The water contains tritium and carbon-14, both of which emit low levels of radiation and may impact marine biodiversity.
Japan is an island country in East Asia. It is situated in the northwest Pacific Ocean and is bordered on the west by the Sea of Japan, extending from the Sea of Okhotsk in the north toward the East China Sea, the Philippine Sea, and Taiwan in the south.
