Kazuyoshi Sato, co-director of KOREUMI — a Japanese citizens' group to condemn pollution of the ocean — urged the Japanese government to abide by its promise no disposal of nuclear-contaminated water would be carried out without the understanding of the parties involved. Sato made the demand during a speech at a rally in front of the Prime Minister's official residence in Tokyo on Friday.

Hundreds of Japanese gathered on Friday to protest the Japanese government's plan to discharge nuclear-contaminated water from the Fukushima Daiichi nuclear power plant into the ocean.

Protesters handed a petition to the representatives of the Japanese government and the Tokyo Electric Power Company, requesting the government to halt the process.
