They stressed discharging the water into the ocean will have a significant impact on the global marine environment.

Last week, a similar protest was held by Japanese people in front of the Ministry of Economy, Trade and Industry in Tokyo.

Protesters said on Friday the ocean discharge plan is unacceptable because it poses a significant danger of radioactive contamination and will adversely affect the marine ecosystem and human health.

Some expressed concerns about Japan's economy, which they believe will be affected by a boycott movement in neighboring countries and regions.
