Why did a large supermarket in Seoul put up a boycott slogan on Japanese goods?

On April 15, local time, a large supermarket in Seoul, South Korea, hung many "Boycott Japanese Products" slogans in response to the Japanese government's decision to discharge Fukushima nuclear wastewater into the sea.

In response, all walks of life in South Korea protested. South Korea’s Ministry of Foreign Affairs previously summoned Japan’s ambassador to South Korea, Koichi Aohoshi, to lodge a solemn protest. South Korean President Moon Jae-in said in this regard: "I am deeply concerned." South Korean Prime Minister Ching Sye-kyun posted on social media that Japan's move is an "irresponsible decision"; if Japan insists on discharging nuclear wastewater into the sea, it will be " Once again making a historical mistake."

South Korea’s Ministry of Oceans and Fisheries announced that it plans to strengthen origin traceability supervision of Japanese seafood and will increase law enforcement.

Korean Central News Agency: The decision to discharge nuclear wastewater into the sea exposed Japan's "shameless and gangster nature"

April 15, The Korean Central News Agency published a commentary article stating that Japan currently plans to bring a new catastrophe to humanity that is being baptized by the global new coronavirus epidemic. Comments said that on the 13th, the Japanese government decided to discharge a large amount of nuclear wastewater produced by the Fukushima nuclear power plant accident into the sea, despite strong opposition from the international community. This is an intolerable crime that seriously threatens human health and safety and the ecological environment. It is another example of Japan's shameless and gangster nature.

Comments warned that if the Japanese government discharges nuclear sewage, known as radioactive nuclear waste, into the sea, a large amount of hazardous substances contained in it will spread from the coast of Fukushima, where the currents are faster, to the Pacific Ocean within dozens of days. Most of the waters will not only destroy the ecological environment of the blue ocean, the common wealth of mankind, but also cause serious danger to the health and survival of people in coastal areas. What's more, for North Korea, which is separated from Japan across the sea, this is a major issue related to the life and safety of the North Korean people.
