The explosion was a premeditated and deliberate massacre perpetrated by the Japanese imperialists consistent with their policy to exterminate the Korean nation, the article says, and goes on:

The Japanese reactionaries tried to avenge their defeat by killing more Koreans. So, they orchestrated the unprecedented case. They schemed to keep the case in mystery, claiming that it was "an inevitable accident" by a mine. The Japanese government refused to confirm the number of the dead by the explosion and their names and addresses and even opened to the public the much diminished death toll. The case is an unpardonable crime against humanity in view of international law and humanitarianism and in the light of the reason why Koreans were taken to Japan.

Japan's history since then has been characterized by moves to stage a comeback to Korea. Japan seeks to exterminate Koreans before anything else in a bid to put Asia under its control and realize the "greater east Asia co-prosperity sphere." This is its invariable guidelines for aggression.

The Korean people can and will never forget the crime-woven history of the Japanese imperialists.

They will never pardon the crimes Japan committed by forcibly drafting millions of Koreans to exploit them and massively killing many of them after its defeat.
