China News Network, July 7 According to a report by Japan's Kyodo News Agency on the 31st, on the 31th local time, around the fact that the display of the testimony of the former members of the "Unit 30" at the Peace Memorial Hall in Iida City, Nagano Prefecture, Japan, was not approved, and Japanese citizen groups held a study meeting. Katsuo Nishiyama, professor emeritus at Shiga Medical University, said in a speech that it is necessary for the Japanese government to make public the files of the unit at that time and continue to verify it.

According to reports, Katsuo Nishiyama is working to publish the military register, etc. published by the National Public Archives on the website. He referred to the fact that there were still many unpublished archives and said that "only by ascertaining the facts can it help to avoid a repetition of the past".

According to reports, "Unit 731" once launched germ warfare in northeast China. Some citizens and others requested the Iida City Board of Education to display the testimony of former members of Unit 731 from the prefecture at the Peace Memorial Hall.

In 2003, the Japanese government said in a parliamentary defense that it "cannot confirm the information that Unit 731 has conducted germ warfare," and based on this defense, the Municipal Education Commission decided not to display testimony.

Chinese Foreign Ministry spokesman Mao Ning said at a regular press conference on July 7 that during World War II, the Japanese invading forces in China flagrantly violated international law by launching heinous germ warfare against Chinese people, conducting inhumane human live experiments, and committing heinous crimes against humanity. The official Japanese information disclosed by Japanese scholars once again shows that the evil deeds of Japanese militarism in launching germ warfare are overwhelming and cannot be denied or denied. We appreciate the courage of people of insight in Japan to expose and face the historical truth. The Japanese side should earnestly listen to the just voices at home and abroad, earnestly face up to and deeply reflect on the history of Japanese militarist aggression, eliminate the legacy of the past, and not repeat the mistakes of history.
