Site of"Unit 731"of the Japanese Army that Invaded China

"Manchu Unit 731"was a special troop set up in China under the imperial edict.In 1935,the unit set up the biological weapon research and test base in Pingfang and a biological warfare command of the Japanese Army in the Southeast Asia.

In the base,which was referred to as the "den of cannibals",Unit 731 engaged in germ weapon research by conducting cruel vivisection.According to historical documentation,just between 1939 and August of 1945 alone at least 3,000 anti-Japanese and anti-Manchukuo fighters from home and abroad and innocent civilians were maimed and killed as vivisection subjects.

In August 1945,Japan lost the war and surrendered.In order to cover up its heinous atrocities,Unit 731 carried out large-scale destruction and sabotage to the facilities in this area.Today 23 sites are listed as the key sites for protection to testify to the crimes.
