Unit 731

Definition

Unit 731 was a covert biological and chemical warfare research unit of the Imperial Japanese Army during World War II, responsible for horrific human experimentation and war crimes against both military personnel and civilians. The unit conducted gruesome experiments, including vivisection without anesthesia, on live human subjects, primarily Chinese prisoners of war and civilians, leading to immense suffering and death. The activities of Unit 731 exemplified the brutal atrocities committed by the Axis powers during the war.
