“Unit 731″ was a covert biological and chemical weapons research unit of the Imperial Japanese Army that conducted lethal human experimentation on thousands of captives, many including Chinese and Korean civilians. Experiments included vivisection (surgery on live, conscious subjects), forced infections with lethal diseases like anthrax and plague, frostbite testing, and chemical weapons effects testing.
