While the Nazi’s in World War Two were famously known for human experiments, they certainly weren’t the only ones performing them. The Japanese conducted many as well on POWs and Chinese civilians. Unit 731 opened in Japan-occupied China in 1938 and is responsible for about 3,000 lives being lost.

They would inject people with anthrax and the plague, and would even put bodies in pressure chambers until their bodies literally exploded. Interestingly enough, after the war ended the doctors who performed the experiments were given immunity by the US in exchange for the information that was found through doing them.
