In 1931, the Japanese imperial army staged the September 18 Incident –-- a false flag operation created to validate its intrusion of China.
Eleven months later, Shiro Ishii arrived in Northeast China, where he established the Kwantung Armys Epidemic Prevention and Water Purification Department, which would later become recognized just as Unit 731.
In the guise of epidemic prevention and water purification work, it conducted experiments on living humans as part of a program to establish biological weapons.
A museum in Harbin consists of proof of the dreadful criminal activities Unit 731 devoted throughout World War II.
These atrocities were criminal activities versus humanity and an outrage that stomped on human conscience.
Yet, numerous Westerners stay uninformed of this dark chapter in history.
