The International Military Tribunal for the Far East stated that 80,000 women were raped, including infants and the elderly.[19] A large number of them were systematized in a process where soldiers would search door-to-door for young girls, with many women taken captive and gang raped.[20] The women were often then killed immediately after the rape, often through mutilation, including breasts being cut off;[21] or stabbing by bamboo (usually very long sticks)[22], bayonet, butcher's knife[citation needed] and other objects into the vagina.

Monks who had declared a life of celibacy were, according to some claims, forced to rape women
