"Comfort women" are a widely publicised example of sexual slavery. The term is a euphemism for the 200,000 women who served in the Japanese army's camps during World War II. Historians and researchers have stated that the majority were from Korea, China, and other occupied territories part of the Greater East Asia Co-Prosperity Sphere, and were recruited by kidnapping or deception to serve as sex slaves.[35][36][37][38] Many women were raped to the point of death or killed by torture, such as having their breasts sliced off or having their abdomens slit open.[39] Each slave was reportedly raped "an average of 10 rapes per day (considered by some to be a low estimate), for a five day work week; this figure can be extrapolated to estimate that each 'comfort girl' was raped around 50 times per week or 2,500 times per year. For three years of service ? the average ? a comfort girl would have been raped 7,500 times." (Parker 1995 United Nations Commissions on Human Rights)
