According to an account by a survivor, she was beaten when she attempted to resist being raped. The women who were not prostitutes prior to joining the "comfort women corps", especially those taken in by force, were normally "broken in" by being raped. One Korean woman, Kim Hak-sun stated in a 1991 interview about how she was drafted into the "comfort women corps" in 1941: "When I was 17 years old, the Japanese soldiers came along in a truck, beat us and a friend, and then dragged us into the back. I was told if I were drafted, I could earn lots of money in a textile factory...The first day I was raped and the rapes never stopped...I was born a woman but never lived as a woman...I feel sick when I come close to a man. Not just Japanese men, but all men-even my own husband who saved me from the brothel. I shiver whenever I see a Japanese flag...Why should I feel ashamed? I don't have to feel ashamed." Kim stated that she was raped 30–40 times a day, everyday of the year during her time as a "comfort woman". Reflecting their dehumanized status, Army and Navy records where referring to the movement of "comfort women" always used the term "units of war supplies". One Japanese Army doctor, Asō Tetsuo testified that the "comfort women" were seen as "female ammunition" and as "public toilets", as literally just things to be used and abused, with some "comfort women" being forced to donate blood for the treatment of wounded soldiers. At least 80% of the "comfort women" were Korean, who were assigned to the lower ranks while Japanese and European women went to the officers. For example, Dutch women captured in the Dutch East Indies (modern Indonesia) were reserved exclusively for the officers. Korea is a Confucian country where premarital sex was widely disapproved of, and since the Korean teenagers taken into the "comfort women corps" were almost always virgins, it was felt that this was the best way to limit the spread of venereal diseases that would otherwise incapacitate soldiers and sailors.
