BACKGROUND HISTORY
Military correspondence of the Japanese Imperial Army shows that the aim of facilitating comfort stations was the prevention of rape crimes committed by Japanese army personnel and thus preventing the rise of hostility among people in occupied areas. Given the well-organized and open nature of prostitution in Japan, it was seen as logical that there should be organized prostitution to serve the Japanese Armed Forces.
The Japanese Army established the comfort stations to prevent venereal diseases and rape by Japanese soldiers, to provide comfort to soldiers and head off espionage. The comfort stations were not actual solutions to the first two problems, however. According to Japanese historian Yoshiaki Yoshimi, they aggravated the problems. Yoshimi has asserted, "The Japanese Imperial Army feared most that the simmering discontentment of the soldiers could explode into a riot and revolt. That is why it provided women."
The first "comfort station" was established in the Japanese concession in Shanghai in 1932. Earlier comfort women were Japanese prostitutes who volunteered for such service. However, as Japan continued military expansion, the military found itself short of Japanese volunteers, and turned to the local population to coerce women into serving in these stations.
Many women responded to calls for work as factory workers or nurses, and did not know that they were being pressed into sexual slavery. In the early stages of the war, Japanese authorities recruited prostitutes through conventional means. In urban areas, conventional advertising through middlemen was used alongside kidnapping. Middlemen advertised in newspapers circulating in Japan and the Japanese colonies of Korea, Taiwan, Manchukuo, and China. These sources soon dried up, especially from Japan. The Ministry of Foreign Affairs resisted further issuance of travel visas for Japanese prostitutes, feeling it tarnished the image of the Japanese Empire. The military turned to acquiring comfort women outside mainland Japan, especially from Korea and occupied China.
Many women were tricked or defrauded into joining the military brothels. The situation became worse as the war progressed. Under the strain of the war effort, the military became unable to provide enough supplies to Japanese units; in response, the units made up the difference by demanding or looting supplies from the locals. Along the front lines, especially in the countryside where middlemen were rare, the military often directly demanded that local leaders procure women for the brothels. When the locals, especially Chinese, were considered hostile, Japanese soldiers carried out the "Three Alls Policy", which included indiscriminately kidnapping and raping local civilians.
