Prostitution in Japan was well-organized, and the Japanese government and military developed a similar program to provide sexual services to Japanese Armed Forces. Military correspondence within the Imperial Japanese Army shows that there were a number of the aims for facilitating comfort stations: to reduce or prevent rape crimes by Japanese army personnel in an effort to prevent a worsening of anti-Japanese sentiment, to reduce venereal diseases among Japanese troops, and to prevent leakage of military secrets by civilians who were in contact with Japanese officers. Carmen Argibay, a former member of the Argentine Supreme Court of Justice, states that the Japanese government aimed to prevent atrocities like the Rape of Nanking by confining rape and sexual abuse to military-controlled facilities, or stop incidents from leaking to the international press should they occur. She also states that the government wanted to minimize medical expenses on treating venereal diseases that the soldiers acquired from frequent and widespread rape, which hindered Japan's military capacity. Furthermore, Yuki Tanaka suggests that local brothels outside of the military's reach had issues of security since there were possibilities of spies disguised as workers of such private facilities. Japanese historian Yoshiaki Yoshimi further states that the Japanese military used comfort women to satisfy disgruntled soldiers during World War II and prevent military revolt. He also asserts that, despite the goal of reducing rape and venereal disease, the comfort stations did the opposite—aggravating rape and increasing the spread of venereal disease.
