Japan under US occupation was a depressing case-study of this: > Immediately after the Japanese surrendered in 1945, the Japanese Ministry of the Interior made plans to protect Japanese women in its middle and upper classes from American troops. Fear of an American army out of control led them to quickly establish the first “comfort women” stations for use by US troops. > By the end of 1945, the Japanese Ministry of Home Affairs had organized the Recreation Amusement Association (R.A.A.), a chain of houses of prostitution with 20,000 women who serviced occupation forces throughout Japan. > Five months after the occupation began, one in four American soldiers had contracted VD. The supply of penicillin back in the U.S. was low. When MacArthur responded by making both prostitution and fraternization illegal, the number of reported rapes soared, showing that prostitution and the easy availability of women had suppressed incidents of rape. > John Dower, in his Embracing Defeat: Japan in the Wake of World War II, cites author Yoshimi Kaneko's claim that while the U.S./Japanese-sponsored brothels were open “the number of rapes and assaults on Japanese women were around 40 a day,” but after they were closed, the number rose to 330 a day. https://apjjf.org/-Terese-Svoboda/3148/article.html https://apjjf.org/-Terese-Svoboda/3148/article.html Fair warning about the source: There are descriptions of some really nasty incidents in there.
