Brothel In Japan

Military brothels
Until recently, in several armies around the world, a mobile brothel service was attached to the army as an auxiliary unit, especially attached to combat units on long-term deployments abroad.
Because it is a touchy subject, military brothels were often designated with creative euphemisms. Notable examples of such jargon are la boîte à bonbons (English: "the candy box"), replacing the term "bordel militaire de campagne". Women forced into prostitution by the Japanese occupation armies throughout East Asia were known as "comfort battalions". The prostitutes were individually referred to as "military comfort women" or jūgun-ianfu.
It is estimated that a minimum of 34,140 women from occupied states, particularly in Poland, were forced to work as involuntary prostitutes for the Nazis during WW2.
