Breakwaters Become Brackish Quickly. Brackish=gonorrhea infested

The Recreation and Amusement Association, or more literally Special Comfort Facility Association, was the official euphemism for the prostitution centers arranged for the U.S. armed forces in Occupied Japan after World War II.

The RAA was created on August 28, 1945 by the Japanese Home Ministry to contain the sexual urges of the occupation forces and protect the main Japanese populace from rape. The RAA's own slogan was "For the country, a sexual breakwater to protect Japanese women".
