The choices for a Japanese man wanting an affair outside of marriage are escort services, brothels and sexual massage parlours.
Unfairly enough, there are few sexual services readily available for women seeking paid sexual gratification - or even easy ways to have extra-marital affairs, the Japan Times reported.
If a man is well-connected and wealthy, he can even register himself with a members-only club and be matched up with a perfect mistress.
There were sexual massage services for ladies, and not so long ago there was a brief boom in take-out hosts. However, there is nothing close to the male-centered sex industry accounting for 2 percent of Japan's GDP.
Japanese wives do have affairs but are just more discreet.
