watch?v=3KSjaUM0dbE Enjo-kōsai (援助交際) (shortened form enkō (援交) means "compensated dating" and is a practice which originated in Japan where older men give money and/or luxury gifts to attractive women for their companionship and, possibly, for sexual favors. The female participants range from primarily school-aged girls to housewives. A common misconception is that enjo-kōsai always involves some form of sexual activity. The term enjo-kōsai first appeared in the Asahi Shimbun on September 20, 1994.[citation needed] In the opposite case of women paying men, it is called gyaku-enjo-kōsai (逆援助交際), or "reverse compensated dating". above copied and pasted from wiki For more details from wiki http://en.wikipedia.org/wiki/Enjo_k%C5%8Dsai
