And some ones concerned that Japanese
Enjo-kōsai (援助交际) already had a great influence in our culture.
Enjo-kōsai 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.
Furthermore, in a 1998 survey by the Asian Women's Fund, researchers found that more than 20 percent of all high school girls engage in enjo-kōsai
lol that's pretty great.
