Here is an interesting take on the Japanese culture and men and women relationships. Maybe not bad to be a American on Japan after all.
"Additionally, when talking to my female friends (including my Fillipina roomate) who had Japanese husbands or boyfriends, the biggest complaint seemed to be the lack of sex or affection in the relationship. One of the women expressed the opinion that most Japanese men were impotent. A lot of news articles in the English press in Tokyo point to the general uptight attitude of the average Japanese toward matters of sex in general.
A lot of foreign men see Japan as a place where men's "needs" are dealt with in a "non-moralizing" fashion. Well, that's pretty true if you are dealing with any aspect of the prostitution industry, anywhere in the world. I can name a number of places in the US, mainly in Nevada, San Francisco, and West Hollywood, and any red light area of any major city, where a man on the make won't come into contact with a single moral admonishment when in pursuit of a good time.
One cultural difference that men find attractive about Japan is that women in Japan (and Asia in general) are brought up to cater to men, at least on the surface. Japanese women find North American and European men attractive because these men were raised in a culture where they were taught that ladies should be treated with kid gloves. In addition, Japanese women, unlike their Korean counterparts, don't really care that much about looks. It's no accident that Japanese women and Western men find each other charming.
The Confucian system puts men over women. Consequently, sex is thought of as something that males shouldn't need to control - it's sort of treated in the same manner as passing gas - it's something that "can't be helped" (shoganai). Sex (for men, at least) is looked upon as a bodily function - it certainly is not attached to romance as it is in the West. So, if unromantic, casual, no strings, mechanical sex is your thing, Japan (and Asia) is the place for you.
This domination by males explains in part the wealth of graphic sex in the Japanese media. A number of American and other foreign men that I worked with complained that the average Japanese male's ideas about sex were "so 6th grade". Most of the sexually explicit material I have seen in the media there certainly does point to a low level of maturity on the part of the creators and their audience.
The idea of "needs" is not extended to women. Nowhere on the planet is prostitution a profession that is considered honorable, nor is a woman who "sleeps around". Japanese women still go to plastic surgeons to have their hymen repaired before marriage, so they can become "virgins" once again.
Clemens and his bretheren see nothing wrong with double standards, as long as it suits their needs, or as Dr. Phil would say "If it ain't broke, don't fix it". The tone of this book is a couple of frat boys out on the town, living it up, giving tips on where to find girls that put out. And that's all well and good, because this is a guide to prostitution in Tokyo, nothing more."
