I know there is no shame or guilt about it in Japan. The reason is : they don't have "our" Judeo-Christian morals (eventhough I am an atheist, the society's moral rules influence us since the craddle). So no shame about sex and like other Asian countries, "prostitution" is part of the daily life. In Japan, there are only laws about sex to give an honorable facade internationally and to avoid to disturb public order, from what I have understood (no deep conscience or rigid moral). If it works like this it's might be good, but I am affraid of the spread of diseases like AIDS. Japanese people (especially young girls) seem sometimes so naives and childish they don't even care about using condoms. What's more, it's common knowledge in Japan that only foreigners have AIDS and that Japanese are kind of immune from it. That is very scary when you know that they usually don't take HIV test for they fear to be positive ! Who reallly knows how many people have AIDS now in Japan.
