I honestly don't think this is that bad. I've been to Japan, and it's true that you can walk into almost ANY convenience store and find disturbing porn. Both in manga, and photograph form. I can enjoy porn if it depicts two people being intimate and having normal sex, but the depictions of women in both anime and video doing so much disgusting shit is really offensive. I'm sure Japan would be a better society if they didn't have so much material with women being dominated and horribly sexualized in their anime and manga.
For Example, (This is quite a sexually explicit example, be warned)
When I was in Japan, I was horny one night and borrowed a porn video from a Japanese friend titled - "Dream Shower." I figured - "Ok, this is probably about some people in the shower having sex, right?" But I was horribly wrong... In the video, there were a bunch of different scenes, all scenes featured one naked Japanese woman and about 10 or 12 naked Japanese guys. The guys would chase the woman all over the house, until they finally caught her, and then one would do her on the floor while the other 10+ guys were jerking off all over her body and she would be totally cum-soaked. get it? "Dream Shower." It didn't end there either, then there were two girls they made eat different things, vegetables and stuff, out of each others' assholes for a half hour (I forwarded the video of course, didn't wanna watch that shit for a half hour)!
I don't know how much they pay Japanese women to do porn, but it must be a lot because that video had some of the worst things I've ever in my life. It puts American S&M porn to shame. I've also seen things equally as bad, or stupider, in Manga and Anime. All of the weird tentacle sex scenes are just stupid as hell. Japanese guys should respect their woman more, it's no wonder the women don't wanna marry those guys and their population is declining terribly.
It would be better to ban all porn like that in Japan.
