"Common"? I have to wonder about that. Porn itself is already pretty niche, much less bizarre "kinks" like these. Sounds to me like someone read about it and it got blown up into some sort of racist stereotype about Japanese people in general.

The Japanese make a lot of porn (live action, animated, drawn... on that last point, every popular anime gets LOTS of fanmade porn mangas (called doujins) that are sold in stores (that specialize in such things and are bought by otaku fans). That wouldn't be legal in the US, but it's allowed in Japan. Not all doujins are porn, of course, but lots are.) Of course otakus are a niche group, though. But even so, we are talking about what it is, so regardless of how "common" it is society-wide, that's beside the point I think.

Also, how often do you describe sex as "attacking"? That's kinda creepy.

Yes it absolutely is. I'm pretty sure that a lot of Japanese porn (in any form) has rape in it, and tentacle stuff is almos4t always that way I think -- I'm sure there is some consensual tentacle sex stuff out there, but the stereotype is the other way around.

And yes, I do think that that's a sign of how far Japan has to go in terms of gender relations -- Japan and South Korea have the biggest pay gaps between men and women of any first-world nations outside of the Middle East, and that their porn is so disturbingly full of rape is yet another sign of their lagging behind on gender, I think. I have no idea why people would want to see that kind of thing... it's pretty messed up. You see hints of this in regular anime too, not only stuff with actual sex in it. I mean, on this point, tentacle scenes are very common in "ecchi" animes; I think that the only real difference between that and the hentai (porn) versions is how far things go. But of course, that kind of anime is only shown in the middle of the night and is just for that definitely niche otaku audience, so it's not something generally popular... I have no idea of what Japanese society as a whole thinks of such things. But manga is popular, and that's how it is there too -- and not just in stuff for guys, either; in gay (yaoi) mangas aimed at female audiences, rape is also apparently extremely, extremely common. Come on Japan, join the modern world sometime... that is not okay.
