For a country often lauded on marks of social sensitivity and public safety, Japan has its share of dark patches. One of the most shocking by Western standards is the porn industry.
Without even considering hentai, Japanese porn has a lot going against it. For a start, Japanese censorship laws dictate that the important bits must be pixelated, which means that you can't quite see why the girl is acting like she's in so much pain.
But despite those harsh restrictions, adult media is very publicly available across the country; nearly every Japanese convenience store has an "Adults Only" section of the magazine rack. And perhaps because of censorship restrictions, the variety of content in the country is never-ending. Unedited depiction of intercourse is illegal, but only in the letter of the law. Imagery of obscene acts involving body fluids, uniforms, costumes, game shows, or even insects, sells in droves. And Japanese people who don't approve of it seem to simply avert their eyes.
The Internet has fostered a similar haven of deviance on a global scale. And yes, it probably out-does Japan every time. But only in Japan does it seem to be granted a physical body. Only here can you walk into a store and see this:
This whole section is titled レイプ, or "rape" to you and me. This type of porn typically makes up about 20% of all porn sales. Try as I might, I've only ever found one shelf of men being raped with strap-ons.
I've heard a lot of people defend Japan's violent sexual media as an outlet for what would otherwise be a rapist or paedophile. And the criminal numbers seem to be in favour of that excuse. UN statistics indicate Japan's rape averages as 1/24th that of the USA and 1/20th the UK's.
Further investigation, however, produces a different explanation: The definition of "what rape is" in Japan is very narrow, and attempted prosecution may lead not only to a rejected case, but to the blame being attributed to the victim (see Sexual Violence and the Law in Japan by Catherine Burns); thanks to a severe gender bias in the legal system. For this reason, it is possible that many more Japanese victims exist who are unwilling to report the crime (though numbers of reports have started to increase since a high-profile serial-gang-rape case made national news.)
The idea that watching rape porn quells the desire for real rape is generally argued to be false. Indeed, how could it be otherwise? Surely a rapists desire isn't just one of observing the mistreatment of a woman, but actively being involved in it. The absurd popularity of this genre only supports the concept of rape being "a fantasy, rather than a crime" for many Japanese men.
Even more disturbing, but very telling of the industry's unrestrained extent, is this section; liable to turn up in many adult shops:
This is lolita porn, not in the "Barely Legal" sense, but featuring real kids. Children.
It flies under the radar because there's no "actual" nudity or abuse. The kids are just provocatively posing or messing around, and the director passes it off as artistic (presumably the intense camel-toe on the girl on the left is just incidental then). But this is for sale. In the porn section.
I don't know what else to say.

I know what to say! Mind your own damn business you moral fag!
It is the primal instinctive nature of human beings to be sexually attracted to certain sexual acts and age groups. This has been the case in every country in the entire world since people moved into those area's.
The only reason why Japan is so popular with its Hentai Manga and Lolicon is because of its art style and they have creativity in other media arts that are different than what others are used to so people from around the world also become interested.
You look at all this porn and view them as perverts and this as dangerous but that is not the case. You should know why, There is a far more depth to this all than you could ever understand and all of it starts by studying more into the "real" culture of the modern people of that country.
This means knowing how those people think, act, and why many of the men and ladies there are so introverted when it comes to sex and intimacy. While some of the Younger Generations are becoming more adventurous and open, There is still a lot going wrong with them.
Which has nothing to do with messages coming from their porn. I myself do not agree with everything they do but calling all of it sick
and perverted with knowing you obviously do not understand the full picture is just wrong.
