A lot of people seem to think Japan is a lot more reactionary than it really is. Last year, the education ministry announced a policy for "promoting proper understanding of teachers on … sexual orientation/gender identity as well as making sure to inform on the school's necessary measures regarding this matter.". And they're currently ruled by the LDP, their conservative party, so this isn't even considered left wing. While they make creepy cartoons, possession of actual child abuse images is illegal, unlike in certain other countries, like Russia. It's weird no one accuses Russians of all being depraved paedophiles, but I guess that's too much for people who define their entire world views around cartoons and video games.
The main cause of this, I think, is that very reactionary countries would probably censor anything too provocative, so even those games and media they do produce (Mount and Blade in Turkey and War Thunder in Russia, for example) aren't considered insensitive to PC types. Japan is in the position of being slightly more socially conservative than PC Americans, but not so much more that cartoon titty video games would be banned. I do find the idea of Spoony in Sudan amusing, though. The age of consent is 10, but sodomy is a capital offence.
