Graphic violence usually involves actually seeing the person receiving the violence. Showing an image of a girl lying on the floor in a pool of blood is not graphic. You don't see how she is killed. You don't see the stab wounds. Some other examples you have added are slightly different, and definitely fit the graphic label more appropriately. But then again, Zero Time Dilemma is indeed more violent compared to the 1st two games. But again, its largely able to see a release because most of the violence is not being shown in its entirety. Violence being received is happening off-screen (this is what I meant, sorry) with the results shown later. Sure, some of these are quite intense but then we go back to the argument of how violence is more acceptable due to various socio-historical and entertainment factors.
Showing a character, who looks like a child, being groped is not remotely the same thing. A key difference here is that in Zero Escape, you are not the one controlling the violence. In a game like Omega Labyrinth, the groping action is actually being controlled by the player.
Which comes to the age of consent issue. No, the laws governing age of consent in JPN are not complicated. No where in JPN is the age of consent 13, except for 2 very lowly populated and isolated islands. Every prefecture in JPN has the age of consent at 16 for women and 18 for men. In line with the USA and EU.
The game passes in JPN because opposition to it is still low. Which shouldn't surprise anyone considering JPN only banned child pornography 4 years ago. laws are black and white in JPN so its easy to get around the problem. That doesn't make it ok.
Dont let others fool you. you are correct. The age being 13 is just a misunderstanding of how laws in JPN actually work.
I've read through the posts and it looks to me that no one is entirely wrong. The situation is somewhat complicated; not necessarily in the sense of being difficult to understand (It's not.)
Age of consent being 13 in two essentially unpopulated Japanese islands still makes it mentally easier and more common to sympathize with glorified pedophiles. What's legalized in a small part of Japan can't be demonized by the larger part, so I can see this misleading "minimum age of consent" playing some role in the general tolerance of relationships with young girls. Their cultural roots and the "romantic relationship card" further "forgive" such development; if some dipshit is convicted in Tokyo for having an affair with a 13 year old, he may get out of it using the romantic relationship excuse or bringing up the otherwise useless country-level age of consent to make himself look less terrible than he probably is "I've made a small mistake, now get me out of here!"
There's a fairly obvious correlation between the growing lolicon sub-culture and this seeming indecisiveness/flexibility which is most likely rooted from the culture itself. Countless nations were pedophile-ish by today's standards but Japan is yet to completely grow out of it.
With that being said, I'm more surprised by Israel's policy on this. Strange to see a few developed countries behind most developing countries in this respect.
