Man please.That's your assumption. Japan is a different culture. They have considerably different opinions on the nature of nudity, which is both more reserved and lessreserved than most Western countries. I lived there for six months and you can walk into a bookstore and see boobs on the cover of a book right next the children's section. They bathe - naked! - with their children. Communal bathing is a universal Japanese bonding experience. Hell, one time I was peeing in a men's room when a cleaning lady came in and started scrubbing toilets as if I wasn't there. Another bit of culture clash for me was the willingness for men to pee anywhere on anything, even if a mob of people are standing right behind them.
And this is where you are projecting. You are answering the question from your perspective. The designers themselves obviously don't see this dichotomy. They didn't go, geez, it doesn't make sense but I really want to have some big boobs here. They are aware of the themes of their game and the designs employed in it, and if they didn't see the same problems you do, maybe it is because they aren't looking at it through your eyes. Instead of constantly trying to put the designers in your shoes, why don't you try putting yourself in theirs?
I'm not sure you know what you are talking about with the "typical Japanese demure personality" thing. If you ever find yourself in Japan, see if you can't find a phonebooth and look in it. Dollars to donuts, it is completely wallpapered with packs of tissues with naked ladies on it.
Don't talk about Japan like they're some sort of alien culture so far removed from the rest of the world that they don't hide their shame and freely display acts of lust and debauchery openly. They're not. The mindset you're pushing right now is some anime bullshit.
When I was in japan, the only place I saw napkins with naked ladies was in Roupongi, an area that's only about as bad as South Boston but is lauded as the most dangerous place in Tokyo. There certainly wasn't pornography lining the streets, there certainly weren't scores of women asking for sex, the worst I saw was a few drunk businessmen. If anything, Las Vegas on some idle tuesday is worse than the very very very worst that Japan has to offer.
Your idea of what Japan is sounds like it's only gleaned from Yakuza games.
"But exposed titties is part of their culture!" Get the fuck out of here with that bullshit. And I say it that bluntly because it is BULLSHIT. It's not true. It's enthusiast media bleeding into the mainstream as technology changes. It is ANYTHING but the norm. It is DEFINITELY seen as embarrassing there as it is here.
This is american.
in that there are a lot of people who don't know how to even start to confront the unrealistic idea of beauty that our society has set forth
