Animated characters being unrealistically portrayed I'd say is the least of our worries when it comes to Japanese sexism. I mean, it's still somewhat taboo for Japanese women to express that they enjoy sex at all, and it's not like if characters, both women and men, aren't idealised in Western productions. Not that there's anything wrong with Japanese sexism. Not saying there isn't either. I'm not going to judge a foreign culture.

Other than that. As far as I can remember a certain Shiki looks pretty normal, though she's everything but ugly, and girls in just about any Makoto Shinkai movie are fairly normal looking as well.
