I had a conversation with a Japanese American artist a couple of years ago on the general topic of the post-WWII infantilization of Japanese culture. I believe we reached a sort of mild agreement that Japan's collective unconscious is still trying to process the shock of being on the receiving end of a nuclear attack.
Please, can you give some details about this "infantilization"? I can't be the only one who can't think of anything other than Hello Kitty.
One thing that jumped out at me was what appeared to be a widespread fetish where the ideal woman looked like a cupie doll type school girl, almost like a living anime character.
There were also a lot of free "manga" around (anime magazines) and not only where these schoolgirl characters everywhere, raping them was a common theme.
I loved my short stay in Japan, and I had a lot of positive experiences there, but that aspect of the culture was downright creepy.
