I could do my own research

But since most of the people posting here are far smarter'n me -- and have access to dissertation databases and Nexis/Lexis and what-not -- I'll ask:

Any good studies on stereotypes regarding black people in postwar Japan and Germany? Specifically, how those attitudes may have been related to or influenced by exposure to American attitudes?

Germany's just there for contrast; mostly it's some of the stuff in Japanese pop culture -- anime, manga and videogames -- that makes me a wee bit uncomfortable. Seeing [white] Americans comment on such makes me a lot more uncomfortable, as there's that whole self-congratulatory tone when pointing out someone else's racism.

Anything fresh on the Ainu or treatment of n^th generation Korean immigrants couldn't hurt, might help.

For "fresh" read "not telling me they're discriminated against, I got that much already, thanks."
