Were you born in Japan and raised there?  Or visit there often?  Reason why I ask is I visit Taiwan and China often, and racism seems almost non-existent.  Sorry to say this, but about the only negative feelings they have that would be considered racist would be the Japanese because of what Japan did during WWII.  Anyway, the culture in Taiwan and China is very homogeneous, so I'm suspect they don't feel "threatened" by other races, as is the case here in the U.S.

I have to admit it's refreshing to go somewhere where there isn't so much infighting based on race.
