> Even today, an admittedly unsubstantiated observation is that the US recognizes that there's a problem with racism within its borders. Japan doesn't seem to. Here's a quick test: imagine if your daughter wanted to marry a Black man. Who do you think would have more of a problem with that, an American or Japanese parent?

I agree with we don't realize that we have racist consciousness potentiality, but I think Japanese don't have eugenics or idea like caucasians had, which specific race is greater or evolved than other.
Your example, what we think if daughter wants to marry with black male, is little hard to imagine, but we might think it is problematic because he is foreigner, before he is black. his nationality or race may not be a probrem while he lives in Japan and speak Japanese.
Now back to my post, I call in question the Japanese Empire is racist or not. In the Japanese Empire, citizens could marry with other race living in its border legaly, but in your country, marry with not white (negro or mulatto) is banned in several states.

sorry for divided post.
