Many Japanese don't realize they're the race that gets discriminated in some parts of the world. They assume racism is someone else's problem. Japan's history of discrimination includes targeting within the Asian race, and nationality, which goes to show hate has no boundaries.

Japan's discrimination extends not only to children of Japanese who married non-Japanese and to non-Japanese overall, but also to Japanese who were educated abroad, who may have a sickness, who may have dyed hair and rings in their noses, who may be homeless, whatever.

Such divisions and mentalities of exclusion criss-cross over Japan's social fabric so much you would think it would be too convoluted to become systemic, that the same individual would be both the oppressor and the victim, cancelling each directed hate out. Think again.

Interestingly enough when you point this out to mainstream Japanese a typical reaction is: You have a victim complex. To point out victimization just brings more victimization. That’s why people “pass” when possible (i.e., they are the same in appearance) and keep origins hidden.
