I'm guessing you're not a minority in the US, if you think that Japan's racism is a tier higher than the US.

I get that Asia can be pretty racist, but until they start imprisoning minorities disproportionately, or implementing policies like stop-and-frisk, or allowing police to shoot unarmed minorities, then let's just step back for a minute. Not being allowed into a club or getting dirty looks from your local girlfriend's family sucks, but let's not pretend they're on the same level.
