I can't help but notice that the more popular clothing style nowadays seem borrowed from America and sometimes Europe. Listing themselves as white? That's kinda funny. I'll look that up later.
My exgf was chinese. Plenty of chinese, Korean, Thai, etc. in Japan. She never dated black guys before me, just other chinese and white guys. She didn't like Japanese men though. I think it was just a matter of dating who made who happy.
You want the truth? Most think you are African. Which wouldn't be a problem except that a minority of Africans are literally pimps and sleezy club owners. Or, if you meet a girl in a club, they think you are a playboy. There are a lot black people in Japan already. Some Japanese girls are easy...
