I'm a big guy, sometimes people make space for me on the train or whatever. It isn't racism. I'm a scary and weird looking guy too by local standards, it isn't racism when people gawk a little sometimes. People talk to me like a kid after I completely botch some basic phrase
The only racist thing that ever happened to me in years living there was this: I went to a bar with my white friend, and they said "No American" and made an x sign at us. I asked in Japanese "sorry, what was that you said?" and suddenly they welcomed us in.. I guess they just didn't want rowdy dudes who can't speak the language. Definitely not acceptable behavior from them, but not too bad IMO. I get way worse treatment in the USA for being Hispanic than I ever do for being a foreigner in Japan
The expat community in Tokyo is kinda obnoxious. There are a lot of lazy, burned out guys who complain about everything
How is that unique? Sounds like the expat community in any other Asian city.
