In Japan some restaurants won't allow outsiders to sit and eat there. Japanese only, and Japan is a world of goodie-goodies.
This happened to Crow and I a few times as they'd pretend we weren't there, or they'd sit us somewhere where other people couldn't see us. Another place that served 'foreign food' meanwhile put us at their front-most tables to try to bring in customers, and it worked. 😞
On the train people'd move away from us like we had a force field, some of the older folk would say aggressive things while pointing at us to their friends in their language as if that'd protect them from the intention being obvious, and this was with me following all their social mores other than happening to be a Gaijin.
To make matters worse I then saw other 'Gaijin' and they were being loud and obnoxious in quiet spaces, stomping through holy sites while talking on cellphones if not loudly discussing their wealth in English to the point the neighbors' neighbors could hear it, I saw some drunk white dudes drink and piss in the streets while not giving two shits about the culture (calling it boring even), it's embarrassing. When this is what's being presented to them as foreign cultures I can't even really blame them for responding to me and others this way, especially when you see how old temples are becoming tourist traps and elements of their culture that was once uniquely theirs are selling out for "people like me".
All the same this does not negate a sense of racism that is prevelant in their culture, and much of it is proliferated by having had so long with just their own people to account for. They think they are not racist as a matter of privilege typically over how 'we just don't think about those things', while the US for being forced to tackle it on their own soil, forcing the topic, tends up being portrayed to many countries as the most racist.
I thankfully was already warned from an old colleague to expect this sort of thing. He at a tailor couldn't even buy a coat he wanted because the owner said he was 'too fat' (nevermind that it fit perfectly), and he also reported the force field phenomenon and his powers of invisibility much like I then got to see first-hand.
In short no one cares when Asians are racist.
I actually think it's interesting.
While racism may be everywhere, they come from very different cultural concerns than the US story I've seen far more about.
