I've lived in Japan for many years and speak Japanese alright (disclaimer, that was a long time ago though, in the 90s) and now live in Germany. I travel a lot.
I think what you're saying is directionally correct, but really more of a difference in degree.
For example, I've often seen Asian-Germans being addressed in broken English by older Germans, even though German is their strongest language. Or being complimented on their fluent German. That's got to feel pretty "othering".
And don't tell me the country that just elected mister Trump is as open to the world as is often claimed.
This may all feel completely different if you're around the right group of people, and I imagine that's similar in Japan today, though I haven't been back in a long time.
