Japan specifically is extremely xenophobic, they actively discourage people from immigrating, they do not want foreigners there except as tourists. If you are not born in Japan, you can never become Japanese as far as the locals and the government are concerned.

It's kind of reductionist to take that environment and that culture and just default to "giving the white guy the expensive menu is racism." You'd have to do that to probably 1500 people before you hit the person who has actually immigrated as opposed to a tourist.
