I am suprised to see Japanese included here. I do admire Japanese culture, also aware of its history and current power. Only one thing that bothers me, how they see the non-japanese. Correct  me if I am wrong, much to the Jews calling others Gentiles or Goyim, or Kaffir by the fundamentalist muslims, many people I have chanced upon says that as a tourist, you are totally ok with them. As a worker or immigrant to Japan, you are treated differently. Can someone clarify that?
