Asian countries may be more xenophobic due to past event in history, anyway that's the way I see it, and you know Europe weren't as much open as Japan in the past either. Also, I experienced racism in my childhood and even in late high school, having been thrown rocks at, spit in the face, mocked, sprayed chemical products in the eyes... by other kids, so I don't think racism is worst in Japan than anywhere else, god you people should grow up.
