I don't understand what you were trying to accomplish in this thread. You ask, "Are Japanese people racist?!" yet you already seem to "know" the answer.
Based on what you see on TV doesn't warrant whether a country is racist or not. Japan is very homogeneous so naturally most of the people who appear on TV networks will be Japanese. America is very diverse so, naturally, you see many diverse people on TV in the US. You should probably develop your point a lot better, especially past what you observe on TV.
