What are the most and least racist countries in the world?

Japan is, in my personal experience, one of the countries where I feel myself more comfortable as a foreigner. I have never during my numerous visits felt discriminated or segregated in any way, and when I talk to other Westerners that live there or visit often, most tell me same. However, please note that I stress "Westerners" because some of my acquaintances of Asian origin (Taiwanese and Chinese mostly) do tell me that they sometimes feel discriminated against in Japan, but not all the time.
In fact, many of them had their worst discrimination experiences in Western Europe, not Japan. A Chinese friend of mine has vowed never to visit France again after she was refused service at a locale. Still, she likes to go shopping to Tokyo and has no problems.

Part of that is likely the deeply ingrained politeness and aversion to conflict. I doubt you're going to find fewer people in Japan who hate Chinese tourists than in France, the Japanese are just less likely to vocalize this than the French, who are pretty much culturally the exact opposite when it comes to voicing opinions.

I visited Japan for the first time last month and was very impressed by a number of things. I'm even considering going there for work -- but I'm not under any illusions that I'd ever be seen as anything other than gaikokujin by the average Japanese.
