It depends on which part of Japan you are going to. In remote areas people will find you interesting and exotic because you are obviously a foreigner here. In big cities like Tokyo or Osaka foreigners are frequently seen . Relatively like Spring mention, our hospitality is better ( I would say the best !!! ) and less discrimination ( not like in East Europe or America). All you have to do is open your heart and be ready for the new cultural adventure. Enjoy !

First of all, I have to modify your Japanese a little so it's more understandable. 日本人は外国人に親切ですか？　(Are Japanese friendly friendly to foreigners?) 差別は受けませんか？　(No discrimination against foreigners?) I should say Japanese hospitality is better than world average with less discrimiation against colored people than in America. But it doesn't mean you can expect to be treated as frankly as any Japanese.

Hi I'm from Osaka, the secondly biggest city in Japan. I think I have to say that it depends who you're and what you're going to do in Japan. it's true we're commonly polite and good hearted to anyone including people from over seas. actually there're many people are too happy and act like crazy because they're treated speacial. good or not, you'll get all attention if your appearance are different from regular Japanese or if you talk other languages in public. I feel uncomfortable sometimes when people look at us when I'm having company people from overseas and it seems like more interests them when the one looks like Japanese (maybe my frind is Chinese blooded) and the speaking is English more that when the person is a Western. some people take those attentions for advantage and some people don't.
