Yes. It's very different to what you get, for example, in Australia. Or most parts of Europe. Yes, you'll probably be a gaijin forever, even if you get naturalized (and renounce to your other nationality). But there's a huge difference between what the japanese are, and have always been, and xenophobia. Of course you get a different treatment unless you show them what you know and your respect, but it boils down to the kind of society it is and the fact that you're, at first sight, different from them. But different, not worse.
