My parents may be sort of distressed to hear this, but when I first got here, a friend of mine (Nien) said something to the effect of, "Don't worry. Even if you aren't Chinese, you will be." I didn't really believe him at the time but over time I've started to feel like eventually it might come true.
At the end of the day, I don't really feel much connection to Japanese culture. I mean, I like Haruki Murakami, as much as the next person. And there's some stuff I really like, manju, chirashi rice, miso soup, and as the Boondocks once put it, "their really really cool cartoons." However at the same time, possibly due to the fact that I once had many Korean American friends, I also don't feel much connection towards Japanese people. Certainly other Japanese people don't welcome you as one of their own. Japanese Americans are another story. Also I don't speak the language, which also sort of seperates me from this. I haven't really found it true here. Honestly, it probably helps that I look Asian.
And I find that there are some things that I understand because I came from a (vaguely) Asian family. And so I find that many people characterize me as "half a foreigner" or tell me things like, "You work hard because you are Asian." or 你很東方. Honestly when I was in America, I was always considered a foreigner anyway, so it was hard for me to think of it as really my country. I don't really belong here either, but sometimes it feels like I could.
