> Not to be depressing, but you could speak fluent Japanese and you will always be "my foreign friend" or "our foreign coworker" or "the white guy with really good Japanese" to, by and large, even your closest friends.
I know what you mean, but I wanted to say that this is true essentially in all parts of the world, with the notable exception of some parts of North America.
I think you refer to the subtle changes of behavior that come with the "you're our foreign coworker" that are specific to a lot of Asian cultures and are highly unpleasant, sometimes even racist.
That, however, is also present in China, Thailand, South Korea, Vietnam, etc.
Interestingly, in my limited experience, the Philippines is an amazingly open and hearty country without this "insider vs outsider" mentality.
