Perhaps there isn't much hope if all you plan on doing is being an English teacher, though it's not unheard of. Anyway, no one ever said it was easy as 1,2,3. There's plenty of paper work to do and the process for actually becoming a citizen is a long one (one requirement is that you've lived in Japan for at least 5 years). But, the point is, as long as you're not a criminal, it's fucking possible!
Now, you're afraid that no one will like you...boo-fucking-hoo. Seeing as the only information you have on the matter comes directly from *zOMG teh Sauce of All knowledge* interweb you really don't know what it's like. You've probably read all kinds of horror stories about Japanese people hating everyone who comes into their country; not allowing them in bars, clubs, bath houses, etc... OVERLY MISREPRESENTED BULL SHIT.
In my time in Japan(3.5 months), only once was I denied access to a bar. And they simply and politely told my friends and I that it was for Japanese people only. Big deal. We went to 7 other bars that night and had a blast. On all other occassions and encounters I was treated with respect and dignity. In the particular town I was staying in they even let me march in one of their cultural festival/parades.
Anyway, if you do experience some kind of discrimination it will most likely be from either someone older or from the yakuza, can chances are you won't run into the yakuza unless you're looking for trouble anyway. For the most part the young people of Japan are pretty cool with foreigners, especially those who are white. It helps if you're tall and have blonde hair. But hey, I'm short, have brown hair, and a rather muscular physique, and I got along just fine.
But to be honest, no matter where you go you'll never be happy if you're worried about what everyone thinks of you. If you walk into the country constantly worried about whether or not you'll be accepted you'll just be the same as that nerdy kid in high school who was always seeking approval from everyone else. Don't do that. Take the attitude of "fuck you if you don't like me" and you'll do just fine.
The overall point I'm trying to make here is there is a place in Japan for you. But if you're a pussy, pessamistic, or just plain lazy, you'll never find.
And if you're a weeaboo whose only interests are anime and manga, you'll be eaten alive.
