I am studying in Japan to later become an EFL teacher here, and possibly later an ESL teacher if I move back to the US.
Then you've got it all a**-backwards.
You're going to teach English as a FIRST language in Japan, and as a SECOND language in the US?

I think a native English speaker can teach a different language to other English-speakers, and that's fine. If they're good, they'll still lag behind in pronunciation, but they might surpass a native speaker in other areas, having learned the language formally.
At my university, I'm learning Japanese, and several of my teachers have been native English speakers -- they taught the "translation" component, which was ideal for them, because it required the translating of Japanese texts into accurate and natural English. It is always easier to translate a foreign language into your own language than it is to do the reverse.
But I wouldn't want, say, a Chinese guy who learned both English and Japanese as second languages to teach me Japanese.
