I thought of it and then remembered that it's an alternate universe and maybe it's quite possible they just all speak the same language.
Well, they DO speak Japanese and English, I'd assume, given all the stuff in the background all the time. It's possible that the rest of the world speaks English while Japan is the odd one out, but I doubt it. For a show with this much detail that would just seem...lazy.
On your second point though, it makes a lot of sense that way. I think all our main characters are probably bilingual, it's just never brought up.
