Uhmm, this is all a little insulting... Not to mention embarrassing, because the OP is clearly ignorant to the subject.
Sure, a lot of people speak some English but I find it more like a novelty rather than fluency.
Does America even have an "official" second language? If we aren't willing to adopt Spanish, why the hell would the Japanese (or anyone) consider this a possibility?
Shouldn't there only be one "official" language?
Branding English a secondary language is a little eccentric, and unrealistic.
