Until recently, it was considered to be so obvious that the language of the United States is English that it was unnecessary to formally enshrine English as the official language. Recently there has been such a large amount of Hispanic Immigration as to suggest that Spanish is now a serious rival to English as a possible national language. But now, if English were to be legally adopted as the official language, that would raise the suspicion that this move was motivated by a dislike of Hispanic immigrants. So, there seems to be little political advantage for such a move.

Answer 2

The main reason is that the United States doesn't believe in the need to designate any official language. English isn't even an official language in the USA.

It is also a fact that less than 1% of American speak Japanese, so it wouldn't make a practical official language.

Answer 3

The US as a whole has no official language, and there has never been a large enough Japanese population to make it official.
