I voted NO.

English in Japan has no historical nor political reasons to become a secondary official language.

I should address some important issue about English:

Though the sudden dominance of English in the world's academic domain is why universities in non-English speaking countries losing significant ground. For several decades and still today, universities in first world English speaking countries have total dominance in the academia, quasi-permanently. It has discouraged universities in Japan, Russia, etc. to even become important in the long run.

There is a huge presense of heavily-biased oligarchy in globally-connected academia because of English. Hence, the so-called English-superior movement has regressed the whole essense of academia worldwide.
