But it's a reality that English is the primary (if not sole) focus, for historical reasons and as the global lingua franca. English is taught (poorly, from what I hear) in schools, played on train announcements, is the only Western language available on ticket machines, and is the assumed language of non-Asian visitors to the country. I was even on a couple of domestic flights a few days ago and the captain / FAs made announcements in English. It is not "arbitrary" at all.
