I also live in a country where English is part of the curriculum, and as someone attending his final year at college, somewhere where all my classmates must have finished their secondary schooling to be there, I can assure you that plenty of them do not know English.
It's hard to say what is Fujino dealing with in terms of English with his own knowledge and what he is using a machine translation for, but taking into consideration the fact that "Now Game" has been used instead of "New game" in almost of all of his games across the years, among many other strange mistakes, I wouldn’t bet Fujino's level is beyond that of an elementary school student in an non-english speaking country.
