Agree, I'm at the Kagoshima Sheraton and the lady on the Bonvoy queue called over an English speaking helper for my checkin. I suspect that most of their clients would be local, Korean or Chinese so I would like to think that the staff are multilingual, just not English speaking. As a monolingual individual I don't really mind, google translate can help in most situations now.

Maybe the real question is, is it a brand standard to have an English speaking member of staff on duty at all times? I suspect not, it's just good hospitality, at least during the working day.
