I am contemplating a visit to Japan and would like to visit two different places: Tokyo and Okinawa. Are these places ok for someone who speaks English and no Japanese? Are seats in the plane labeled with English numbers and letters? Can you find your way out of the subway? Do restaurants have menus in English? Can you take a boat from Naha/Okinawa to a nearby island without speaking Japanese and knowing their alphabet? If Okinawa is only so-so with English coverage as I suspect it is, could you suggest another place with nice beaches for relaxing?
