My wife and I (non Japanese speaking)just returned from Tokyo last week on a short holiday. It is true English is not widely spoken but we got by. Most locals will not converse with you even if they know the English language.Tokyo is not really tourist friendly, IMO, as in, you really need to know your barring to get around. Transportation system is excellent. Restaurants can be tricky. As stated above, some have vending ordering at the door and are in Japanese. Also, smaller restaurants are cash only.
