I'm actually in Tokyo right now, and there really isn't much warning that is needed to be given. Most STORES in Tokyo take credit cards, but for resturants (particularly the traditional ones) you will want cash. Hmm what else... everyone is very nice here so you won't have a problem if you need help with something. Hotels here get booked very very quickly, so I suggest you get a reservation as soon as possible as to avoid spending the night on the street you will do fine
