Will be leaving for a trip to Japan this evening and would like to find out how I can pay for my stuff (e.g. hotel, restaurants, shops, taxi) in Japan...need cold hard cash or credit card? In particular, I'll be buying some cameras (prob. in the Akihabara or some other shops listed in kakaku.com), do they accept cash only or is credit card ok?
I'm thinking of changing more cash, but worried about losing!
