I'm headed to Tokyo next month, and since I know there are quite a few people here who are in or have been in Japan I thought I'd ask for any tips I can get. Some specifics: I've heard that Credit Cards / ATMs are not too widely used in japan. Am I going to need a ton of cash? Also, I'd love to take a day trip skiing while I'm there. Firstly, would this even be possible from Tokyo, and if it is, does anybody have any recommendations for a resort that's readily accessible by train? We'd like to see some sumo, but as far as I can tell there aren't going to be any matches (games? meets? I don't know what to call them) in Ryogoko while we're there (Mar 1-8). When does baseball season run in Japan? And of course, any and all tips, anecdotes, warnings etc. will be greatly appreciated. Thanks!
