With the nifty fares I see quite a few people will be doing a MR to Japan soon (including me). I'm thinking about spending one night near the airport (to recover) and one day in Tokyo (I'm doing this twice). I'd love to hear your suggestions about economical ways to enjoy my visits. Is the train or bus the best bet from NRT to Tokyo (weekday arrival)? Can you do tours from hotels near the airport that get you downtown for the public transportation challenged? If you have 48 hours in this city what would be the biggest must do?
