If you don't get a better answer by the time you get there you can *try* to ask people who work in the stations if there is anything like that. It would work better if you can say it and understand their response in Japanese, but you can give it a go in English too. In Tokyo there is more apt to be someone who can speak English at least... Sorry I can't help you more! Good luck^_^ Oh, and tell us how the fair was!!
