Fun bit of trivia: Japanese train stations each have their own custom stamp, and if you have a piece of paper or a notebook they'll stamp it for you at the ticket booth (this is a fairly common thing to do there). If you get an A5 notebook, it's a neat way to document a trip -- one stamp for your departure station, one for your arrival.

Sadly not all of them, much to my ill discovery! They are fun souvenirs and I encourage everyone to collect them if they want a free momento (ideally bring your own stamp pad).
