Those visiting Japan around this time of the year (there seem to be a few forum members who are/will do so) may be interested in buying a copy of the current JTB timetable. The cover feature is the 103 series, which is marking its 50th year of service. It may become a collectible, and certainly will be a nice souvenir of your trip.
