If you're an old school anime fan, you'll definitely want to check out the Doraemon museum near Tokyo. It's a bit off the beaten path, but getting there is easy. The directions are on the museum site, but we've taken the liberty to paste them below. Of course, there are plenty of Doraemon statues, art, drawings, and even food; but it also contains the work of his creator, Fujiko Fujio. Make sure to get the English guidebook so that you can understand the many pieces throughout the museum.
Note, you MUST buy tickets in advance, there are no ticket sales at the museum, so plan ahead. Tickets are available at any Lawson store (they are EVERYWHERE in Japan, so access will not be a problem).
