Japan is know for its toys (or collectibles if you will). I didn't get a lot free time when I was in Japan last month for work, but I did have some at the Osaka-kensi airport. There is a small shopping mall that had a small toy store. I really was expecting more, but of course it was an airport toy store, I get take this to cutesy videos.
Also note: according to the book a Whole-New-Mind (why isn't the Amazon Associates gadget working) Japan's biggest export is now pop culture.
This one is for you Stephanie!
