As documented by Japanese site Game Watch (and a handful of other folks lucky enough to visit the museum before launch), the 'Bonus Stage' store is home to shed-loads of seriously tasty-looking merch including cushions, pins, t-shirts and more for every Nintendo console. Every. Single. One.
Of course, this will come as no surprise to anyone who has been tracking Japanese merch for a while, but seriously, check this stuff out!
You can find a selection of these goodies in the following posts, but a full gallery is also available on the Game Watch site.

Pretty sweet, huh? We'd imagine that a lot of these pieces will be exclusive to the Kyoto museum store, but you won't catch us complaining if Nintendo does decide to send 'em worldwide.
