My wife and I popped in more or less on a whim to eat up a half an hour before our journey to the airport.
While we didn't have time to fully explore, we greatly enjoyed what we did. The origami on display on the ground floor was very interesting (the little vignettes of the 47 prefectures) and impressive (the tiny, intricate Fuji/sakura displays).
There were also some interesting items available in the shop - it features more than just regular origami paper.
We also had an engaging conversation with one of the staff members. They clearly love origami and enjoy talking about it.
They run classes on site too, though obviously we didn't have any time to take part.
