Paper Toys: Given all of the things that are made from paper, it's appropriate then that there is a whole museum devoted to everything that you can make out of paper and the different types of paper from the different regions of Japan. All of the displays had plenty of explanations in English which is quite rare in Japan (from my experience there).
While I was there I met a guy from Sydney who was studying in a Japanese high school as an exchange student. His host family had brought him to the paper museum as weekend outing.
The photo above is of some toys made from paper.
