If you think you've known enough about musical instruments just come here. In a such small building there is located dozens of auto playing musical instruments from sizes of matchbox to the two floor structure. The most impressive thing for me was the way those instruments are working. This is just completely blow my mind even tho I'm working with AI and stuff... Geniuses! Staff is patient and helpful, they will show and tell you (on the good enough English) how does all works. As a plus there's a quite small exhibition of "Europeans musical instruments in Japan", but it's fully on Japanese so I just didn't understood anything. What's surprised more is a collection of works of the most famous clothes designers and models (don't want to spoil anything so will attach only approves that there is such a thing). In the museum there is shop where you can buy lot's of matchboxes from 1,000+ ¥ with almost any music genre you want to hear, good support for a nice place. Also there's cafe where you can buy some sweets, and I do recommend gelato and tea, yes it's rare to find this kind of tea in Japan. Overall it is good place to visit. Won't scream "10/10" in case not everyone would be satisfied by this kind of museum, but anyways give it a try it worth it.
