Miyoshi is said to be the setting for Ino Mononoke Roku, a book about yokai from the Edo and Meiji periods, and the museum primarily exhibits materials related to these yokai.

Additionally, there are digital contents created by teamLab, where children can color yokai pictures that are then projected onto the wall and the yokai comes to life.
This is an entertaining activity for elementary school children.

There are also tourist information centers and dining options available on the same site.
