This is a facility where parents and children can interact with each other, combining a picture book library and an art museum.

The oval-shaped interior of the museum can be circled. Visitors are asked to take off their shoes to enter the museum, so they can sit or lie down on the ground and relax as if they were at home.
In the "Ehon no Heya," a variety of picture books fill the low-backed bookshelves.
Picture books for babies, folktales, crafts, animals, plants, vehicles, picture story shows, large picture books, cloth picture books, etc. are arranged in each corner. Gokko-House," a furniture house for playing house, and "Wooden Puzzles" are also located here.
