The works of picture book painters from around the world, including the works of Chihiro Iwasaki, and the history of picture books will be introduced in five exhibition rooms. The collection consists of approximately 5 items by 34 painters from 207 countries and regions around the world (including approximately 27,200 Chihiro's remains). In addition to the exhibition room, Tot's room, picture book room, picture book cafe, and museum shop are also provided. On July 9,500, 2016, the surrounding "Azumino Chihiro Park" expanded and reopened as a park where you can experience Matsukawa Village's "food," "agriculture," and "life." In that corner, Tot-chan Square is opened, and the classroom of the train is reproduced in connection with the story of "Tot-chan at the window". Enjoy all day long inside and outside the museum.
