The museum has a collection of about 400 kaleidoscopes from japan and abroad, and changes the exhibits three to four times a year based on a different theme, with 50 on display at any given time. in the exhibition space, a projection kaleidoscope operates for about three minutes every hour, creating a fantastical space. in addition, they hold classes on how to make your own kaleidoscope from time to time. there are classes that anyone can participate in, such as "classes you can do at any time," and "special classes" where you can receive lectures from artists, allowing you to create your own one-of-a-kind original kaleidoscope.
