The Science Museum, where Chiaki Mukai, an astronaut from the city of Tairin, serves as honorary director. It is enriched with valuable materials related to Mukai, which cannot be seen elsewhere. There are many hands-on exhibits that use the principles of science, such as "Moonwalker" and "Power Generation Train", where you can experience the gravity of the moon, and you can enjoy and learn about familiar nature, science, and the universe. At the digital planetarium, which is viewed on a large dome with a diameter of 23m, one of the largest in Gunma Prefecture, you can enjoy a unique sense of sound and powerful images.
