2027 Chichibu Muse Park Starry Sky: A Full-Day Course

At Chichibu Muse Park, which spans Chichibu City and Ogano Town in Saitama Prefecture, the “Chichibu Space Fan Club” holds star-gazing sessions during the summer holiday season (supported by the Chichibu Muse Park management office). In 2026 these were held on Saturdays July 25, August 1, 8, 15, 22, 29, and on Wednesday August 12, at the “Multipurpose House” or the “Chichibu Taiheiyo Cement Concert Hall,” where visitors could observe summer constellations, the moon, Venus, and the Perseid meteor shower. Since the official website does not clearly state the hours, fees, or whether reservations are required, please check the official site (muse-park.com) before visiting. During the day you can stop by Michi-no-Eki Ryusei-kaikan (9:00-16:30, closed Tuesdays, adult admission 350 yen), and in the evening at Seibu-Chichibu Ekimae Onsen Matsuri no Yu (Sat/Sun/holidays 10:00-24:00, adult admission 1,380 yen).
