2026 Full-Day Course: Stargazing at Saitama Prefectural Naguri Genki Plaza

Saitama Prefectural Naguri Genki Plaza (埼玉県立名栗げんきプラザ) is a prefectural social education facility in the mountains of Oku-Musashi, where visitors observe the moon and planets through actual telescopes at night as part of experience programs such as the parent-child overnight stay program (past example: Moon and Saturn Viewing and Udon Making). This is not a regular one-off stargazing session but an overnight-stay program, so participation requires an accommodation reservation. Please check the program content, schedule, and fees on the official websites application page.
