2026 Manno Astronomical Observatory Starry Sky Full-Day Course

Stargazing sessions at Manno Astronomical Observatory (まんのう天文台) are held every Friday, Saturday, and Sunday from April to November (using the astronomical observation room requires advance reservation). The 1st-floor exhibition room can be viewed without reservation (Fri/Sat/Sun 10:00-17:00; closed Dec 28-Jan 4). Located atop Mt. Okawa (大川山) at an elevation over 1,000m, it's a popular area for stargazing thanks to its few streetlights. Please check the official website for the latest schedule before visiting.
