Kuma Kogen Astronomical Observatory

Kuma Kogen Astronomical Observatory is a facility located in the mountains of Kumakogen that combines stargazing with an indoor planetarium experience. The site sits at approximately 600 meters elevation and includes equipment designed for both casual observation and research purposes.

This facility opened in 1992 as an initiative to bring astronomy education to the local region. Over the decades it has developed into an active research and public engagement center.

The facility integrates into the Furusato Country Open Air Museum complex, connecting astronomical sciences with Japanese regional heritage and education programs.

Observation sessions are offered on specific nights when the facility opens for telescopic viewing. It is worth checking ahead about conditions and timing, since clear skies are essential for meaningful stargazing.

This site is known for regularly discovering asteroids, thanks to its mountain location with very little light pollution affecting observations. The clear viewing conditions at this elevation have made it valuable for ongoing research activities.
