Gunma Astronomical Observatory

Gunma Astronomical Observatory is a research facility in Takayama featuring a 150-centimeter reflector telescope and additional instruments for observing celestial objects. The site supports both scientific research and public visits.

The facility began operations in 1999 under astronomer Yoshihide Kozai, marking the start of its mission in astronomical research and observation. Its founding reflected growing interest in space study during that period.

The observatory brings together people interested in space to watch the night sky and learn about celestial objects through presentations and guided sessions. These gatherings create a shared experience centered on discovery and wonder.

The site is about 25 minutes by taxi from Jomo-Kogen Station and operates from 10 AM to 5 PM between March and October. Plan a visit during these months when weather and observation conditions tend to be most favorable.

The surrounding area follows specific light regulations designed to keep the night sky dark for optimal viewing conditions. This makes the observatory's location particularly valuable for clear observations.
