About Sakamoto Observatory
Known locally by its full name, the Sakamoto-Hachiryu Astronomical Observatory (SHAO), the facility occupies a hilltop site within Hachiryu Mountain Nature Park, chosen for its elevated, semi-rural setting away from city lights.
History
The observatory was founded in 1997, giving the Yatsushiro area a dedicated public astronomy facility within its nature park.
Location & getting there
The site sits within Hachiryu Mountain Nature Park in Yatsushiro City, Kumamoto Prefecture. Visitors typically arrive via JR Sakamoto Station, then continue by taxi up to the observatory itself.
Visiting Sakamoto Observatory
We don't have confirmed public opening hours here; check with the observatory or the Yatsushiro city authorities before planning a visit, particularly given its hillside, taxi-only access.

The nature park setting and taxi-only access mean Sakamoto Observatory sits well clear of city glow - a promising spot for stargazing. If you've named a star, its position is listed in our catalogue; bring the coordinates along on a clear Kumamoto night.
Opening hours and public-visit programs vary by season. Check Google Maps for current times before you travel.
