Sapporo Astronomical Observatory, Public astronomical observatory in Nakajima Park, Chuo-ku, Sapporo, Japan

Sapporo Astronomical Observatory stands on the summit of Okadayama hill inside Nakajima Park, at 1-17 Nakajima Park, Chuo-ku. It opened in 1958 as one of the facilities of the Hokkaido Grand Exposition and is run by the Sapporo Youth Science Museum. Its main instrument is an F12 refracting telescope with a 20-centimetre lens.

The observatory opened in 1958 as part of Japan's push for scientific education after World War II. It has remained a place where the public can access astronomy and observation since its establishment.

The observatory serves as a gathering place where visitors can watch the sky together and learn from knowledgeable staff. Regular sessions connect people with astronomy and make stargazing accessible to neighbors and families in the area.

The observatory sits about five minutes walking distance from Nakajima Park Station, making it easy to reach. Plan your visit during clear weather and check opening hours in advance to make the most of your time there.
