Ishigakijima Astronomical Observatory

Ishigakijima Astronomical Observatory is a research station located on Mount Maesedake equipped with a large optical-infrared telescope designed for observing and studying celestial objects. The facility features viewing areas and educational displays that allow visitors to explore the night sky and understand astronomical research conducted here.

The facility was established in 2002 and began operations in 2006 as a research center for studying the night sky from this southern Japanese island. Since opening, it has grown to become an important center for astronomical research and education in the region.

The observatory serves as a gathering place where locals and visitors come together for evening stargazing events, creating a shared experience around astronomy. This role has made it part of the community's connection to the wider cosmos.

The site has visitor centers with educational displays open during designated hours for public access and stargazing sessions. Check weather conditions before visiting, as clear skies are essential for meaningful observations of the night sky.

The facility operates the Southern Cross Monitor project, providing live webcam images of the Crux constellation as seen from this southern Japanese location. This makes it a rare example of a research station that shares continuous online observations of a celestial formation that holds special significance from this latitude.
