Bisei Observatory, Astronomical research center in Ibara, Japan
Bisei Observatory is an astronomical research center with a 101-centimeter telescope for observing stars, planets, and distant galaxies. The facility takes advantage of the dark and clear skies of Okayama Prefecture for its observation programs.
The facility opened on July 7, 1993, following the implementation of Japan's first Light Pollution Prevention Ordinance in Bisei Town in 1989. This measure created the foundation for quality sky observation in the region.
The region takes its name from two local rivers, Miyama and Hoshida, and three ancient shrines in the area commemorate fallen meteorites from the sky.
Access is available Friday through Wednesday between 9:30 and 22:00, allowing visitors to make the most of the dark sky conditions. When weather interferes with observation, the facility offers indoor activities to keep your visit worthwhile.
When cloudy skies make observation impossible, the facility presents a three-dimensional universe show called 4D2U on the ground floor. This immersive experience allows visitors to explore the wonders of space even during poor weather.
