NAOJ Mitaka Campus, Astronomical research campus and museum in Mitaka, Japan
NAOJ Mitaka Campus is an astronomy research and education center in Tokyo that combines observatories, laboratory buildings, and exhibition spaces within a forested setting. The different areas spread across the grounds and include both active research facilities and spaces open for visitors to explore.
The site was founded in 1909 to provide astronomers with a location away from Tokyo's increasing light pollution. Throughout the 20th century, it grew to become Japan's leading center for observational astronomy and scientific research.
The site is named after pioneering astronomers and reflects how scientific work has shaped this place over generations. Walking through the grounds, you notice buildings that blend research activities with visitor spaces, showing how the community values both discovery and public education.
The grounds are open to visitors during set hours, with registration required at the guard station upon arrival. The site is walkable across varied terrain, and conditions change with the weather, so plan for outdoor exploration with appropriate clothing and footwear.
The grounds preserve an ancient burial mound from the Yayoi period, thousands of years old and situated among modern research buildings. This blend of archaeological remains and contemporary science shows how the site brings together different eras of human inquiry.
