The center of a global observation and research network
The observatory was originally called the Tokyo Astronomical Observatory, located in Azabu, Minato-ku, but was moved to Mitaka Village in 1924, and in 1988 it was renamed the National Astronomical Observatory of Japan, a research facility jointly used by national universities.
Mitaka Campus is the center of a worldwide observation and research network that includes four locations in Japan, Hawaii, and Chile.
On the campus, cutting-edge research and the development of observation equipment are underway to capture a new image of the universe.
The beauty of the architecture can be seen from season to season.
It covers an area of about 260,000 square meters. Many observation instruments and buildings made from the Taisho era to the early Showa era are hidden among the greenery. They are valuable for learning about the history of astronomy and for their architectural beauty.
