The NAOJ Mitaka Campus is the headquarters of the National Astronomical Observatory of Japan (NAOJ), located in Mitaka City, Tokyo. This site serves as a critical center for astronomy, overseeing the management of observation facilities both in Japan and abroad, conducting astronomical research, developing new observational instruments, and providing education for graduate students. The campus also houses research and educational facilities for the Institute of Astronomy at the Graduate University for Advanced Studies (Sobrag) and the Astronomy Education and Research Center of the Graduate School of Science at the University of Tokyo, making it a major academic hub.
For the general public, certain areas and facilities can be visited without prior reservation. Additionally, the campus hosts regular or irregular events utilizing telescopes and digital theaters to provide immersive experiences. It is a truly precious location that represents the forefront of astronomical research and technological development.
The Mitaka Campus has a history that has grown alongside the development of Japanese astronomy. The grounds include architectural structures from the Taisho and Showa eras, some of which are designated as Registered Tangible Cultural Properties of Tokyo. Beyond being a mere research facility, it holds significant cultural value as a symbol of Japan's scientific and technological progress.
Furthermore, the site performs duties as the 'Ephemeris Calculation Office,' working alongside the National Institute of Information and Communications Technology (NICT) to perform highly precise tasks, such as determining leap seconds, utilizing data from facilities like the Mizusawa VLBI Observatory. This adds a layer of history to the site as a place that supports the very standards of time in our daily lives.
The campus features various facilities and exhibits related to astronomy. Through events using the digital theater, visitors can experience the vastness of space and deepen their astronomical knowledge. There are also specialized contact points, such as the Astronomical Information Center, which serves as a hub for professional information regarding celestial discoveries and astronomical inquiries.
Visits are generally limited to specific areas within the campus. By checking the provided maps, you can understand the layout of the various facilities. During special events, there may be exhibitions featuring telescopes located on-site or displays based on the latest astronomical technologies.
Activities at the NAOJ Mitaka Campus primarily take place during daytime hours. Since specific public events or programs involving digital theaters and celestial observations are held periodically, it is highly important to check the official website for schedules in advance. The environment is well-suited for experiencing both basic astronomical knowledge and the latest research results regardless of the season.
During your visit, you may be able to utilize materials such as 'Observation Worksheets' designed for elementary school students (availability subject to change). Using these can help deepen your understanding of astronomy and the role of the NAOJ from a more concrete perspective. Additionally, the campus grounds are available for public use via a reservation system for a fee.
The Mitaka Campus is located in Mitaka City, Tokyo, and is easily accessible via bus routes from Mitaka Station, Musashisakai Station, Chofu Station, Musashi-Koganei Station, and Komae Station. The surrounding area features many residential areas and cultural facilities, making it easy to spend time at a nearby cafe or park after gaining astronomical knowledge.
