National Astronomical Observatory of Japan

The National Astronomical Observatory of Japan (NAOJ) is an inter-university research institute within Japan's National Institutes of Natural Sciences. Established in 1988 and headquartered at Mitaka in Tokyo, it develops astronomical instruments, operates observing and computing facilities, and supports their open use by researchers across Japan and through international collaborations. Its research infrastructure spans optical and infrared observations with Subaru, radio astronomy through ALMA, Nobeyama and very-long-baseline interferometry, solar observations including Hinode, and computational astrophysics. NAOJ also participates in gravitational-wave research and the development of future observing facilities. Its Astronomy Data Center and research-support activities connect observations with scientific analysis, while its public programmes share astronomy with wider audiences.
