National Astronomical Observatory of Japan (NAOJ) is an astronomical research organisation comprising several facilities in Japan, as well as an observatory in Hawaii. It was established in 1988 as an amalgamation of three existing research organizations - the Tokyo Observatory of University of Tokyo, Mizusawa Latitude Observatory, and a part of Research Institute of Atmospherics of Nagoya University.

When the national research organisations were again reformed in 2004, NAOJ became a division of the National Institutes of Natural Sciences.

The Headquarters, all of the NAOJ divisions, its Public Relations Center, the Astronomical Data Analysis Center, Advanced Technology Center, and the ALMA Office are located in Osawa, Mitaka, Tokyo, Japan.

The Subaru Observatory, one of the NOAJ divisions, is located in Hilo, Hawaii. The Nobeyama Radio Observatory (NRO) consists of two facilities, one for the study of Cosmic Radio and the other for Solar Radio (see radio astronomy), and are located in Minamimaki, Nagano. There are two other facilities located in Azumi, Nagano and Mizusawa, Iwate.
