- National Astronomical Observatory of Japan
The National Astronomical Observatory of Japan (国立天文台 kokuritsu tenmondai ) (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 Astronomical Observatory of the University of Tokyo, International Latitude Observatory of Mizusawa, and a part of Research Institute of Atmospherics of Nagoya University.
In the 2004 reform of national research organizations, NAOJ became a division of the National Institutes of Natural Sciences.
