Japan's Space Development Program is planned and supervised by the Space Activities Commission, an advisory committee to the Prime Minister. Japan's space program is organized into two subprograms of activities, with the National Space Development Agency of Japan (NASDA) handling practical space applications and the Ministry of Education's Institute of Space and Astronautical Science (ISAS) handling the field of space science. 

NASDA was established on October 1, 1969, under the National Space Development Agency Law, to act as the nucleus for the development of space and promote the peaceful use of space. NASDA is part of the Science and Technology Agency. NASDA has developed Japan's H2 launcher, leads its space research and development programs, and oversees Japan's human space programs.

NASDA is responsible for: 

• Development of satellites (including space experiments and the space station) and launch vehicles, launching and tracking the craft. 

• Development of methods, facilities and equipment required for the above.
