The IGS-Optical (Intelligence Gathering Satellite), built by Mitsubishi Electric (MELCO), is an optical reconnaissance satellite with a projected life of 5 years. The satellite will be operated by the Cabinet Satellite Information Center. The 850 kg IGS-Optical 1 is equipped with an optical sensor. The resolution is probably about 1 meter. The satellite serves both Japan's national defense and civil natural disaster monitoring.

H-IIA (H2A) is an active expendable launch system operated by Mitsubishi Heavy Industries (MHI) for the Japan Aerospace Exploration Agency. The liquid-fueled H-IIA rockets have been used to launch satellites into geostationary orbit, to launch a lunar orbiting spacecraft, and to launch Akatsuki, which studied the planet Venus. Launches occur at the Tanegashima Space Center.

The Japan Aerospace Exploration Agency (JAXA) is Japan's national aero-space agency. Through the merger of three previously independent organizations, JAXA was formed on 1 October 2003. JAXA is responsible for research, technology development and the launch of satellites into orbit, and is involved in many more advanced missions, such as asteroid exploration and possible manned exploration of the Moon. JAXA launch their Epsilon vehicle from the Uchinoura Space Center and their H-II vehicles from the Tanegashima Space Center.
