The Japan Space Exploration Agency (JAXA), which is responsible for research on space, planets, aviation research, spacecraft and satellite development, has developed a series of rockets, such as the H-IIB and H-IIA/B rockets, which have the capability to carry 8 tonne payloads into geostationary orbit (GTO) at maximum. Specifically in partnership with the private sector, Mitsubishi Heavy Industries built the Japanese experiment module launched on a space shuttle and added to the International Space Station, assembled and installed between 2007 and 2008, and also launched the H-II transport vehicle to carry payloads to the station in 2009.
