The H-IIB (H2B) was a Japanese expendable launch system jointly developed by JAXA and Mitsubishi Heavy Industries. It was used exclusively to launch the H-II Transfer Vehicle (HTV, or Kōnotori) cargo spacecraft to the International Space Station.
The H-IIB was a two-stage rocket powered by liquid hydrogen and liquid oxygen (hydrolox) engines, with four strap-on solid rocket boosters, and was launched from the Tanegashima Space Center in southern Japan. It could deliver up to to geostationary transfer orbit (GTO), compared with for its predecessor, the H-IIA. Its performance to low Earth orbit (LEO) was sufficient to carry the HTV.
