Kounotori 3, also known as HTV-3, was the third flight of the Japanese H-II Transfer Vehicle. It was launched on 21 July 2012 to resupply the International Space Station (ISS) aboard the H-IIB Launch Vehicle No. 3 manufactured by Mitsubishi Heavy Industries (MHI) and JAXA. Kounotori 3 arrived at the ISS on 27 July 2012, and Expedition 32 Flight Engineer and JAXA astronaut Akihiko Hoshide used the International Space Station's Canadarm2 robotic arm to install Kounotori 3, to its docking port on the Earth-facing side (nadir) of the Harmony module at 14:34 UTC.

The H-II Transfer Vehicle (HTV), also called Kounotori , is an expendable, automated cargo spacecraft used to resupply the Kibō Japanese Experiment Module (JEM) and the International Space Station (ISS). The Japan Aerospace Exploration Agency (JAXA) has been working on the design since the early 1990s. The first mission, HTV-1, was originally intended to be launched in 2001. It launched at 17:01 UTC on 10 September 2009 on an H-IIB launch vehicle. The name Kounotori was chosen for the HTV by JAXA because "a white stork carries an image of conveying an important thing, therefore, it precisely expresses the HTV's mission to transport essential materials to the ISS". The HTV is very important for resupplying the ISS because after the retirement of the Space Shuttle it is the only vehicle that can transfer new 41.3 in (105 cm) wide International Standard Payload Racks (ISPRs) and dispose old ISPRs that can fit the 51 in (130 cm) wide tunnels between modules in the US Orbital Segment.
