The Japanese space program (Japanese: 日本の宇宙開発) originated in the mid-1950s as a research group led by Hideo Itokawa at the University of Tokyo. The size of the rockets produced gradually increased from under 30 cm (12 in) at the start of the project, to over 15 m (49 ft) by the mid-1960s. The aim of the original research project was to launch a man-made satellite.

By the 1960s, two organizations, the Institute of Space and Astronautical Science (ISAS) and the National Space Development Agency of Japan (NASDA), were developing their own rockets. After experiencing numerous failures in the 1990s and 2000s, ISAS and NASDA merged — along with the National Aerospace Laboratory of Japan (NAL) — to form the unified Japan Aerospace Exploration Agency (JAXA) in 2003.
