Osaki Launch Complex is a rocket launch site located at the Tanegashima Space Center on the island of Tanegashima.

Initially constructed for the N-I rocket, the complex was subsequently utilized for N-II, H-I and J-I launches.

Constructed in the early 1970s to support N-I rocket launches, the facility underwent modifications in the 1980s to accommodate the N-II and H-I. It underwent extensive renovations in the early 1990s to support the J-I rocket, though the J-I was launched only once before the program's cancellation. In November 1998, the Osaki complex was used for a separation test involving an SRB-A solid rocket booster, which is utilized on the H-IIA launch vehicle.¹

The Osaki Launch Complex was deactivated in the mid-1990s, with operations shifting to the newer Yoshinobu Launch Complex located to the north.
