It is the most Northern launch complex at Tanegashima, and along with the now inactive Osaki Launch Complex, it is part of the Osaki Range, used for orbital launches. The Yoshinobu complex consists of two launch pads, however launches have only been conducted from pad 1, which was built around 1993 for the H-II programme. The second pad was completed around 2000, shortly after the H-II was retired in favour of the H-IIA, but is yet to be used for a launch. The complex also contains a test stand for firing the LE-7 engines used in the first stage of the H-II and its derivatives. Prior to launch, rockets are processed vertically in the complex's vehicle assembly building. The rocket is rolled out to the launch pad on a mobile launch platform about twelve hours before it is scheduled to launch. It takes around thirty minutes to transport the rocket from the assembly building to Pad 1.
