The Japanese Defense Agency's Technical Research and Development Institution issued a requirement for a new APC to replace the Type 60 APC in 1967. Among the requirements included a maximum speed of over 60 km/h, ability to carry 12 men including the crew, to be fully amphibious, have all-welded aluminium armor, provision for the infantry to use their small arms from inside the vehicle and be armed with a 20 mm cannon, a 12.7 mm machine gun and a 7.62 mm machine gun. An automotive test rig, called the SUT, was built in 1968. Komatsu and Mitsubishi Heavy Industries each built two prototypes the following year, one each in steel and aluminium. Mitsubishi's aluminium model was chosen for use in December 1973.
