The Type 74 105 mm self-propelled howitzer is only used by Japan. It shares a number of automotive components with the Type 73 Armored Personnel Carrier which was developed during the same time. Komatsu developed the chassis, while the howitzer and turret were designed by Japan Steel Works. The first prototypes were completed in 1969-70. The howitzer was accepted for service in 1974.
It carries 30 rounds onboard. It is amphibious when using the erectable flotation screen stowed around the periphery of the upper hull. It is equipped with a NBC filtration system.
As of 2001 Japan reported to the United Nations Office for Disarmament Affairs that 20 Type 74s were in service.[1] According to Jane's Armour and Artillery 2008, the 17 remaining Type 74s are attached to the 2nd Artillery Regiment at Asahikawa, Hokkaido.
