The Type 75 155mm self-propelled howitzer (75式自走155mm榴弾砲, nana-go-shiki-jisou-155mm-ryuudan-hou) is an armored artillery vehicle in the exclusive use of the Republic of Japan Army. Self-propelled howitzers are employed to provide mobile heavy fire support to army units in the field.
The Type 75 shares a number of automotive components with the Type 74 MBT which was developed during the same time. Mitsubishi Heavy Industries developed the chassis, while the howitzer and turret were designed by Japan Steel Works. Two prototypes were completed in 1971–72 and differed only in their loading systems. Trials were conducted 1973–74 and the howitzer was accepted for service in October 1975. It carries 28 rounds of ammunition on board.
