TheType 95 heavy tank (Japanese:九五式重戦車, kyūgo-shiki jūsensha), also known as the Type 95Ro-Go,[3] was the final result of Japanese multi-turreted tank design and was in commission during the time period betweenWorld War I andWorld War II. The main armament was a Type 94 70 mm cannon in a central turret, with its secondary front auxiliary turret mounting a 37 mm gun and a 6.5 mm machine gun in the rear auxiliary turret. Four prototypes were produced in 1934.[3][4]
After World War I, major powers around the world quickly adopted the revolutionary design of FrenchRenault FT light tank. One of the most successful features on the Renault FT was a 360-degree rotating turret. While developing new single-turreted tanks more closely based on the Renault FT, many countries, including Japan, also experimented with multi-turreted tank designs.[4]

The Imperial Japanese Army made the decision to develop heavy combat vehicles, which was prompted by the increasing threat posed by the Soviet Union, a potential enemy of Japan in East Asia. In 1931, Japan produced a prototype heavy tank that was designated theType 91 heavy tank. It was an 18-ton, three turret tank with a 6-cylinder gasoline engine producing 224 hp.[5] The Type 91 central turret had a Type 90 57 mm cannon as its main armament and a 6.5 mm machine gun. Its two smaller auxiliary turrets were each armed with a 6.5 mm machine gun. The tank had a maximum armour plate thickness of 17 mm; same as the priorType 87 Chi-I prototype.[6] It had seventeen road wheels on each side.[7] This first design was not successful, as it was considered to be underpowered, under-armed and lacked sufficient armour. The project was soon canceled. However, this project became a stepping stone in the development of the Type 95 heavy tank.[4]

The development of a new multi-turreted tank started in 1932 and was completed in 1934.[4] The overall shape of the Type 95 followed the design of the earlier Type 91, but it had thicker armour and its firepower was significantly improved. A more powerful inline 6-cylinder engine produced 290 horsepower.[4] Its suspension system was modified from that of the Type 91. While still using a leaf spring suspension, it had only nine road wheels on each side.[8]
Mounted in the central turret was the primary weapon, a Type 94 7 cm tank gun specifically designed for the Type 95 heavy tank. The cannon could fire both Type 92 high-explosive shells and Type 95 armor-piercing shells. The gun elevation angle was 20 degrees and gun depression angle was −12 degrees. A 6.5 mm machine gun was also mounted in the main turret. Its two additional turrets gave Type 95 yet more firepower: a Type 94 3.7 cm tank cannon was mounted in the front auxiliary turret, and the rear facing auxiliary turret featured a 6.5 mm machine gun.[4]
It was the largest Japanese tank at the time, weighing in at 26 tonne. Four prototypes were produced in 1934.[2][3] However, the multi-turreted tank concept was cancelled, so the Type 95 did not go into production. It proved to be a complicated design with poor mobility and had a lower top speed than desired.[2][9]

Two chassis were later used as platforms for:
