Type 1 Ho-Ha

The Type 1 Ho-Ha was developed in 1941 as a result of a request from the army for a vehicle that could be used to transport a squad of infantry to the battlefield protected from enemy small arms fire. Despite experiences of the Second Sino-Japanese War, armored personnel carriers were viewed as too slow compared to wheeled trucks and there was not much effort for their development in the army.[1]

Production began in 1944 with the Type 1 Ho-Ha being an addition to the Type 1 Ho-Ki, an unrelated, yet similarly named armored tracked personnel carrier.[1][2] The half-tracked Type 1 Ho-Ha was built by Hino Motors in unknown quantities.[2][5]

The Type 1 Ho-Ha was based on the German Sd.Kfz. 251/1 (known popularly as Hanomag), the main armoured personnel carrier of the German Army, but did not use the overlapped and interleaved road wheels of the German design's suspension.[1][5] Further, it had a "vertical rear plate with a door", akin to the American M3 Half-track; however, the door itself was a copy of the German "two-leaf" design.[5]

The Type 1 Ho-Ha had a pair of road wheels in front, supported by a pair of short caterpillar tracks to the rear.[1] It was equipped with a tow coupling in the front and a towing hitch at the rear to haul artillery or a supply trailer. The maximum armor thickness was 8 mm with sloping armor plates. As with the Type 1 Ho-Ki, the hull was welded construction and it was "open-topped".[6]

The Type 1 Ho-Ha carried three Type 97 light machine guns as standard armament, one on each side, just to the rear of the driver's compartment and a third mounted to the rear as an anti-aircraft weapon.[1] All of these weapons had constricted firing arcs, which made firing directly forward or directly rearward impossible.[1]

The Type 1 Ho-Ha was initially deployed to China for operations in the ongoing Second Sino-Japanese War, but never in any great numbers. It was later deployed with the Japanese reinforcements in the Battle of the Philippines in 1944. Post-war, some Type 1 Ho-Ha half-tracks were modified by cutting off the rear armored section and replacing it with a flat bed. They were then used for reconstruction work in areas of the country.[7]
