It was a larger design of the Daihatsu Class landing craft, with a bow ramp that was lowered to disembark cargo upon riding up onto the beach. It was constructed of a metal hull and powered by a diesel engine. Designed to carry a medium-sized tank or two eight ton tanks. The landing craft was used extensively to run troops and supplies to isolated garrisons, referred to as ant runs by the Japanese. The Allied air forces and U.S PT boats undertook increasingly successful raids at intercepting and destroying these craft towards the end of World War II.
