The Type 1 Self-Propelled Gun was produced from 1943, and around 140 were manufactured. Due to severe damage suffered during their transportation to the front line in the Philippines, a large number of Type 1s never actually made it into battle, but those that did are said to have been rated highly by the opposing U.S. forces. The Tamiya model kit faithfully captures all the details of this iconic self-propelled gun. Tamiya's designers have taken great care in researching archives and real world restorations to bring the avid modeler the most accurate scale model of the Type 1 self-propelled gun.
