A heavy tank project of the late 1950s. American technology and select intel on Soviet armored vehicles had a significant influence on its development. In contrast to American vehicles that used cast parts, the hull of the Japanese heavy tank was welded and had well-angled armor. At the same time, there were plans to use a cast turret with a large turret bustle. American experience was also drawn upon for the development of the guns. The project was never built.
