Notes: Very few of these Japanese vehicles were built, perhaps 20 in all, as a decision was made to concentrate on production of the Type 75 self-propelled howitzer instead. The Type 74s that went into service were assigned to mountain units in the northern Japanese island of Hokkaido. In appearance, the Type 74 is similar to the British Abbot SPH. The driver is in the front right, and the rest of the crew in the turret to the rear. The turret has both roof and side hatches, two in the roof and one on each side for ammunition loading. The vehicle is amphibious with 3 minutes of preparation.

Notes: This is the standard Japanese self-propelled howitzer. The driver is at the front right, and radio operator directly behind him. The rest of the crew is in the turret. The turret has two hatches on the roof, and the hull has large ammunition loading doors in the rear. The commander and gunner are on the right of the gun, and the two loaders on the left. The ammunition is usually Japanese-made, but it can also fire NATO ammunition.
