Research and development was started from 1985 as a successor for the older Type 75 self-propelled 155 mm howitzer.Japan Steel Works was the primary contractor, and developed the main gun and the turret.
The Type 99 uses a modified chassis from the Mitsubishi Type 89 IFV, lengthened with an additional road wheel. The Type 99 uses a 52 caliber barrel compared to the 39 caliber barrel on the Type 75 self-propelled howitzer.
Secondary armament of the Type 99 consists of a roof-mounted 12.7-mm machine gun, fitted with a shield.
Armor of the Type 99 provides protection against small arms fire and artillery shell splinters.
Vehicle is powered by a diesel engine, developing 600 horsepower. A traveling lock is provided at the front of the hull. It folds back onto the glacis plate when not in use.
The Type 99 self-propelled howitzer is resupplied from the Type 99 ammunition resupply vehicle.
