Type 73 has a weight of about 13.3 tons, a length of 5.8 m, a width of 2.8 m, and a height of 2.2 m. It was powered by a Mitsubishi 4ZF air-cooled V-type 4-cylinder diesel engine, with 300 horsepower. The vehicle can reach a top speed of 70 km/h, and has a range of 300 km.

The Type 73 is almost unique in that it uses a mid-engined V4 layout, as the driver and bow machine gunner are in the front of the vehicle. The commander sits slightly behind the bow gunner while the gunner sits behind the driver. The engine is mounted on the left side behind the bow gunner with both its air intake and exhaust on the top of the vehicle. The engine and transmission are designed to be easily removed as one complete unit.

The gunner’s cupola can traverse a full 360°, but the bow gunner’s weapon can only traverse, elevate and depress 30°. It is fitted with six smoke dischargers, three on each side. The Type 73 is not normally amphibious unless a special kit, including a trim vane on the front hull and side-slung buoyancy units, has been fitted but not all vehicles have this kit. It is propelled through the water by its tracks at a maximum speed of 7 km/h. The vehicle is fitted with infra-red driving lights and an NBC system.

Variants of the Type 73 include a Command version, with a raised roof. A special variant, the Type 73 self-propelled wind measuring station provides meteorological data for 130 mm multiple-launch rocket batteries. A total of 338 Type 73s have been produced and are still in service with the Japan Ground Self-Defense Force.
