"KC-type"
From IH8MUD Wiki
November 1943 Production starts on the KC-type.
An update to the KB to make it even more suitable for war time production in times of limited material availability. Emphasis was on reducing the cost of materials. The engine cover was still metal but other body panels were made from plywood. The body design was extremely square, with only simple curves used on the engine cover and a flat radiator with no grill. Only a single headlight and only rear brakes were used.
The KC truck was used on Japanese military airfields to start aircraft engines. A power take-off was taken from after the gearbox. It rose behind the cabin and then projected forward. This was mated to the spinner on an aircraft's propeller to start the aircraft engine. Because it wasn't used for heavy cargo, the cargo bed was narrow and the rear wheels were singles instead of the normal doubles. Also, the cabin was very basic, having plywood sides, no doors and a canvas roof. Running boards were unique to the starter truck due to the narrow cargo bed. Hasegawa made a 1:72 scale plastic model of the KC starter truck labelled as "Starter Truck Toyota GB" , even although the real GB had a curved radiator grill and more complex bodywork.

Toyota KC is rumored to have been the base for production of the "AK-10".
Here is an overlay of the AK fender ontop of a KC photo:
...there is a strong resemblance and are definatly within the same family of truck.
Post-war the KC was still being produced for the rebuilding effort. Picture below is a KC that was built for the Postal Department after the war:
Here is another picture of a KC postwar:
