[4] Then Japanese engineered their own version L2D2, by 1942, Nakajima had built, including the prototype, 71 L2D2 Navy Type 0 Transport Model 11s and then embarked on manufacturing combat aircraft of their own design.

Shōwa, once their factory and production line was complete, built the next series, a total of 416 aircraft, including 75 cargo versions with the "barn door," and reinforced floor (designated L2D2 1).

[4] Although the Japanese civil versions were nearly identical to their Douglas equivalent, the military variants, while visually similar, were substantially different.

The most radical changes to the original design came about due to wartime exigencies in shortages of strategic materials, that led to metal components in less critical structural areas being replaced by wood.

[5] The original DC-3s operated by Dai Nippon Koku KK were pressed into Imperial service during the war, serving alongside the license-built L2Ds.

[6] With the large load capacity inherent in all L2D variants, the types were used in all Japanese theaters, as both a passenger and cargo transport, playing an important role in supply of the distant garrisons on the islands of Pacific Ocean and New Guinea.

RAF Air Chief Marshal Sir Walter Cheshire was in charge of troop and supply airlift in South East Asia after Japan surrendered.

Tornij) Relatively few of the Shōwa/Nakajima L2Ds survived the war, although at least one captured example was in service with the National Aviation Corporation (CNAC) during 1945, serving along with DC-3s acquired pre-war.
