The Nihon Aircraft Manufacturing Corporation (日本航空機製造 Nihon Kōkūki Seizō), or NAMC, was the manufacturer of Japan's only successful civilian airliner, the YS-11.
Although Japan had designed and manufactured a number of military aircraft during World War II, Japan was forbidden according to the Potsdam Declaration from engaging in the production of airplanes and other products that could be used to rearm a military. These restrictions, however, were lightened by the United States during the Korean War, opening up the possibility for a Japanese company to produce a civilian aircraft.
Actually a consortium of several different manufacturing companies and university professors, NAMC was founded in April 1957 by executives from Mitsubishi Heavy Industries, Fuji Heavy Industries, Shinmeiwa Manufacturing, Sumitomo, Japan Aircraft, Showa Aircraft, and Kawasaki Heavy Industries with the goal of designing and manufacturing a Japanese civilian turboprop airliner to replace the successful but aging Douglas DC-3. The resulting aircraft, the YS-11, became the only successful civilian airliner to come out of Japan in the 20th century and the only airliner designed and produced in Japan for over 50 years until the Mitsubishi Regional Jet made its maiden flight in 2015.
By the late 1970s, after producing several variations of the YS-11, NAMC hoped to introduce a jet airliner in order to compete with those being produced in the U.S. by companies such as Boeing and McDonnell Douglas. Unfortunately, because of the prohibitive cost of both manufacturing a jet engine in-house and also purchasing pre-fabricated engines from companies like Rolls-Royce, NAMC was forced to scrap its plans.
