Economic activities in the civilian sector were extremely restricted during World War II and auto manufacturing was limited to military vehicles. Material shortages continued after the war's end in 1945, causing difficulties for the automobile industry.
Following the postwar dismantling of Japan's aircraft manufacturing industry, however, many workers from that industry moved to the automobile manufacturing sector. This laid the foundation for new technologies to emerge.
In November 1945, the first car rolled off Nissan Motor's production line and from 1946 on, sales of Datsun trucks, cars and other vehicles resumed.
Meanwhile, the Tokyo Electro Automobile Co. (later Prince Motors, Ltd.) was founded by engineers from the former Tachikawa Aircraft company. It began selling an electric car in 1947, helping to meet demand for taxis and other vehicles.
