Postwar
Japan accepted the Potsdam Declaration on August 14, 1945, which brought the war to an end on the following day, August 15th in Japan. Postwar Japan was occupied by GHQ (General Headquarters). In terms of the automobile industry, GHQ did not allow a Japanese automobile company to make passenger cars – only trucks. Despite the difficulties, Kiichiro continued to push forward. He took a leadership role and acted to restart the Japanese automotive industry. First, in November 1945, he established an umbrella organization for the automotive industry (自動車統括団体) and he became the chairman of the organization. In the following year, he negotiated with GHQ himself, and made GHQ admit that the new situation was different from that of wartime. Kiichiro also invited representatives of distribution companies nationwide to Koromo. He gave speeches about policy changes at Toyota Motor Corporation and proceeded with talks for the recovery of the automobile industry. His forceful speeches impressed the representatives. These actions showed how much he was passionate about the automobile industry. After the war, many companies' dealers were released from control and became independent. Some of these dealers' companies restarted as Toyota dealerships and were able to support the company. This shows how much Kiichiro was trusted as the president of Toyota Motor Corporation by the owners of the dealerships. In fact, Kiichiro valued relationship with dealerships, so he usually communicated with people directly and dealt with problems as soon as possible.
However, producing and selling cars was still difficult. Raw materials and parts were not immediately available in the difficult period after the war, and it was harder to obtain cheap and high-quality genuine parts than before. The production of trucks did not reach the monthly production goal of 500 cars. In 1945, the annual production volume was 3275 units, and in the following year, 5821 units. Although the production of passenger cars was prohibited, research for passenger cars was allowed by the GHQ. Also, as a part of the occupation policy, the automobile company was contracted to repair United States military vehicles in Japan, which was a good opportunity for Toyota employees, including Kiichiro, to learn more about the engineering of American cars. They analyzed the advanced components of American cars to improve the development of their own passenger car. Kiichiro kept working hard to develop the Japanese automobile industry, even under the adverse circumstances of the postwar period.
In June 1947, GHQ approved the production of up to 300 passenger cars under 1500 cc per year. From that day on, Kiichiro started to work on passenger car production. In October 1947, the first Japanese passenger car after the war, the SA model with an S engine, was released and nicknamed "Toyopet." However, there were two mail problems during this period. First, these passenger cars did not sell well. This car was highly regarded in the automobile industry but not many people bought cars for leisure driving. Therefore, only 197 cars were sold over five years since it released, compared to 12,796 trucks sold over the same period. The second problem was that the production facilities were not good. There were many machines that had been used for many years and were not well maintained,. Kiichiro was worried that theToyota Motor Corporation cars could compete with foreign cars. Moreover, since there was a possiblility that Toyota Motor Company couldn't manufacture a car that would be better and cheaper than foreign cars in a few years and that Japanese people would be willing to buy, Kiichiro was thinking about working with a foreign car manufacturer. It is clear that Kiichiro aimed to build high quality, affordable passenger cars for Japanese people and improve their happiness.
