History of Toyota. Part 9 (1935-1939): Automobile Prototypes

Model AA Passenger Car and Model GA Truck Launched
The Toyoda Automatic Loom Works Model G1 truck was announced in November 1935 and sold by Hinode Motors, the first dealer, starting in December. That year, a total of 14 trucks were sold.
Initially, the Model G1 truck experienced a large number of rear axle housing failures.1 The Ford truck rear axle housing that had been sketched used flash-butt welding to join the pipe that made up a portion of the housing and the flange, and the contact surfaces of the two parts were joined entirely by welding. The welds, however, were not noticed and the housing was joined by gas welding on the exterior surfaces of the joints only. As a result, the gas welded portions were so weak that they often broke while being shipped to Nagoya. The problem was resolved by designing the pipe and flange to be joined by shrink fitting.
This was one example of a defect, and the defects were addressed one by one. With regard to the initial quality defects, Kiichiro Toyoda made the following statement. "Since this was the first domestically produced vehicle, we relied on the understanding and support of automobile industry companies, and the first vehicles that we shipped were hardly usable by today's standards. However we were fortunate to not suffer any major problems. This, of course, would not have been possible without our best efforts, but the various aid we received for our first domestic vehicle was also a large part of our success.

The Model G1 truck and Model A1 passenger car were improved to become the Model GA truck and Model AA passenger car. An automotive assembly plant was constructed at a site about one kilometer northeast of the Toyoda Automatic Loom Works head office in May 1936 to assemble the Model GA truck and Model AA passenger car. When the automobile assembly plant was completed, the body prototype plant was converted into a stamping plant, and stamped parts were shipped to the new body plant for assembly. In addition, manufacturing processes related to engines, powertrains, and suspensions performed at the Toyoda Automatic Loom Works head office plant were collectively referred to as the 'manufacturing plant,' and the various components were shipped from there to the automobile assembly plant.
When production at the Kariya automobile assembly plant came online, an exhibition to commemorate the completion of what it called the 'Toyoda Domestically Made People's Car' was held at the Tokyo Commercial & Industrial Museum in Marunouchi, Tokyo from the 14th to 16th of September 1936, when monthly production exceeded 100 units. On display were 15 vehicles including four Model AA passenger cars, two Model AB Phaetons, and a Model GA truck, a Model DA bus chassis, a fire truck, a military truck, and a dump truck with a winch (Table 1-4).

Toyoda Automatic Loom Works Designates a Licensed Company under the Automotive Manufacturing Industries Law
In the early 1930s, the Japanese automotive market was dominated by vehicles assembled by Ford-Japan and GM-Japan. Even before Ford and GM entered the Japanese market, the Ministry of War supported the manufacture of military trucks, but this did not lead to the development of a domestic automotive industry. Ford-Japan and GM-Japan steadily increased the volume of automobile parts imported from the United States for assembly, contributing to the expansion of Japan's trade deficit. The establishment of a domestic automotive industry became an urgent matter from the perspective of national defense as well.
The Ministry of Commerce and Industry created the Automobile Industry Establishment Research Committee within the Ministry in May 1931 and began investigating the plan for domestic automobile manufacturing. As a result, three private automakers were combined to design and manufacture automobiles according to Ministry standards, and nine prototype vehicles were completed in March 1932. The Ministry plan, however, collapsed two years later, and establishment of a national automotive industry was not achieved.
It was under these circumstances that Kiichiro Toyoda launched the Toyoda Automatic Loom Works automotive business in September 1933 and Yoshisuke Ayukawa established the Automobile Manufacturing Company (now Nissan Motor) in December of that year. As discussed above, the Ministry of Commerce and Industry and the Ministry of War gathered seven automobile manufacturing related companies in April 1934 to submit their opinions concerning the creation of domestic automotive industry, and at that time, Ayukawa presented the idea of establishing the domestic industry through an alliance with GM. The plan called for the creation of a tie-up with GM, the manufacture of automobile parts to start, and the nationalization of Chevrolet over 20 years.

Automobile Manufacturing Company's nationalization plan was not carried out because of opposition from the Ministry of War, but it led to changes in existing national policy. The government provided support to private companies that voluntarily developed domestic industry in accordance with the policies and conditions set by the government, rather than simply subsidizing private companies.
In order to determine these policies and conditions, the Ministerial Conference on Establishing an Automobile Industry was established and held its first meeting on August 10, 1934. The participating ministries included the Ministry of Commerce and Industry, Ministry of War, Ministry of the Navy, Ministry of Railways, Ministry of Finance, Ministry of Home Affairs, Resources Bureau, Ministry of Foreign Affairs, and Department of Overseas Affairs (the Ministry of Foreign Affairs and Department of Overseas Affairs participated starting from the 13th meeting).
At the seventh meeting, held on September 4, 1934, Kiichiro expressed his opinions, as previously mentioned, while President Yoshisuke Ayukawa of Nissan Motor and President Tomonosuke Kano of Automobile Industries also shared their opinions. Chairman Koshiro Shiba of Mitsubishi Heavy Industries, Ltd. and Senior Managing Officer Bungo Shimoda of Kawasaki Motor testified at the sixth meeting on August 29, and Chairman Tamaki Makita of Mitsui Mining testified at the eighth meeting on September 7. The result was that Toyoda Automatic Loom Works and Nissan Motor, which actually begun plant construction with the aim of mass production of automobiles, were designated as the first licensed companies.

The Automotive Manufacturing Industries Law was promulgated on May 29, 1936 and came into effect on July 11.2 Toyoda Automatic Loom Works immediately applied for a license under the Law on July 23 and was designated a licensed company by the Ministry of Commerce and Industry on September 19. Nissan Motor was designated a licensed company on September 22. Later, Diesel Automobile Industry Co., Ltd. (previously Tokyo Automobile Industries Co., Ltd.) was designated on April 9, 1941 to become the third company licensed under the Automotive Manufacturing Industries Law.
When Toyoda Automatic Loom Works was designated under the law, the director of Ministry of Commerce and Industry's Engineering Bureau instructed the company to use domestically-produced materials and parts for automobile manufacture. The use of domestic parts became obligatory starting in 1938.

When the Automotive Manufacturing Industries Law came into effect, assembly production by Ford-Japan and GM-Japan became difficult to maintain. Production volumes were limited and duties on imported parts were sharply increased, including an increase of the duties on engines from 35 percent to 60 percent of the value. As a result, Ford-Japan sought to establish alliance with Toyota Motor Co., Ltd. and Nissan Motor and conducted negotiations in 1938 and 1939, but no agreement was reached. In the end, Ford-Japan and GM-Japan had to suspend production in 1939.
