Early years

In 1904, Torao Yamaha produced the first domestically manufactured bus, which was powered by a steam engine. In 1907, Komanosuke Uchiyama produced the Takuri, the first entirely Japanese-made gasoline engine car. The Kunisue Automobile Works built the Kunisue in 1910, and the following year manufactured the Tokyo in cooperation with Tokyo Motor Vehicles Ltd. In 1911, Kaishinsha Motorcar Works was established and later began manufacturing a car called the DAT. In 1920, Jitsuyo Jidosha Seizo Co., founded by William R. Gorham, began building the Gorham and later the Lila. The company merged with Kaishinsha in 1926 to form the DAT Automobile Manufacturing Co. (later to evolve into Nissan Motors). From 1924 to 1927, Hakuyosha Ironworks Ltd. built the Otomo. Toyota, a textile manufacturer, began building cars in 1936. Most early vehicles, however, were trucks produced under military subsidy. Isuzu, Yanmar and Daihatsu initially focused on diesel engine development.

Cars built in Japan before World War II tended to be based on European or American models. The 1917 Mitsubishi Model A was based on the Fiat A3-3 design. (This model was considered to be the first mass-produced car in Japan, with 22 units produced.) In the 1930s, Nissan Motors' cars were based on the Austin 7 and Graham-Paige designs, while the Toyota AA model was based on the Chrysler Airflow. Ohta built cars in the 1930s based on Ford models, while Chiyoda and Sumida, a predecessor of Isuzu, built cars resembling General Motors products 1935 Pontiac, and 1930s LaSalle.^[2][3]

Automobile manufacture from Japanese companies was struggling, despite investment efforts by the Japanese Government. The 1923 Great Kantō earthquake devastated most of Japan's fledgling infrastructure and truck and construction equipment manufacturing benefited from recovery efforts. Yanase & Co., Ltd. (株式会社ヤナセ Yanase Kabushiki gaisha) was an importer of American-made cars to Japan and contributed to disaster recovery efforts by importing GMC trucks and construction equipment. By bringing in American products, Japanese manufacturers were able to examine the imported vehicles and develop their own products.

Transportation and mobilization in the early 1900s was largely monopolized by the Japanese Government's Ministry of Railways, and private automobile companies emerged to further modernize the transportation infrastructure.

From 1925 until the beginning of World War II, Ford and GM^[4] had factories in the country and they dominated the Japanese market. The Ford Motor Company of Japan was established in 1925 and a production plant was set up in Yokohama. General Motors established operations in Osaka in 1927. Chrysler also came to Japan and set up Kyoritsu Motors.^[5] Between 1925 and 1936, the United States Big Three automakers' Japanese subsidiaries produced a total of 208,967 vehicles, compared to the domestic producers total of 12,127 vehicles. In 1936, the Japanese government passed the Automobile Manufacturing Industry Law, which was intended to promote the domestic auto industry and reduce foreign competition; ironically, this stopped the groundbreaking of an integrated Ford plant in Yokohama, modeled on Dagenham in England and intended to serve the Asian market, that would have established Japan as a major exporter^{[citation needed]}. Instead by 1939, the foreign manufacturers had been forced out of Japan. Under the direction of the Imperial Japanese Government, the fledgling vehicle production efforts were redirected to heavy duty truck production due to the Second Sino-Japanese War and the Isuzu TX was the result of three Japanese companies combining efforts to manufacture a standardized, military grade heavy duty truck.^[6][7]

During World War II, Toyota, Nissan, Isuzu and Kurogane built trucks and motorcycles for the Imperial Japanese Army, with Kurogane introducing the world's first mass-produced four-wheel-drive car, called the Kurogane Type 95 in 1936. For the first decade after World War II, auto production was limited, and until 1966 most production consisted of trucks (including three-wheeled vehicles). Thereafter passenger cars dominated the market. Japanese car designs also continued to imitate or be derived from European and American designs.^[8] Exports were very limited in the 1950s, adding up to only 3.1% of the total passenger car production of the decade.^[9]

1960s to today

In the 1960s Japanese manufacturers began to compete head-on in the domestic market, model for model. This was exemplified by the "CB-war" between the most popular compact sedans called the Toyota Corona and the Nissan Bluebird. While this initially led to benefits for consumers, before long R&D expenditures swelled and other companies offered competing compact sedans from Mazda, Subaru, Isuzu, Daihatsu and Mitsubishi. Towards the late 1980s and early 1990s Japanese automobile manufacturers had entered a stage of "Hyper-design" and "Hyper-equipment"; an arms race leading to less competitive products albeit produced in a highly efficient manner.^[10]

During the 1960s, Japanese automakers launched a bevy of new kei cars in their domestic market; scooters and motorcycles remained dominant, with sales of 1.47 million in 1960 versus a mere 36,000 kei cars.^[11] These tiny automobiles usually featured very small engines (under 360cc, but were sometimes fitted with engines of up to 600cc for export) to keep taxes much lower than larger cars. The average person in Japan was now able to afford an automobile, which boosted sales dramatically and jumpstarted the auto industry toward becoming what it is today. The first of this new era, actually launched in 1958, was the Subaru 360. It was known as the "Lady Beetle", comparing its significance to the Volkswagen Beetle in Germany. Other significant models were the Suzuki Fronte, Daihatsu Fellow Max, Mitsubishi Minica, Mazda Carol, and the Honda N360.

The keis were very minimalist motoring, however, much too small for most family car usage. The most popular economy car segment in the sixties was the 700-800 cc class, embodied by the Toyota Publica, Mitsubishi Colt 800, and the original Mazda Familia. By the end of the sixties, however, these (often two-stroke) cars were being replaced by full one-litre cars with four-stroke engines, a move which was spearheaded by Nissan's 1966 Sunny.^[12] All other manufacturers quickly followed suit, except for Toyota who equipped their Corolla with a 1.1-litre engine - the extra 100 cc were heavily touted in period advertising. These small family cars took a bigger and bigger share of an already expanding market. All vehicles sold in Japan were taxed yearly based on exterior dimensions and engine displacement. This was established by legislation passed in 1950 that established tax brackets on two classifications; dimension regulations and engine displacement. The taxes were a primary consideration as to which vehicles were selected by Japanese consumers, and guided manufacturers as to what type of vehicles the market would buy.
