1920s – 1930s

In 1924, Sakichi Toyoda invented the Toyoda Model G Automatic loom. The principle of jidoka, which means the machine stops itself when a problem occurs, became later a part of the Toyota Production System. Looms were built on a small production line. In 1929, the patent for the automatic loom was sold to the British company Platt Brothers, generating the starting capital for automobile development.

Under the direction of the founder's son, Kiichiro Toyoda, Toyoda Automatic Loom Works established an Automobile Division on September 1, 1933, and formally declared its intention to begin manufacturing automobiles on January 29, 1934. A prototype Toyota Type A engine was completed on September 25, 1934, with the company's first prototype sedan, the A1, completed the following May. As Kiichiro had limited experience with automobile production, he initially focused on truck production; the company's first truck, the G1, was completed on August 25, 1935, and debuted on November 21 in Tokyo, becoming the company's first production model. Modeled on a period Ford truck, the G1 sold for ¥2,900, ¥200 cheaper than the Ford truck. A total of 379 G1 trucks were ultimately produced.

In April 1936, Toyoda's first passenger car, the Model AA, was completed. The sales price was ¥3,350, ¥400 cheaper than Ford or GM cars. The company's plant at Kariya was completed in May. In July, the company filled its first export order, with four G1 trucks exported to northeastern China. On September 19, 1936, the Japanese imperial government officially designated Toyota Automatic Loom Works as an automotive manufacturer.

Vehicles were originally sold under the name "Toyoda" (トヨダ), from the family name of the company's founder, Kiichirō Toyoda. In September 1936, the company ran a public competition to design a new logo. Of 27,000 entries, the winning entry was the three Japanese katakana letters for "Toyoda" in a circle. However, Rizaburo Toyoda, who had married into the family and was not born with that name, preferred "Toyota" (トヨタ) because it took eight brush strokes (a lucky number) to write in Japanese, was visually simpler (leaving off the diacritic at the end), and with a voiceless consonant instead of a voiced one (voiced consonants are considered to have a "murky" or "muddy" sound compared to voiceless consonants, which are "clear").

Since toyoda literally means "fertile rice paddies", changing the name also prevented the company from being associated with old-fashioned farming. The newly formed word was trademarked and the company began trading on August 28, 1937, as the Toyota Motor Company Ltd. Kiichiro's brother-in-law Rizaburo Toyoda was appointed the firm's first president, with Kiichiro as vice-president. Toyota Automatic Loom Works formally transferred automobile manufacturing to the new entity on September 29.

The Japanese government supported the company by preventing foreign competitors Ford and General Motors from importing automobiles into Japan.

At the onset of World War II, Toyota almost exclusively produced standard-sized trucks for the Japanese Army, which paid one-fifth of the price in advance and the remainder in cash upon delivery.
