Since the G1 truck and the AA model were developed by the automotive division of Toyota Automatic Loom Works, Ltd. (before the division was spun off as Toyota Motor Corporation), the model names are preceded by the Toyota brand name.

In 1936, the Toyota car brand introduced a logo that marked a significant shift from its earlier emblem, reflecting the evolving ethos of the company. This logo featured the company's name in Japanese characters, "トヨタ自動車," prominently displayed within a stylized, circular frame. The circular motif symbolized the sun, alluding to Japan's "Land of the Rising Sun." It was a departure from the earlier three-oval logo and showcased the company's patriotic spirit. This change aimed to present Toyota as a distinctly Japanese brand, emphasizing its deep-rooted heritage and commitment to Japanese craftsmanship. The 1936 logo represented a pivotal moment in Toyota's branding, laying the foundation for its identity in the years to come.

In 1958, toyota redesigned its logo for the American market. Only red lettering outlined in broad strokes was used, with a white background. It was a simple and strict look, while at the same time explaining the brand's identity. By 1978, the font color had changed to red. The lines were bolder and more balanced.

In 1989, Toyota introduced a logo that represented a transformational phase in the brand's image. The logo retained the company name "Toyota" but adopted a more modern geometric design. The wordmark featured bold capital letters placed outside an oval border, symbolizing a sense of openness and global connectivity. The oval has been likened to the orbit of the earth, signifying Toyota's global presence and commitment to mobility on a global scale. The updated logo moves away from traditional Japanese symbolism and emphasizes Toyota's position as a contemporary international automotive leader. It symbolizes Toyota's ambition to transcend national boundaries and strengthen its position in the global automotive industry.
