The history of the city of Toyota, located in Aichi Prefecture, is inextricably linked to the industrial development of Japan. Originally, this area was known as Koromo. During the Edo period (1603–1868), it served as the administrative centre of the feudal domain (han) of the same name, which defined its status as an important regional hub. The foundation of the region's early economy was agriculture and silk production; however, over time, this industry declined, giving way to a new industrial era.
A key moment in the city's history was the founding of the Toyota Motor Corporation in 1937. The establishment of the automotive giant's headquarters and main production facilities here completely changed the economic landscape of Koromo. The city began to grow rapidly, transforming from a quiet settlement into a major industrial node. This process was so comprehensive that the city and the company became practically synonymous.
The symbolic completion of this transformation was the official renaming of the city. On January 1, 1959, at the request of local authorities and in recognition of the achievements of the largest employer, the city of Koromo was renamed Toyota. This act cemented its new status as the "automotive capital" of the country, whose economy and identity today are almost entirely defined by the success and activities of the world-renowned auto concern.
