Under Tokugawa Ieyasu, the province was assigned as a feudal domain to his ninth son, Tokugawa Yoshinao with official revenues of 619,500 koku, the largest domain in the Tokugawa clan holdings outside of the shogunate itself. Yoshinao was founder of the Owari Tokugawa clan, one of the Gosanke, which had the hereditary right of succession to the position of shōgun should the main line fail. The castle town of Nagoya prospered during this period, and Owari Province was especially known for its ceramics industry.
