紀伊国
The , also known as or , was a "han" or Japanese feudal domain in Kii Province. The domain spanned areas of present-day Wakayama and southern Mie prefectures, and had an income of 555,000 koku. The domain was administered from Wakayama Castle in present-day Wakayama, Wakayama Prefecture. The heads of the domain were drawn from the Kishu-Tokugawa clan, one of the Gosanke, or three branches of the Tokugawa clan. The domain was founded by Tokugawa Yorinobu, the tenth son of the shōgun Tokugawa Ieyasu, when he moved from Sunpu Domain in Suruga Province to Kii Province. The Kishū came to control the smaller adjacent Tanabe and Shingū domains. The Kishū Domain was noted for its production of the "Kishū" mikan, soy sauce, lacquerware, and high-grade oak charcoal during the Edo period, and leather and cotton production by the Meiji Restoration in 1868.
