Mizuno clan
The area of Yūki was an important center for the production of cotton, flax and woven goods from the Nara period. From the Kamakura period onwards, the area was controlled by the Yūki clan, who developed a castle town around Yūki Castle. This subsequently became the center of Yūki Domain which was ruled by 10 generations of a junior branch of the Mizuno clan under the Tokugawa shogunate in the Edo period.
