Toyotomi Hideyoshi
Shibata Castle was taken by Uesugi Kagekatsu, but in 1597, Toyotomi Hideyoshi moved the Uesugi clan to Aizu-Wakamatsu and assigned the former Shibata lands to Mizoguchi Hidekatsu in 1598. Hidekatsu had originally been a retainer of Niwa Nagahide, but after his death pledged fealty directly to Toyotomi Hideyoshi. After the death of Toyotomi Hideyoshi, he pledged fealty to Tokugawa Ieyasu, and was confirmed in his holdings by the new Tokugawa shogunate after the Battle of Sekigahara,
