After the death of Ujisato in 1595, the territory went to Uesugi Kagekatsu. The Uesugi clan lost the territory as a result of the Battle of Sekigahara and were transferred to Yonezawa by the new Tokugawa shogunate. The shogunate created the 30,000 "koku" Miharu Domain for Katō Akitoshi, a younger son of Katō Yoshiaki in 1627. he was transferred to Nihonmatsu Domain the following year and replaced by Matsushita Nagatsuna, formerly of Nihonmatsu, who ruled until dispossessed in 1644. In 1645, the Akita clan was transferred from Shishido Domain in Hitachi Province, and the "kokudaka" of the domain was increased to 50,000 "koku". The Akita ruled until the Meiji restoration. During the Boshin War, although Miharu Doman was a member of the Ōuetsu Reppan Dōmei, the castle was surrounded without a fight to the Meiji government. After the Meiji revolution, all the remaining structures of the castle were removed, except for the main gate of the han school. The shape of the earthen ramparts largely remains and the area is used as a public park famed for its sakura trees in spring. The castle was listed as one of the Continued Top 100 Japanese Castles in 2017.
