結城氏朝
The head of the Shimosa Yuki clan who fell after a year-long siege — central figure of the Yuki War
Description
Life
Yuki Ujitomo (1402-1441) was the 11th head of the Shimosa Yuki clan. Born the second son of Oyama Yasutomo, he was adopted as heir by his uncle Yuki Mitsuhiro, the 10th head, and succeeded to clan leadership.
The Yuki War
After Kamakura kubō Ashikaga Mochiuji took his own life following the Eikyō War (1438-1439), Ujitomo and his son Mochitomo took in Mochiuji's surviving sons, Shunnōmaru and Annōmaru, and rose in revolt against the Muromachi shogunate — the Yuki War of 1440. Ujitomo called on anti-shogunate forces across the Kanto region to join him, and warriors from Shimosa, Hitachi, and Shimotsuke gathered at Yuki Castle, its garrison said to have exceeded 10,000 at its height.
Fall of the Castle and Death
The shogunate's siege of Yuki Castle lasted roughly a year, but on April 16, 1441, Ujitomo and his son Mochitomo were defeated and killed in battle, and the castle fell. The two captured young princes were also killed during their subsequent transport.
Legacy
The Yuki War marked the last major resistance of forces loyal to the Kamakura kubō and significantly reshaped the political landscape of the Kanto region; Ujitomo's siege is remembered as an emblem of the Shimosa Yuki clan's defiance, commemorated today at the ruins of Yuki Castle in Yuki City, Ibaraki Prefecture.
