The siege of Kōzuki Castle (上月城の戦い, Kōzuki-jō no Tatakai) occurred in 1578, when the army of Mōri Terumoto attacked and captured the castle of Kōzuki in Harima Province. Kōzuki had been taken by Toyotomi Hideyoshi the previous year and entrusted to Amago Katsuhisa. When it fell to the Mōri, Amago committed hara-kiri. Amago's loyal and heroic general Yamanaka Yukimori was captured and executed.
