The Ukita of Bizen Province were descended from Kojima Takanori, who was himself descended from the venerable Miyake family of Bizen Province. The 16th Century opened with the Ukita led by Ukita Yoshiie and vassals of the Urakami family. Yoshiie's grandson Naoie would come to usurp the Urakami and rule all of Bizen. Under Toyotomi Hideyoshi, the Ukita became very powerful in western Honshu but lost their domain following the Battle of Sekigahara in 1600.
