尾張國
In 1452, after the death of Shiba Yoshitake the vassals of the Shiba, like the Oda in Owari Province and the Asakura clan in Echizen Province, refused the succession of Shiba Yoshitoshi (1430–1490) and supported Shiba Yoshikado (died ca. 1480), and began to divide the large domains of their suzerains among themselves, and had become gradually independent in the domains which had been ceded to them. In 1475, the Oda had occupied the greater portion of Owari Province, but the Shiba would continue to try to regain authority until Shiba Yoshikane (1540–1600), who had to leave Owari.
