Yoshikado Shiba was born in about 1465. He was a son of Yoshikane Shibukawa, Lord of Warabi Castle in Musashi Province (Saitama Prefecture).
When Yoshitoshi Shiba was deposed as head of the Shiba family by Shogun Yoshimasa Ashikaga (1459), he became the family head. After Yoshitoshi was pardoned by the Shogun (1463), he and Yoshikado fought for the family estate. Their feud was one of the factors which led to the Onin Civil War.
Yoshikado was backed in the feud by Mochitoyo (Sozen) Yamana, the father of his wife. In the Qnin War, Yoshikado belonged to the West Camp as commander of the forces from the Owari (Aichi Prefecture), Totomi (Shizuoka Prefecture) and Echizen (Fukui Prefecture) provinces who fought under Mochitoyo Yamana. They fought Katsumoto Hosokawa's and Yoshitoshi's East Camp forces.
In 1477, Yoshikado returned to Owari and lived in Kiyosu Castle. Yoshikado sent good-will missions to Korea on several occasions.
