When Yoshimori WADA raised an army to defeat the Hojo clan in 1213 (Battle of Wada), Chikaie sided with the Wada clan and was arrested by the army of the Kamakura shogunate (but he was sent alive to Kamakura, Sagami Province, because the shogunate army intended to show how brawny he was to the shogun family).
建保元年（1213年）、和田義盛が北条氏打倒の為、挙兵した際（和田合戦）、親家は和田氏軍に味方して出陣し、幕府軍に捕らえられた（将軍家に親家の力芸を観させる為、そのまま相模国鎌倉に送られた）。
