Yoshimochi ceded power to his son, and Yoshikazu became Sei-i Taishōgun at age 18,[2] but he would die within two years.[3] According to Oguri Hangan ichidaiki, Yoshikazu's death was hastened by a life of drunken dissipation.[4] His buddhist name was Chōtoku-in (長得院).
In 1423, was Yoshikazu appointed shōgun. A year later the Emperor Go-Kameyama dies. Yoshikazu would rule for a brief reign as he dies in 1425 and is succeeded by his father Yoshimochi that same year. When his father died in 1428, Go-Hanazono ascends the throne in second repudiation of agreement.[5] The sixth official shōgun became Ashikaga Yoshinori in 1429.[6]
