was the fifth shà Âgun of the Ashikaga shogunate who reigned from 1423 to 1425 during the Muromachi period of medieval Japan. Yoshikazu was the son of the fourth shà Âgun Ashikaga Yoshimochi.
Yoshimochi ceded power to his son, and Yoshikazu became Sei-i Taishà Âgun at age 18 by East Asian age reckoning, but he would die within two years. According to Oguri Hangan ichidaiki, Yoshikazu's death was hastened by a life of drunken dissipation. His buddhist name was Chà Âtoku-in (é·å¾Âé¢).
In 1423, Yoshikazu was appointed as shà Âgun. 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. The sixth official shà Âgun became Ashikaga Yoshinori in 1429.
The years in which Yoshikazu was shà Âgun are encompassed within a single era name or nengà Â.
