Ashikaga Yoshihisa (足利 義尚, December 11, 1465 – April 26, 1489) was the 9th shōgun of the Ashikaga shogunate who reigned from 1473 to 1489 during the Muromachi period of Japan. Yoshihisa was the son of the eighth shōgun Ashikaga Yoshimasa with his wife Hino Tomiko.
Since the almost 30-year-old shōgun Yoshimasa had no heir by 1464, he adopted his younger brother Ashikaga Yoshimi to succeed him. However, Yoshihisa was born in the next year starting a struggle for succession between brothers that erupted into the Ōnin War starting in 1467, beginning the Sengoku period of Japanese history. In the middle of hostilities, Yoshimasa retired in 1473, relinquishing the position of Sei-i Taishōgun to Yoshihisa.
Significant events shape the period during which Yoshihisa was shōgun:
After the Ōnin war, Rokkaku Takayori, daimyō of southern Ōmi Province, seized land and manors owned by nobles of the imperial court, temples, and shrines. In 1487, Yoshihisa led a campaign (Rokkaku Tobatsu) against Takayori but died unexpectedly, leaving no heir.
Yoshihisa was followed by his cousin, tenth shōgun Ashikaga Yoshitane, the following year.
