shogun (hereditary military dictator) of Japan who was the 15th and last of his family to hold the title. Yoshiaki had been a priest, but in 1568, with the aid of his protector, the general Oda Nobunaga, he deposed his cousin Yoshihide and took over the shogunate. Subsequently, rivalry developed between Yoshiaki and Oda, and the latter deposed Yoshiaki and banished him from Kyōto in 1573.
