Ashikaga Yoshimitsu (born Sept. 25, 1358, Kyōto, Japan—died May 31, 1408, Kyōto) was a shogun (hereditary military dictator) of Japan, who achieved political stability for the Ashikaga shogunate, which had been established in 1338 by his grandfather, Ashikaga Takauji. The period of this shogunate’s rule (until 1573) subsequently became known as the Muromachi period after the district of Kyōto in which Yoshimitsu lived.
Proclaimed shogun in 1368, Yoshimitsu, in contrast to his father and grandfather, assumed an active role in the imperial bureaucracy. In 1381 he became inner minister, later advancing to the position of minister of the left and, in 1394, minister of state. By the end of his reign he had accomplished a complete reorganization of the civil government.
In 1392 Yoshimitsu ended an imperial division of Japan caused by Takauji’s seizure of Kyōto, which had forced the emperor Go-Daigo (reigned 1318–39) and his adherents to flee to the Yoshino Mountains, south of Nara, where they established a court separate from that of the emperor designated by Takauji in Kyōto. Yoshimitsu concluded a truce with the southern court, promising that the position of emperor would alternate between the two imperial lines if the imperial regalia would be returned to Kyōto. The promise was never kept. His hold over the countryside was not completely secure, however, and he had to deal with several serious revolts by provincial warrior groups during his reign. Nevertheless, by the beginning of the 15th century, Yoshimitsu was able to suppress the southwestern feudal lords, whose pirate ships were marauding the China coast, and he thereby ended a 600-year lapse in formal trade with China.
The reopening of trade with China was symbolic of a 75-year cultural renaissance in Japan that began in 1392 under Yoshimitsu. Court life assumed a luxurious air; high positions in government went to Zen Buddhist monks; and many magnificent temples and palaces were built, the most famous being the Golden Pavilion (Kinkaku-ji), which was built on the northwestern outskirts of Kyōto after Yoshimitsu’s retirement from the shogunate in 1394 in favour of his son.
