Ashikaga Yoshimitsu was the third shōgun of the Ashikaga shogunate, ruling from 1368 to 1394 during the Muromachi period of Japan. Yoshimitsu was Ashikaga Yoshiakira's third son but the oldest son to survive, his childhood name being Haruō (春王). Yoshimitsu was appointed shōgun, a hereditary title as head of the military estate, in 1368 at the age of ten; at twenty he was admitted to the imperial court as Acting Grand Counselor.

The Muromachi period or Muromachi era , also known as the Ashikaga period or Ashikaga era , is a division of Japanese history running from approximately 1336 to 1573. The period marks the governance of the Muromachi or Ashikaga shogunate, which was officially established in 1338 by the first Muromachi shōgun, Ashikaga Takauji, two years after the brief Kenmu Restoration (1333–1336) of imperial rule was brought to a close. The period ended in 1573 when the 15th and last shogun of this line, Ashikaga Yoshiaki, was driven out of the capital in Kyoto by Oda Nobunaga.
