Ashikaga Yoshiharu (足利 義晴, April 2, 1511 – May 20, 1550) was the twelfth shōgun of the Ashikaga shogunate who held the reins of supreme power from 1521 through 1546 during the late Muromachi period of Japan. He was the son of the eleventh shōgun Ashikaga Yoshizumi. His childhood name was Kameomaru (亀王丸).
- May 1, 1521 (Daiei 1, 25th day of the 3rd month): After the tenth shogun Ashikaga Yoshitane and Hosokawa Takakuni struggled for power over the shogunate and Yoshitane withdrew to Awaji Island, the way was clear for Minamoto-no Yoshiharu to be installed as shogun.
- 1521 (Daiei 1, 6th month): Yoshiharu enters Kyoto.
- 1526 (Daiei 6, 12th month): Shōgun Yoshiharu invited archers from neighboring provinces to come to the capital for an archery contest.
Not having any political power and repeatedly being forced out of the capital of Kyoto, Yoshiharu retired in 1546 over a political struggle between Miyoshi Nagayoshi and Hosokawa Harumoto making his son Ashikaga Yoshiteru the thirteenth shogun.
- May 20, 1550 (Tenbun 19, 4th day of the 5th month): Yoshiharu died.
From a western perspective, Yoshiharu is significant, as he was shogun in 1543, when the first contact of Japan with the European West took place. A Portuguese ship, blown off its course to China, landed in Japan.
