Ashikaga Yoshiharu

Ashikaga Yoshiharu was born in Omi Province in 1511, the eldest son of the 11th shogun Ashikaga Yoshizumi, who was then in exile relying on the protection of the Omi Rokkaku clan. After his father's death, Yoshiharu was raised under the guardianship of the Harima steward Akamatsu Yoshimura, and in 1521, following the flight of the 10th shogun Ashikaga Yoshitane, he came of age and was installed as the 12th shogun of the Muromachi shogunate.

Yoshiharu's rule was marked by constant instability, caught between the rival deputy shoguns Hosokawa Takakuni and the Hosokawa Harumoto–Miyoshi Motonaga faction. After Takakuni's defeat at the Battle of Katsuragawa in 1527, Yoshiharu fled to Omi, only returning to Kyoto in 1534 through the mediation of Rokkaku Sadayori and his son Yoshikata — a pattern of repeated flight between Kyoto and Omi's Sakamoto and Kutsuki that defined his career. In 1536, the Tenbun Hokke Rebellion, a violent clash between Enryakuji on Mount Hiei and Nichiren-sect adherents in Kyoto, forced Yoshiharu to respond to further upheaval in the capital, and in his later years he struggled against the rising power of Miyoshi Nagayoshi, who supplanted the old deputy-shogun houses, making any real restoration of shogunal authority difficult. In 1546 he ceded the shogunate to his son Yoshifuji, later known as the 13th shogun Ashikaga Yoshiteru.

The Ashikaga shogunal house inherited a long tradition of collecting and preserving celebrated swords, including the Higashiyama Gomotsu treasures assembled under his grandfather Yoshimasa, and Yoshiharu stood within that lineage. Swords held by the shogunal house were sometimes bestowed upon daimyo as gifts, serving as instruments of political patronage and symbols of authority. In his personal life, Yoshiharu married a daughter of the regental noble Konoe Hisamichi, known as Keijuin, whose son by him became the 13th shogun Ashikaga Yoshiteru. Though remembered as a wandering shogun with little real power, Yoshiharu embodies both the hollowing-out of Muromachi shogunal authority and its persistence through the turbulent Sengoku period.
