Ashikaga Yoshiaki (5 December 1537 – 19 October 1597) was the fifteenth and final shogun of the Ashikaga shogunate in Japan, reigning from 1568 to 1573. His father, Ashikaga Yoshiharu, held the position of the twelfth shogun, and his brother, Ashikaga Yoshiteru, followed as the thirteenth shogun.
Born to Ashikaga Yoshiharu on 5 December 1537, Yoshiaki initially entered Kofuku-ji temple as a monk. However, when his elder brother Yoshiteru fell victim to the Miyoshi clan, Yoshiaki returned to secular life, assuming the name "Yoshiaki". During this time, the Ashikaga shogunate faced significant decline, with its authority largely disregarded throughout Japan. Nevertheless, various factions still vied for control of the central government, as it retained some prestige despite its weakened state. Ashikaga Yoshiteru made attempts to overthrow the Miyoshi, who effectively controlled him. Yet, his conspiracies led to a coup orchestrated by the Miyoshi and Matsunaga Hisahide, ultimately compelling Yoshiteru to take his own life. Subsequently, they attempted to install Ashikaga Yoshihide as the fourteenth shogun in Kyoto, but they struggled to maintain control over the capital.
Not until Ashikaga Yoshiaki secured the support of warlord Oda Nobunaga did an effective central authority return to Kyoto. In 1568, Oda's armies entered Kyoto, reinstating the Muromachi shogunate with Ashikaga Yoshiaki as a nominal shogun. This marked the onset of the Azuchi–Momoyama period. The fourteenth shogun, Yoshihide, was deposed without ever setting foot in the capital. In due course, Yoshiharu grew discontented with Oda Nobunaga's dominance and sought to reclaim state power.
In 1573, Ashikaga Yoshiharu sought the assistance of another warlord, Takeda Shingen, in overthrowing the Oda clan. In response, Oda Nobunaga deposed the shogun, compelling him to flee the capital. Most historians consider this the definitive conclusion of the Ashikaga shogunate. Yoshiaki embraced the life of a Buddhist monk, shaving his head and adopting the name Sho-san, later changed to Rei-o In. Nevertheless, Yoshiaki did not formally relinquish his shogunal title. Consequently, the Ashikaga shogunate's symbolic existence could be said to have persisted for several more years. Despite a restored central authority in Kyoto and Oda Nobunaga's efforts to unify the country, the power struggle among warring states persisted. Yoshiaki served as a focal point for anti-Oda forces. He even raised troops and dispatched them to engage Oda Nobunaga's army during the Ishiyama Hongan-ji War. Even after Oda Nobunaga's passing in 1582, the former shogun continued his endeavors to regain power.

Although Norikage himself was never a daimyo, he served as an advisor to three generations of Asakura clan leaders. He spent his entire life on military campaigns.

Asai (Azai) Nagamasa

Asai Nagamasa inherited power from his father, Asai Hisamasa, when he was only fifteen years old. Both brave and impulsive, he proved himself a capable commander, managing to regain lands from the Rokkaku clan that had previously been lost by his father. After a territorial dispute with Oda Nobunaga over the province of Mino, Nagamasa formed an alliance with Nobunaga and married his sister Oichi, who was famous for her beauty. In 1570, when Oda Nobunaga declared war on the Asakura family, Nagamasa sided with the Asakura because he had long-standing ties with them. This unexpected move threatened Nobunaga's invasion of the Asakura lands by threatening him from the rear. Oda managed to save his army, not without the help of Tokugawa Ieyasu, but relations between Nobunaga and Asai were permanently damaged.

Amago Tsunekisa

The Amago clan (also spelled Amako) was founded in 1392, when Sasaki Takahisa, who was orphaned at the age of three, took the new surname Amago, meaning “son of a nun,” in honor of the nun who raised him. Since the Sasaki family descended from Emperor Uda (866–931), the Amago clan traced its lineage back to this emperor. From around 1396, the Amago clan's headquarters was the mountain castle of Gassan-Toda in Izumo Province. Until the start of the Onin War, the Amago clan remained a minor clan in the service of the Kyogoku clan, which was also a descendant of the Sasaki clan. The Amago clan historically held the position of vice-governor of Izumo Province.
