Ko Morofuyu, a key figure in the service of the first Ashikaga Shogun, Ashikaga Takauji, held crucial administrative and military roles in various provinces. Initially serving as the administrative governor of Mikawa Province (Aichi Prefecture) and the military governor of Musashi Province (Saitama Prefecture), he later assumed the governorship of Ise (Mie Prefecture). To ensure clan stability, he was adopted by his cousin, Ko Moronao.
During the Nanboku-cho period, characterized by the division of the Imperial court into Northern and Southern factions, Morofuyu aligned with the Northern court. He actively participated in actions against the court noble Kitabatake Akiie in Aonohara, Mono (Gifu Prefecture) alongside his cousin. In 1339, he became a direct councilor to the Shogun’s son and future shogun Ashikaga Yoshiakira in the Kanto region. His military successes led to his appointment as the Governor of Musashi. Following orders to return to Kyoto, he was later assigned as the governor of Ise, where he continued to distinguish himself in battles.
In 1349, Shogun Ashikaga Takauji sent his fourth son, Motouji, to control the Kanto regions, and Morofuyu, along with Uesugi Noriaki, was tasked with supervision due to Motouji's young age. However, during the subsequent Kanno Joran civil war (1350-1351), when Uesugi and the Shogun's brother defected to the Southern Court ruled by Emperor Go-Daigo, Morofuyu left his post in Kamakura. Engaging in battle with Uesugi Noriaki near Kamakura, Morofuyu suffered defeat. Forced to retreat to Suzawa Castle in Kai Province, he faced encirclement and, on February 13, 1351, chose to perform seppuku.

The Asakura family, who claimed kinship with several emperors, lived in the province of Echizen. Its representatives were considered hereditary vassals of the Shiba clan.

Asakura Yoshikage
Yoshikage was the eldest son of Asakura Takakage. He began ruling in 1548 at the age of fifteen, and during his reign he twice defeated the Ikko-ikki forces, in 1555 and 1564. Yoshikage supported the Saito family in their struggle against Oda Nobunaga in 1561–1567. When Ashikaga Yoshiaki fled Kyoto in 1565 after the assassination of his older brother, Shogun Ashikaga Yoshiteru, Yoshikage gave him refuge. However, he was unable to provide sufficient support for Yoshiaki's claim to the title of shogun, and Yoshiaki had to seek help from Oda Nobunaga.

Asakura Norikage
Norikage came from the ancient samurai clan of Asakura, whose members considered themselves descendants of Prince Kusakabe, son of Emperor Tenmu (631–686). He was the eighth son of daimyo Asakura Takakage and was named Kotaro in childhood. Over time, Asakura Norikage became the pillar of the Asakura clan and was undoubtedly its most talented commander during that difficult period when the clan was experiencing internal difficulties, uprisings by the Ikko-ikki sect, and instability in the lands surrounding the capital. 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. After his father's death in 1481, Norikage entered the service of his brother, Asakura Ujikage.

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.
