Oda Nobutada (1557 – June 21, 1582) was a samurai and the eldest son of Oda Nobunaga, known for his active role in several battles during Japan's Sengoku period. He led armies under his father's command in campaigns against Matsunaga Hisahide and the Takeda clan.
Born around 1557 in Owari Province, Nobutada was the eldest son of Nobunaga (although there are theories about an older brother, Oda Nobumasa). His nanny was Jotoku-In, the daughter of Takigawa Kazumasu, a senior vassal of Nobunaga. There is also speculation that Nobutada was adopted by Nohime, Nobunaga’s wife. His childhood name was Kimyo-Maru, which means "strange" in Japanese. He initially took the name Oda Kankuro Nobushige before later changing it to Nobutada.
During the Eiroku era, the Oda clan formed an alliance with the Takeda clan through a marriage agreement between Nobutada and Matsuhime, the sixth daughter of Takeda Shingen. This strengthened the connection between the Oda and Takeda families. However, after Takeda Shingen began attacking Tokugawa Ieyasu’s lands, an ally of Oda, the alliance deteriorated. The engagement was eventually canceled following Shingen's death, contributing to the collapse of the Ashikaga shogunate in 1573.
Nobutada served Nobunaga in various battles, including the Ishiyama Hongan-ji War, the Siege of Iwamura Castle in 1574, and the attack on Ise Nagashima. In 1577, he achieved a significant victory by defeating Matsunaga Hisahide in the Siege of Shigisan. He also led the Siege of Takato in 1582, defeating Nishina Morinobu, a commander of the Takeda clan.
At the Battle of Nagashino in 1575, Nobutada began his career as a supreme commander, leading forces in various battles against the Takeda. His military successes earned him increasing responsibilities. Nobunaga entrusted Nobutada with controlling parts of eastern Mino and Owari provinces, and he became more prominent within the Oda clan’s hierarchy, receiving prestigious ranks and titles.
In 1582, Nobutada led a large force of 50,000 troops in the conquest of Kai Province, where he captured key Takeda strongholds such as Takato Castle. His rapid advance forced Takeda Katsuyori to retreat and ultimately commit seppuku, marking the end of the Takeda clan. After this victory, Nobunaga praised Nobutada and gifted him a sword, signaling Nobutada’s role as his intended successor.
However, in June 1582, Nobutada's fate took a tragic turn when Akechi Mitsuhide, one of Nobunaga's generals, launched a surprise attack on Nobunaga at Honno-ji in Kyoto. While Nobunaga was forced to commit suicide, Nobutada, staying nearby, was also attacked by Akechi’s forces and followed his father in committing seppuku.

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.
