Takeda Katsuyori (1546 – April 3, 1582) was a Japanese daimyo of the Sengoku period, renowned as the head of the Takeda clan and successor to the legendary warlord Takeda Shingen. He was also the son-in-law of Hojo Ujiyasu. Katsuyori was born to Shingen and the daughter of Suwa Yorishige, known posthumously as Suwa-goryonin and by her real name, Koihime. His children included Takeda Nobukatsu and Takeda Katsuchika.
Initially known as Suwa Shiro Katsuyori, he succeeded to his mother's Suwa clan and established Takato Castle as his domain's seat. After the death of his elder brother Takeda Yoshinobu, Katsuyori's son Nobukatsu became the heir to the Takeda clan, making Katsuyori the de facto ruler. In 1581, Katsuyori built Shinpu Castle at Nirasaki and transferred his residence there.
Katsuyori's military career was marked by several significant battles:
- In 1569, he defeated Hojo Ujinobu during the Siege of Kanbara.
- In 1572, he captured a Tokugawa clan possession in the Siege of Futamata and participated in the Battle of Mikatagahara against the Oda-Tokugawa alliance.
- In 1573, following Shingen's death, Katsuyori led the Takeda family and continued to confront the Tokugawa clan.
- In 1574, he captured Takatenjin Castle, earning substantial support from the Takeda clan.
- In 1575, he suffered a severe defeat at the Battle of Nagashino, where Oda Nobunaga's innovative use of volley fire by 3,000 guns decimated Katsuyori's forces and killed many Takeda generals.
- In 1578, Katsuyori angered the Hojo family by supporting Uesugi Kagekatsu against Uesugi Kagetora, leading to the Battle of Omosu in 1580 against Hojo Ujimasa.
- In 1581, Katsuyori lost Takatenjin fortress to Tokugawa Ieyasu, resulting in the deaths of 680 men of the Okabe Motonobu garrison.
In 1582, Katsuyori faced further setbacks:
He lost Takato Castle to Oda Nobutada, marking the only Takeda stronghold in Shinano province to resist Nobunaga's final invasion.
Following these defeats, support from many clans, such as Kiso and Anayama, dwindled.
As the Oda-Tokugawa alliance advanced into Kai Province and laid siege to Shinpu Castle, Katsuyori, unable to hold the castle with his remaining men, set it ablaze and fled to Tenmoku Mountain. His forces were ultimately defeated at the Battle of Tenmokuzan. Katsuyori, his wife, and his son then committed ritual suicide (seppuku), marking the end of the Takeda clan. The nun Rikei documented his wife's suicide and composed several verses in their honor.
Katsuyori's personal life included two marriages. He first married Toyoma Fujin, the adopted daughter of Oda Nobunaga, who died giving birth to their son Nobukatsu in 1567. Katsuyori later married Keirin'in, the daughter of Hojo Ujiyasu, with whom he had a son and two daughters. In 1582, during their escape following Katsuyori's defeat by Oda Nobunaga, Keirin'in chose to die alongside Katsuyori rather than flee, committing jigai during the Battle of Tenmokuzan. Both of Katsuyori's sons also perished in the battle.

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.
