Tokugawa Yoshinao, the ninth son of Tokugawa Ieyasu, was born in Osaka Castle on January 2, 1601. At the tender age of six, he was appointed as the master of Kiyosu Castle in Aichi Prefecture. In 1612, with the completion of Nagoya Castle nearby, eleven-year-old Yoshinao rose to become the Lord of Owari Domain and Nagoya Castle. Among the Tokugawa clans—the Kii, Mito, and Owari—Yoshinao's Owari Tokugawa clan held the most political and financial significance, positioning him favorably within the family.
Renowned for his swordsmanship, Yoshinao began training in the Yagyu Shinkage style under Yagyu Hyogonosuke. By the age of 21, he had risen to the rank of Soke, alongside Hyogonosuke, pioneering the distinctive Owari Yagyu Shinkage Ryu style with original techniques.
During the 1620s, the legendary swordsman Miyamoto Musashi visited Owari, introduced by Yagyu Hyogonosuke. Meeting Yoshinao at Nagoya's Ni-no-Maru Palace, Musashi showcased his Enmei Ryu two-sword style upon Yoshinao's request. After engaging in several bouts, Musashi emerged victorious in each encounter, earning Yoshinao's admiration and permission to establish a dojo in Nagoya. The dojo flourished, attracting over 3,000 samurai from Nagoya Castle until the mid-Meiji period.
The tradition of elaborate wedding parades in Nagoya traces back to Yoshinao and his wife, Haruhime's splendid procession through the city streets and into Nagoya Castle. The opulent Taimenjo living quarters of the Honmaru Palace were adorned with paintings depicting scenes of Wakayama, Haruhime's homeland, commissioned by Yoshinao to ease her transition to Nagoya.
Yoshinao's legacy also includes his role in co-creating the esteemed Ofuke-yaki pottery style. Collaborating with potters from Seto, he established a kiln within Nagoya Castle's Ofuke-maru precinct, producing exquisite white glazed pottery items such as tea bowls and caddies. These wares, presented by Nagoya Castle's lords to various daimyo across Japan, enhanced their prestige and value.
At the age of 49, Yoshinao passed away, likely due to a stroke, on June 5, 1560. His unique grave and mausoleum were established at Joko-ji in Seto, commemorating his significant contributions to the arts and culture of Nagoya.

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.
