Sanada-Nobuyuki.jpg

Sanada Nobuyuki was a renowned samurai of the Sengoku period and the eldest son of daimyō Sanada Masayuki. He was the elder brother of the famous warrior Sanada Yukimura. Nobuyuki’s mother was Kansho-in, Masayuki's wife, and he was married to Komatsuhime (Inahime), the daughter of Honda Tadakatsu and the adopted daughter of Tokugawa Ieyasu. Nobuyuki also had two other wives: Seiin-in, his cousin, and Ukyo, the daughter of Tamagawa Hidemasa.

In his youth, Nobuyuki’s father served under Takeda Shingen and later his son, Takeda Katsuyori. To prove the Sanada clan’s loyalty to the Takeda, Nobuyuki was sent as a hostage. After the fall of the Takeda clan to the combined forces of Oda Nobunaga and Tokugawa Ieyasu, Nobuyuki escaped to Ueda Castle, the Sanada family stronghold.

In 1585, Tokugawa Ieyasu attacked Ueda Castle, but Nobuyuki, alongside his father Masayuki, successfully defended it in the Battle of Kami River. Later, as Masayuki aligned with Toyotomi Hideyoshi, Nobuyuki was sent to serve Tokugawa Ieyasu as a retainer to safeguard the Sanada clan’s future in case of conflict.

During the pivotal Battle of Sekigahara in 1600, Nobuyuki sided with the Tokugawa (Eastern Army), while his father and brother, Yukimura, fought for the Toyotomi (Western Army). After Ieyasu’s victory, Nobuyuki used his influence to save his father and brother from execution, though Masayuki and Yukimura were exiled to Kudoyama in Kii Province, and Nobuyuki was granted control of Ueda.

By 1614, tensions between the Tokugawa and Toyotomi clans flared again. During the Siege of Osaka, Yukimura escaped exile and joined Toyotomi forces to resist the Tokugawa. Despite his earlier efforts to protect his family, Nobuyuki was unable to save Yukimura, who died in battle.

Following the Siege of Osaka, Tokugawa Ieyasu held Nobuyuki in high regard. In 1622, he was made the first lord of the Matsushiro Domain, a position he held until his death at the age of 92.
