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.

Hatano Hideharu
Hatano Hideharu was the eldest son of Hatano Harumichi, the head of the Hatano clan. However, in childhood he was adopted by his uncle, Hatano Motohide, and was therefore formally regarded as Motohide’s heir. From the time of Hideharu’s grandfather, Hatano Tanemichi, the Hatano clan had been a vassal of the powerful Miyoshi house, which exerted considerable influence over the Ashikaga shoguns and effectively shaped the political situation in the region. Early in his career, Hideharu served Miyoshi Nagayoshi and, judging by surviving records, held a fairly high position within his lord’s hierarchy, as he was among the select group invited to the enthronement ceremony of Emperor Ōgimachi in 1557.

During the Ikkō-ikki uprising in Mikawa Province in 1563, having converted from the Jōdo Shinshū Buddhist sect to the Jōdoshū sect, he took part in suppressing the rebels. After these events, Masakatsu was appointed a military governor and was granted land holdings. According to a number of sources, he was one of the so-called “Three Governors of Mikawa” (Mikawa sanbugyō), together with Amano Yasukage (1537–1613) and Koriki Kiyonaga (1530–1608).

Tomoe Gozen
Gozen is regarded as one of the few historically documented examples of true female warriors of feudal Japan, known as onna-musha or onna-bugeisha. Although Japanese history records countless women who at various times were forced to take up arms—for example, in defense of their castles—Tomoe Gozen was, without any doubt, a genuinely skilled and accomplished fighter. She was the wife of Kiso (Minamoto) Yoshinaka, although The Tale of the Heike describes her more as a female vassal. Yoshinaka rose in rebellion against the Taira clan and, in 1184, captured Kyoto after his victory at the Battle of Kurikawa. After the Taira were driven into the western provinces, Yoshinaka began insistently asserting that he alone was worthy of assuming leadership of the Minamoto clan and taking on the mantle of its head.

Taira no Masakado
Taira no Masakado embodied the quintessential samurai of his era—self-assured, harsh, and unyielding. In his youth, he served in the palace guard and repeatedly proved his bravery while suppressing unrest. Thanks to these achievements, Masakado sought the post of chief of the capital’s military-police office (the kebiishi-chō), but he was rejected: by that time, nearly all court positions—now little more than privileged sinecures—were controlled by members of the powerful Fujiwara clan.
