Yamaga Soko was a multifaceted figure in Japanese history, renowned as a strategist, philosopher, and scholar. Later in life, he became a ronin, leaving a significant mark on the understanding of the Tokugawa period samurai.
Born on September 21, 1622, in Aizu Wakamatsu, Yamaga's literary legacy includes notable treatises such as Bukyo, which delved into the essence of samurai creed, and Shido, focusing on the principles of gentlemanly conduct. Through his writings, Yamaga elucidated various aspects of samurai ethos, ranging from ethics and values to discipline, civic duty, etiquette, and philosophy. He advocated for a holistic approach to samurai training, integrating both martial prowess and intellectual depth.
Yamaga's influence extended beyond mere martial prowess; he played a pivotal role in transforming the samurai class from mere warriors to intellectual, political, and moral leaders during the early Tokugawa period. As a Confucian scholar and protege of Hayashi Razan, tutor to the first four Shogun, Yamaga reshaped the samurai identity, emphasizing the importance of intellect, ethics, and moral leadership.
Deeply rooted in nationalism, Yamaga's works celebrated Japan's virtues, imperial lineage, history, and culture. He intentionally employed the vernacular language over traditional Chinese literature to underscore his patriotic fervor. His writings served as a catalyst for 19th-century nationalist movements, igniting a renewed sense of pride in Japanese identity.
However, Yamaga's outspokenness eventually led to his banishment from Edo after the publication of Yamaga Gorui (Sayings of Yamaga) in 1665. This three-volume work, later republished as Seiyoyoroku (Record of Spiritual Teachings), was perceived as a challenge to Tokugawa authority. Subsequently, Yamaga found refuge in the service of the Asano clan of Ako, where he became an influential figure, inspiring future leaders like Oishi Kuranosuke, the revered leader of the 47 Ronin.
Yamaga Soko passed away in Edo on October 23, 1685, leaving behind a lasting legacy that continues to shape perceptions of samurai ethos and Japanese nationalism.

Hosokawa Sumimoto
Sumimoto came from the Hosokawa clan: he was the biological son of Hosokawa Yoshiharu and at the same time the adopted son of Hosokawa Masamoto, the heir of Hosokawa Katsumoto, one of the principal instigators of the Ōnin War. Masamoto was homosexual, never married, and had no children of his own. At first he adopted Sumiyuki, a scion of the aristocratic Kujō family, but this choice provoked dissatisfaction and sharp criticism from the senior vassals of the Hosokawa house. As a result, Masamoto changed his decision and proclaimed Sumimoto as his heir, a representative of a collateral branch of the Hosokawa clan that had long been based in Awa Province on the island of Shikoku. Almost immediately after this, the boy became entangled in a complex and bitter web of political intrigue.

Honda Masanobu
Masanobu initially belonged to the retinue of Tokugawa Ieyasu, but later entered the service of Sakai Shōgen, a daimyo and priest from Ueno. This shift automatically made him an enemy of Ieyasu, who was engaged in conflict with the Ikkō-ikki movement in Mikawa Province. After the Ikkō-ikki were defeated in 1564, Masanobu was forced to flee, but in time he returned and once again entered Ieyasu’s service. He did not gain fame as a military commander due to a wound sustained in his youth; nevertheless, over the following fifty years he consistently remained loyal to Ieyasu.

Honda Masazumi
Masazumi was the eldest son of Honda Masanobu. From a young age, he served Tokugawa Ieyasu alongside his father, taking part in the affairs of the Tokugawa house and gradually gaining experience in both military and administrative matters. At the decisive Battle of Sekigahara in 1600, Masazumi was part of the core Tokugawa forces, a clear sign of the high level of trust Ieyasu placed in him. After the campaign ended, he was given a highly sensitive assignment—serving in the guard of the defeated Ishida Mitsunari, one of Tokugawa’s principal enemies—an obligation that required exceptional reliability and caution.

Hōjō Nagaudji was one of the prominent military commanders of the late Muromachi period.

His origins remain unclear, but there is a possibility that he was connected to the Heiji clan of Ise Province, since early in his life he bore the name Ise Shinkurō.
