真田信之

Sanada Nobuyuki (1566–1658), elder brother of the legendary Yukimura, made the defining decision of his life at Sekigahara: while his father Masayuki and brother Yukimura joined the western coalition, Nobuyuki sided with Tokugawa Ieyasu. This was almost certainly a calculated family survival strategy — insurance that whichever side won, at least one branch of the Sanada would survive. It worked: after Sekigahara, while Masayuki and Yukimura were exiled to Koyasan, Nobuyuki retained his domain and eventually established the Matsushiro domain in Shinano, which the Sanada governed for the remainder of the Edo period. His wife Komatsuhime, daughter of Honda Tadakatsu, was his match in force of character — famously she refused to allow her own father-in-law Masayuki to pass through her gate without her husband's permission, even as he was marching to war. Nobuyuki lived to ninety-three, the last surviving witness of the Sengoku generation, and maintained his martial disciplines — including daily sword practice — until very late in life. The swords he carried were those of a man who had chosen prudence over glory, endurance over the blazing death his brother chose; they are the swords of patience and survival rather than heroic sacrifice, a different but equally profound expression of the samurai spirit.
