Tsunetomo + Mitsushige

Samurai practiced age-structured homosexuality, known as shudō. Ordinarily a Samurai served his daimyo with honor, and was expected to follow his lord in death. However, Mitsushige disliked this custom and asked his beloved samurai, Tsunetomo, to reject it upon his own death. Ironically, this break with tradition led to the samurai code being written down; Tsunetomo lived to retire into the mountains, where he dictated to a young visiting samurai; His commentary became the Hagakure, a seminal guide to samurai culture.
