Origins & Early Life

Yagyū Munenori (柳生 宗矩; 1571 – May 11, 1646) was a Japanese daimyō, swordsman, and martial arts writer. He founded the Edo branch of Yagyū Shinkage-ryū, which he learned from his father Yagyū "Sekishūsai" Munetoshi, and was one of two official sword styles patronized by the Tokugawa shogunate (the other one being Ittō-ryū). Munenori began his career in the Tokugawa shogunate as a hatamoto, a direct retainer of the Tokugawa house, and later had his income raised to 10,000 koku, making him a minor fudai daimyō (vassal lord serving the Tokugawa), with landholdings around his ancestral village of Yagyū-zato. He also received the title of Tajima no Kami (但馬守). Munenori entered the service of Tokugawa Ieyasu at a young age, and was later an instructor of swordsmanship to Ieyasu's son Hidetada.

Career & Major Achievements

He eventually became one of the primary advisors of the third shōgun, Iemitsu. Shortly before his death in 1606, Sekishusai passed the leadership of Yagyū Shinkage-ryū to his grandson Toshiyoshi. Following a period of musha shugyō, Toshiyoshi entered the service of a cadet branch of the Tokugawa clan that controlled the Owari province. Toshiyoshi's school was based in Nagoya and came to be called Owari Yagyū-ryū (尾張柳生流), while Munenori's, in Edo, the Tokugawa capital, came to be known as Edo Yagyū-ryū (江戸柳生流). Takenaga Hayato, the founder of the Yagyū Shingan-ryū, was a disciple of Yagyū Munenori and received gokui (secret teachings) of the Yagyū Shinkage-ryū from him.

Enduring Legacy & Impact

In about 1632, Munenori completed the Heihō kadensho (A Hereditary Book on the Art of War), a treatise on practical Shinkage-ryū swordsmanship and how it could be applied on a macro level to life and politics. The text remains in print in Japan today, and has been translated a number of times into English. Munenori's sons, Yagyū Jūbē Mitsuyoshi and Yagyū Munefuyu, were also famous swordsmen. The essay The Mysterious Record of Immovable Wisdom by Takuan Sōhō was a letter written from Sōhō to Munenori.
