SECTION II -- OVERVIEW
Born in 1571 at Yagyū-no-shō in Yamato Province (modern Yagyū-chō, Nara City), Munenori inherited the Yagyū Shinkage-ryū from his father Yagyū Munetoshi (Sekishūsai).In 1601, at the call of Tokugawa Ieyasu, he entered Edo service and became sword instructor to the second shogun Hidetada.
In 1632, under the third shogun Iemitsu, he was promoted to ōmetsuke (great inspector) and given oversight of the bakufu's intelligence and covert-information organization.In 1632 he completed the Heihō Kadensho — the family treatise on the sword — and reframed the technique of swordsmanship from 'the sword that kills' to 'the sword that gives life' (katsujinken).
The Yagyū Shinkage-ryū became, under Munenori, the official sword of the Tokugawa shogunate; for the next two and a half centuries it remained the central school of warrior-class swordsmanship.He died at Edo in 1646, aged seventy-six.

SECTION V -- FIELD NOTES
[A]The Sword That Gives Life
In the Heihō Kadensho, Munenori distinguished the technique of the sword into the 'killing sword' (satsujinken) and the 'life-giving sword' (katsujinken). The accomplished swordsman, he argued, was the one who could win without killing — and that was the highest meaning of the art of war. The thought was deepened through his exchanges with the Rinzai Zen monk Takuan Sōhō, and went on to become a defining concept not only of the later Yagyū Shinkage-ryū but of Japanese martial-arts thought generally.
SECTION VI -- LEGACY & IMPACT
Munenori's central achievement was to lift a single sword school — the Shinkage-ryū — into the status of state doctrine, the official sword of the Tokugawa government. The Yagyū Shinkage-ryū became bakufu-recognized in his lifetime and remained at the center of warrior-class swordsmanship for the next two and a half centuries. The katsujinken thought of the Heihō Kadensho formed the philosophical spine of kendō, carried forward in the twentieth century by figures including Yamaoka Tesshū and Kanō Jigorō. The Yagyū family graves at Hōtoku-ji in Yagyū-chō are still visited by Shinkage-ryū practitioners today.
