Lore & Background
Munetoshi's early life was marked by conflict. Legend claims that at age 15, he led a small troop defending Yagyū Castle against a massive Tsutsui army, but historical records do not support this account. After three days, the Yagyū capitulated and served the Tsutsui for eight years. Munetoshi studied martial and liberal arts, becoming proficient with spear and sword, as well as Confucianism, Zen Buddhism, and Shingon Buddhism.
In 1559, the warlord Matsunaga Hisahide recruited the Yagyū to overthrow the Tsutsui. Munetoshi received a citation for valor at the battle of Tōnomine, where he fought in the rearguard, was wounded, and killed several enemies. A retainer, Matsuda Muneshige, sacrificed his life to save Munetoshi's. In 1563, Munetoshi met Kamiizumi Hidetsuna and, after losing a match, became his disciple. Hidetsuna gave him an inka-jō, signifying highest attainment in Shinkage-ryū.
Munetoshi served Matsunaga and later Oda Nobunaga, but by 1577 he withdrew from battle and secluded himself in Yagyū Village to teach Shinkage-ryū. In 1594, Tokugawa Ieyasu arranged a meeting. Munetoshi demonstrated Mutō-dori, disarming Ieyasu and knocking him onto his back. Ieyasu asked to learn Shinkage-ryū, but Munetoshi refused due to age and recommended his son Munenori. Ieyasu agreed and signed an oath to favor the Yagyū.
Reader's Guide
Munetoshi's life shows a path from warrior to teacher. He studied many ryū but did not know victory until he met Kamiizumi Hidetsuna. After losing a match, he became Hidetsuna's disciple and trained for nearly a year. Hidetsuna gave him an assignment: research Mutō-dori, facing an armed opponent while unarmed.
Munetoshi devoted himself to this study and successfully demonstrated it on Suzuki Ihaku. Hidetsuna then gave him an inka-jō and later the Kage-mokuroku scrolls. In his Yagyū Kaken, Munetoshi wrote that he loved the military arts since youth and studied many ryū, but did not know victory until meeting Hidetsuna. After retiring, he taught Shinkage-ryū to his sons and other men.
Licenses from 1580 survive. In 1589 he wrote the Yagyū Kaken, a memoir and treatise. In 1593 he became a Buddhist lay priest, taking the name 'Sekishūsai Songon', and wrote the Heihō Hyakka, a collection of poetry on martial arts. His meeting with Ieyasu in 1594 secured the Yagyū's future with the Tokugawa.
