Yagyū Shinkage-ryū
Yagyū Muneyoshi (1527-1606), the first famous Yagyū swordsman, fought for a number of different lords before meeting Tokugawa Ieyasu, the first Tokugawa shōgun. In 1563, he was defeated by the great swordsman Kamiizumi Nobutsuna, praised as one of the very few "Kensei" throughout Japan. Humbled by his defeat, Muneyoshi became Nobutsuna's disciple, and was later named his successor, founding the Yagyū Shinkage-ryū school of swordsmanship.
