Sasaki Kojirō

Sasaki Kojirō was a Japanese swordsman who may have lived during the Azuchi–Momoyama and early Edo periods and is known primarily for the story of his duel with Miyamoto Musashi in 1612, where Sasaki was killed. Although suffering from defeat as well as death at the hands of Musashi, he is a revered and respected warrior in Japanese history and culture. Later, Miyamoto proclaimed that Sasaki Kojirō was the strongest opponent he faced in his life.
