Miyamoto Musashi (1584 – 13 June 1645), also known as Shinmen Takezō, Miyamoto Bennosuke or, by his Buddhist name, Niten Dōraku, was a Japanese swordsman, philosopher, strategist, writer and rōnin, who became renowned through stories of his unique double-bladed swordsmanship and undefeated record in his 61 duels (next is 33 by Itō Ittōsai). Musashi, as he was often simply known, is considered a Kensei, a sword-saint of Japan. He was the founder of the Niten Ichi-ryū, or Nito Ichi-ryū.
