, 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, style of swordsmanship, and in his final years authored The Book of Five Rings and Dokkōdō (獨行道, The Path of Aloneness).
Both documents were given to Terao Magonojō, the most important of Musashi's students, seven days before Musashi's death. The Book of Five Rings deals primarily with the character of his Niten Ichi-ryū school in a concrete sense, i.e., his own practical martial art and its generic significance; The Path of Aloneness, on the other hand, deals with the ideas that lie behind it, as well as his life's philosophy in a few short aphoristic sentences.
The Miyamoto Musashi Budokan training center, located in Ōhara-chō (Mimasaka), Okayama prefecture, Japan was erected to honor his name and legend.
The details of Miyamoto Musashi's early life are difficult to verify. Musashi himself simply states in The Book of Five Rings that he was born in Harima Province. Niten Ki (an early biography of Musashi) supports the assertion that Musashi was born in 1584: "[He] was born in Banshū, in Tenshō 12 [1584], the Year of the Monkey." The historian Kamiko Tadashi, commenting on Musashi's text, notes: "Munisai was Musashi's father ... he lived in Miyamoto village, in the Yoshino district [of Mimasaka Province]. Musashi was most probably born here."
Musashi gives his full name and title in The Book of Five Rings as Shinmen Musashi-no-Kami Fujiwara no Harunobu (新免武蔵守藤原玄信). His father, Shinmen Munisai (新免無二斎) was an accomplished martial artist and master of the sword and jutte (also jitte). Munisai, in turn, was the son of Hirata Shōgen (平田将監), a vassal of Shinmen Iga no Kami, the lord of Takayama Castle in the Yoshino district of Mimasaka Province.
