"With his closest friend, Matahachi, Takezo (the town's wild, orphan kid) leaves his village to join an army on its way to battle. After their side loses, they seek shelter in the isolated home of a widow, Oko, and her daughter, Akemi. Oko seduces Matahachi, who forgets his betrothal to the virtuous Otsu. Oko, Matahachi, and Akemi go to Kyoto, but Takezo returns to the village. Matahachi's family rejects Takezo's report and has him arrested for treason. A monk rescues him from death and sentences him to the study of the samurai code. Otsu and Takezo fall in love, and she promises to wait for him when he sets off on the road as a knight errant."

"Miyamoto eventually wrote a book about his knowledge of the sword, The Book of Five Rings, which in translation became a favorite of stockbrokers and businessmen in North America in the 1980s (it was published in 1982 in paperback by The Overlook Press of Woodstock, New York)."

this is a great movie do you have any others with the same actor? I believe he is in Yojimbo and The Seven Samurai.
