Directed by Kazuya Shiraishi, Bushido stars Tsuyoshi Kusanagi as Kakunoshin Yanagida, a disgraced samurai living in poverty with his daughter after being falsely accused and expelled from his clan. His exceptional skill at the game of Go brings him into contact with a wealthy merchant, but a new accusation and the discovery of the truth behind his downfall place his honour and restraint under increasing pressure. Inspired by a classic rakugo story, the film combines Edo-period drama, samurai tradition and a gradually unfolding tale of justice and revenge
