Kagemusha (影武者, Shadow Warrior) is a 1980 jidaigeki film directed by Akira Kurosawa. In Japanese, kagemusha is a term used to denote a political decoy. It is set in the Sengoku period of Japanese history and tells the story of a lower-class criminal who is taught to impersonate a dying daimyō to dissuade opposing lords from attacking the newly vulnerable clan. The daimyō is based on Takeda Shingen, and the film ends with the climactic 1575 Battle of Nagashino.
