is a 1980 film by Akira Kurosawa. In Japanese, kagemusha (lit. "shadow warrior") 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 daimyo in order to dissuade opposing lords from attacking the newly vulnerable clan. The daimyo is based on Takeda Shingen, and the film ends with the climactic 1575 Battle of Nagashino.
