In Akira Kurosawa's classic 1980 film "Kagemusha" ("Shadow Warrior"), the 16th-century daimyo Takeda Shingen is mortally wounded by a sniper after being lured by the sound of a flute during a castle siege. Takeda's clan know that rival warlords Oda Nobunaga and Tokugawa Ieyasu will pounce on their domain once they realize he is dead, so a look-a-like is installed in his place to maintain the deception that he is alive. The domain they are desperately trying to protect was called Kai and its former capital is the city of Kofu in modern-day Yamanashi Prefecture.
