13 Assassins is one of Takashi Miike's most restrained and mature movies. Set in Feudal Japan and based on true events, a venerable clan suffers under the reign of the cruel young Lord Naritsugu (Goro Inagaki), who commits atrocities at will. Unable to break their oaths, the samurai are torn between duty and shame. Some of the masters in the clan even go so far as to commit Seppuku in protest. Unable to endure the status quo, a plan is formed to gather a small team of the deadliest samurai and assassinate Lord Naritsugu while he is travelling between clan territories. The responsibility falls upon Shinzaemon Shimada (Koji Yakusho) to take on this potentially fatal task. The matter is further complicated by Lord Naritsugu’s personal bodyguard (and Shimada’s former rival) master samurai Hanbei (Masachika Ichimura), who is a force to be reckoned with.
