Sanjuro , Tsubaki Sanjr? is a 1962 blackandwhite Japanese samurai film directed by Akira Kurosawa and starring Toshiro Mifune. It is a sequel to Kurosawas 1961 Yojimbo.

Nine young samurai, including his nephew, believe that the lord chamberlain, Mutsuta, is corrupt after he tore up their petition against organised crime and said maybe he himself was behind the crimes. One of them tells the superintendent of this and he agrees to intervene. As the nine meet secretly at a shrine and discuss their problem, a ronin Mifune emerges from another room where he has been resting. The ronin has overheard their plans, and suggests that the superintendent is in fact the real corrupt official. While at first the samurai are insulted by his claims, they soon find themselves surrounded by the superintendents men, proving that he was correct. The ronin hits a few of the attackers and bluffs their leader into leaving, taking only a small amount of money in reward to buy food because he is starving however, after realizing that Mutsuta and his family must now be in danger, he decides to help the samurai bring down the corrupt officials.When the samurai go to Mutsutas house, they find that he has been abducted and his wife played by Takako Irie and daughter Reiko Dan are imprisoned in the house. Following the ronins suggestion, a servant from the house gets the guards drunk, allowing the samurai to free the women. The group hide in a house next door to the superintendents compound, which contains a large number of camellia trees. Mutsutas wife asks the ronins name looking out of the window at the tsubaki camellia trees, which he can see over the fence separating the two properties, he declares his name to be Tsubaki Sanjr, adopting just as he had done in Yojimbo something he sees close by as a pseudonymous surname. notes The lady chastises Sanjuro for using his sword too frequently and insists that he refrain from unnecessary killing, noting that the best swordsmen keep their weapons in their sheaths. ........
