The Samurai (1962)

Kongo's Revenge (9x5)

:

Kongō disguises himself as a shogunate messenger with a message for Genshin to gain an interview with him. After a brief bitchfest on the respective merits of Kōga versus Puppet ninja, Kongō claims that his real purpose in coming was to kill Genshin and take his place the better to kill Shintarō . He backs off when he sees the trapdoor at Genshin's feet. Shintarō gains access to Genshin, pretending to be captured by Yamizō in his guise as Tonbei. Genshin tells him of his plans to take control of Japan. Yamizō escapes and Genshin realises he is dealing with impostors, drops Shintarō through the trapdoor and pins Tonbei to the ceiling. However, Kongō frees them so he can kill Shintarō himself.
