Otsu, just 10 miles from Kyoto, is Genkurō's last chance to kill Sadanobu.. The councillor is persuaded to hide in the inn's warehouse while Shintarō takes his place in his room. However, Genkurō is aware of the trick and captures Sadanobu and takes him to a boat, rows him off shore and offers him a choice of being killed or committing suicide. However, the other ninja in the boat turns out to be Shintarō who attacks Genkurō, they duel and Genkurō, mortally wounded by Shintarō's sword thrown into his back, kills himself. Sadanobu reaches Kyoto in safety and Tonbei offers to pray for those of his Iga gorup who were killed and Shintarō suggests they also pray for Genkurō and his group.
