Sanjuro
is a 1962 black-and-white Japanese jidaigeki film directed by Akira Kurosawa and starring Toshiro Mifune. It is a sequel to Kurosawa's 1961 Yojimbo.
Originally an adaptation of the Shūgorō Yamamoto novel Hibi Heian, the script was altered with the success of Kurosawa's 1961 Yojimbo to incorporate the lead character of that film.
