Mifune](https://www.edgepedia.org/toshiro-mifune) as a destitute ronin who joins a band of Mito loyalists plotting to assassinate the shogunate's chief elder, [Ii Naosuke](https://www.edgepedia.org/ii-naosuke), at [Edo Castle](https://www.edgepedia.org/edo-castle)'s Sakurada Gate in 1860[1](https://eiga.com/movie/70205/) • [2](https://www.allcinema.net/cinema/141426). The film was produced by Toho together with Mifune's own company, Mifune Productions, and released in Japan on January 3, 1965, with a running time of 122 minutes[1](https://eiga.com/movie/70205/) • [3](https://www.nfaj.go.jp/wp-content/uploads/NFAJ2020No22.pdf).\n\n| Key fact | Detail |\n|---|---|\n| Original title / English title | 侍 (Samurai); released abroad as Samurai Assassin[1](https://eiga.com/movie/70205/) |\n| Release | January 3, 1965 (Japan), Toho; 122 minutes, black and white, Tohoscope[1](https://eiga.com/movie/70205/) • [4](https://silver.afi.com/movies/detail/0100003587/) |\n| Director / writer | Kihachi Okamoto; screenplay by Shinobu Hashimoto from Gunji Jiromasa's novel *Samurai Nippon*[2](https://www.allcinema.net/cinema/141426) |\n| Lead cast | Toshiro Mifune (Niiro Tsuruchiyo), Keiju Kobayashi (Einosuke Kurihara), Yūnosuke Itō (Kenmotsu Hoshino), Michiyo Aratama (Okiku/Princess Kiku), Koshiro Matsumoto (Ii Naosuke)[5](https://watch.plex.tv/en-GB/movie/samurai-assassin) |\n| Key crew | Cinematography Hiroshi Murai; music Masaru Sato; swordfight choreography Kuze Ryu[2](https://www.allcinema.net/cinema/141426) • [6](https://samuraidvd.com/samurai-assassin-blu-ray-edition/) |\n| Production | Toho and Mifune Productions' first joint production; Okamoto's first period film[3](https://www.nfaj.go.jp/wp-content/uploads/NFAJ2020No22.pdf) |\n| Audience rating | 7.4/10 on IMDb[7](https://web.playpilot.com/ca/movie/samurai-assassin-pptiDqZ/) |\n\n## Spoilers\n\n### Historical setting and plot\n\nThe story is drawn from the Sakurada Gate incident of 1860, in which Ii Naosuke of Hikone, the tairō (chief elder) of the [Tokugawa shogunate](https://www.edgepedia.org/tokugawa-shogunate) who had signed the 1858 Treaty of Amity and Commerce with the United States and carried out the Ansei purge against his critics, was assassinated outside the Sakurada Gate of Edo Castle[8](https://www.screenslate.com/articles/samurai-assassin) • [6](https://samuraidvd.com/samurai-assassin-blu-ray-edition/). In the film, on a snowy day in the first year of Man'en (1860), thirty-two ronin of the Mito clan led by Kenmotsu Hoshino wait at the gate to kill Ii as he travels to the castle; the plan fails when Ii does not appear, and the conspirators begin hunting a traitor among themselves[1](https://eiga.com/movie/70205/) • [2](https://www.allcinema.net/cinema/141426).\n\n**The central character.** Suspicion falls on two men: Niiro Tsuruchiyo, an impoverished ronin from Owari, and Einosuke Kurihara, an aristocratic samurai from Kōzuke who teaches at a town fencing hall and has a relative close to Ii[1](https://eiga.com/movie/70205/) • [2](https://www.allcinema.net/cinema/141426). Niiro, raised as an orphan without knowing his origins, is in fact the illegitimate son of Ii Naosuke by a concubine; he joins the assassination plot hoping to take the great elder's head and win samurai status, and at Sakurada Gate he cuts down Ii without knowing the man is his own father[9](https://tv.apple.com/jp/movie/%E4%BE%8D/umc.cmc.jdwyu7m0bf0h7062zaimvypj). The traitor is ultimately revealed to be the group's strategist, Sohei Masui[2](https://www.allcinema.net/cinema/141426).\n\n## Production\n\nThe screenplay adapts Gunji Jiromasa's novel *Samurai Nippon* (侍ニッポン), and the National Film Archive of Japan notes that this was the novel's fifth film adaptation, with substantial rewriting that built a weighty drama around the ronin's fate[3](https://www.nfaj.go.jp/wp-content/uploads/NFAJ2020No22.pdf). An earlier film had been released ten years before under the title *Samurai Nippon: Niiro Tsuruchiyo*[1](https://eiga.com/movie/70205/). Shinobu Hashimoto, the screenwriter of *Rashomon*, *Throne of Blood*, and *Harakiri*, wrote the script, and Hiroshi Murai shot the film in black-and-white Tohoscope[8](https://www.screenslate.com/articles/samurai-assassin). It was the first collaboration between Toho and Mifune Productions, and Okamoto's first time directing a period film[3](https://www.nfaj.go.jp/wp-content/uploads/NFAJ2020No22.pdf).\n\n## Style and action\n\nThe film's centerpiece is the mass swordfight in falling snow at Sakurada Gate, staged by the noted fight choreographer Kuze Ryu and cut together with the rapid editing that became Okamoto's signature[9](https://tv.apple.com/jp/movie/%E4%BE%8D/umc.cmc.jdwyu7m0bf0h7062zaimvypj). Okamoto, a Toho studio stalwart who worked across many genres and made his name as a specialist in action films with carefully choreographed violence, brought to the film a cynical view of war and politics informed by his own service as an enlisted soldier in World War II[8](https://www.screenslate.com/articles/samurai-assassin). The critic K. F. Watanabe describes the film as layered with ironies that expose the hypocritical nature of the samurai code and the feudal system, and notes that Okamoto developed the same idea further in *The Sword of Doom* (1966), which shares Murai and Hashimoto and likewise ends with an epic snow-bound sword battle[8](https://www.screenslate.com/articles/samurai-assassin).\n\n## Reception\n\nThe American critic Brendan Gill, reviewing the film in [The New Yorker](https://www.edgepedia.org/the-new-yorker) in March 1965, called it unquestionably one of the best Japanese films he had seen and an excellent film by any standard, while warning readers about its slow opening, its many brief flashbacks, and what he judged atrocious English subtitles[10](https://www.newyorker.com/magazine/1965/03/27/blood-and-tears-2). He judged the final scene, a desperate battle fought in a snowstorm outside a great lord's castle, among the most beautiful and terrible ever filmed, sufficient by itself to make the reputations of Okamoto and his photographer Hiroshi Murai[10](https://www.newyorker.com/magazine/1965/03/27/blood-and-tears-2). The [British Film Institute](https://www.edgepedia.org/british-film-institute) later included the film in its list of ten great samurai films, describing it as a strikingly shot dramatization of a defining moment in Japanese history and noting the difficulty Western viewers face in separating the film's fact from its fiction[11](https://www.bfi.org.uk/lists/10-great-samurai-films). On IMDb the film holds a rating of 7.4 out of 10[7](https://web.playpilot.com/ca/movie/samurai-assassin-pptiDqZ/).\n\n## Place in Okamoto's and Mifune's careers\n\nSamurai Assassin belongs to the run of samurai swordplay films through which Okamoto, unlike the more internationally famous [Akira Kurosawa](https://www.edgepedia.org/akira-kurosawa), focused on the political machinations of turbulent periods in Japanese history[8](https://www.screenslate.com/articles/samurai-assassin). Mifune's Niiro has been described as a gruffer version of the scruffy outcast samurai he played in *Yojimbo* (1961), a man whose crude exterior conceals a history of abandonment and whose pursuit of status destroys what he most desires[8](https://www.screenslate.com/articles/samurai-assassin). The film was followed a year later by Okamoto's nihilistic *The Sword of Doom*, made with the same cinematographer and screenwriter[8](https://www.screenslate.com/articles/samurai-assassin).\n\n## References\n\n1.
