The Sword of Doom, known in Japan as Dai-bosatsu Tōge (大菩薩峠, "Great Bodhisattva Pass"), is a 1966 Japanese jidaigeki film directed by Kihachi Okamoto and starring Tatsuya Nakadai.

Two years pass, and in order to make a living, Ryunosuke joins the Shinsengumi, a sort of semi-official police force made up of rōnin that supports the Tokugawa shogunate through murder and assassinations.

In a botched assassination attempt, he sees another master swordsman, Shimada Toranosuke (Toshiro Mifune), in action, and for the first time he doubts that his own skill is truly unbeatable.

He kills her in the gardens, to the ominous cries of their sleeping child inside the house, and flees without keeping his appointment to duel with his pursuer.

'Great Bodhisattva Pass'), a novel that has remained popular since its initial release in 1913, a year after the death of the Emperor Meiji, "the ruler who oversaw Japan's transition from hermetically sealed feudal state to modern nation.

"[2] The novel originated from a newspaper serial, which appeared for three more decades; forty-one volumes were published before it was left uncompleted at the 1944 death of its author, Kaizan Nakazato.

[2] According to Geoffrey O'Brien, The Sword of Doom was an adaptation imposed on Kihachi Okamoto by Toho after the studio was dissatisfied with his film The Age of Assassins, which was completed in 1966 but only released in 1967.

[2] With "gaps and unresolved story lines" due to skipping some material, O'Brien noted that Okamoto's film might instead be called "Famous Scenes from 'Daibosatsu Toge'".
