Miyamoto Musashi IV: The Duel at Ichijo-ji Temple (1964)

In 1879, Kenshin and his allies face their strongest enemy yet: his former brother-in-law Enishi Yukishiro and his minions, who've vowed their revenge.

A sadistic Daimyo (feudal lord) rapes a woman and murders both her and her husband, but even when one of his own vassals commits suicide to bring attention to the crime, the matter is quickly hushed up. Not only will there be no punishment, but because the Daimyo is the Shogun's younger brother, he will soon be appointed to a high political position from which he could wreak even more havoc. Convinced that the fate of the Shogunate hangs in the balance, a plot is hatched to assassinate the Daimyo. The two most brilliant strategic minds of their generation find themselves pitted against each other; one is tasked to defend a man he despises, and has a small army at his disposal. The other is given a suicide mission, and has 12 brave men. They are the 13 Assassins.

Official Shogunate executioner Ogami Itto has been framed for disloyalty to the Shogunate by the Yagyu clan, against whom he now is waging a one-man war, along with his infant son, Daigoro.

With most of his family already dead at Ogami Itto's hands, Retsudo launches one final plot to destroy him, and when that fails, unleashes the fury of every remaining member of the Yagyu clan.

Japan, 1860. The men of the Mito clan, victims of the Ansei purge, anxiously prowl around the Sakurada Gate of Edo Castle with the intention of assassinating Naosuke Ii of Hikone, tairō of the Tokugawa shogunate and responsible for their misfortune.

The mother of a feudal lord's only heir is kidnapped by the lord. Her husband and his samurai father must decide whether to accept the unjust decision, or risk death to rescue her.

Kakunoshin, renowned for his skills with a sword and in the game of go, embodies the samurai code. Falsely accused of a theft, he is forced to become a lowly ronin. Years later, when a case of missing gold pulls him into a new web of intrigue, Kakunoshin uncovers the truth behind his downfall. With the real culprit exposed, the go board flips, and a hellstorm of righteous vengeance follows.

Ogami Itto is hired to kill a tattooed female assassin and battles Retsudo, head of the Yagyu clan, and his son Gunbei.

Ogami Itto is challenged by a quintet of warriors, each armed with one fifth of Ogami's assassin fee and one fifth of the information he needs to complete his assignment.

In 1604, Miyamoto Musashi attacked the Yoshioka family at their dojo and defeated master Seijūrō and his younger brother Denshichirō in two duels. To save their reputation, the Yoshioka family decides to fight back with all 100 family members and hire an additional 300 samurai. Now Musashi sets out to defeat all 400 enemies in his most famous battle.
