1968 film directed by Keiichi Ozawa

Goro (Tetsuya Watari) wants to put his dark past behind. He heads to Hirosaki City to offer his condolences to Yumeko and to reunite with Yukiko (Chieko Matsubara), but finds that Yumeko is fatally ill. Although Yukiko was taking care of her, she is pressed for money. Goro wants to help and knows that there is only one way to come up with fast money.

On a cold winter day, Goro Fujikawa (Tetsuya Watari) and Masahiko murder the mob boss of Meishin-Kai. The deed costs them time in prison, but Goro had no shred of regret. When Goro is released 2 years later, Masahiko is dying in prison hospital and entrusts his last wish; "find my sister and take care of her." Goro leaves as a free man with a mission, but soon finds that he might have been better off in jail.

Goro had grown up in the yakuza world. As an active member of the Mizuhara family crime syndicate, he expressed his loyalty by always putting himself in the forefront of every battle. Violence never bothered him. However, after being sentenced to three years in prison for stabbing a rival gang’s hit man, he becomes disenchanted with the Yakuza life style. Goro is determined to start anew, but karma catches up. His two closest friends are murdered by his ex-boss. He is left with two options: to kill or be killed.

As the Shogun lays dying, seventeen Iga clan ninja are sent to infiltrate the impenetrable fortress where his youngest son is preparing to storm Edo Castle and name himself Shogun by force of arms. They are to either steal the documents that will eventually give him lawful claim to rulership, or they are to assassinate him. But even before they reach the castle walls, they find their every move countered by a ruthless ninja hunter in the employ of the would-be usurper (Konoe), who not only knows their every tactic but knows the exact make-up of their team thanks to his own spies within Edo Castle. As the Iga Ninja fall one by one, the mission's success or complete failure--where failure will result in a bloody war of succession--comes to hinge on a single young and inexperienced ninja (Kotaro).

A young yakuza hitman named Goro does a job and needs to hideout away from Tokyo for a while. He hangs out with loose women and hard men and always manages to stay one step ahead of the law. In his exile, he comes under suspicion for a murder and meets the girlfriend of the murdered man. They develop a strange bond while unbeknown to Goro, another hitman is after him for the job he did in Tokyo.

1978 film by Hideo Gosha

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.

Kon Ichikawa's retelling of the classic true story of Samurai honor. When a young clan lord is forced to commit seppuku (ritual suicide), his loyal followers (now Ronin, masterless Samurai) dedicate their lives to avenging his death.

A cynical samurai is left as the sole survivor to fulfill a plot to assassinate the puppet of a villain intent on usurping the shogunate in the 17th century. A Shogunate Elder connives to rule Japan by making his puppet, the Shogun's brother Tsunashige, the next Shogun. The best strategist in Japan, Yamaga, leads a plot to stop the Elder, but his cabal is betrayed and most of the conspirators are captured and tortured.
