Shogun's Samurai (1978)

Rick, a down-and-out American boxer, is hired to transport a sword to Japan, unaware that the whole thing is a set up in a bitter blood-feud between two brothers, one who follows the traditional path of the samurai and the other a businessman. At the behest of the businessman, Rick undertakes samurai training from the other brother, but joins his cause. He also becomes romantically involved with the samurai's daughter.

A few years after his breakthrough, Sanshiro resumes his path to judo mastery—testing his discipline against an American prizefighter and later facing vengeful karate brothers. As rival schools and public spectacle push him toward violence, he must reconcile strength with restraint and the true spirit of his art.

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.

Ryunosuke, a gifted swordsman plying his trade during the turbulent final days of Shogunate rule, has no moral code and kills without remorse. It’s a way of life that leads to madness.

After years on the road establishing his reputation as Japan's greatest fencer, Takezo returns to Kyoto. Otsu waits for him, yet he has come not for her but to challenge the leader of the region's finest school of fencing. To prove his valor and skill, he walks deliberately into ambushes set up by the school's followers.

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.

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.

His name is Baki Hanma. No one knows where he came from or where he learned his unique fighting style. When it comes to Karate, Baki Hanma is just plain GOOD. He can defeat an opponent with a single blow and he's taking the Karate Championship by storm. In a prestigious match, he defeats competitor after competitor even though he's totally unknown and barely even ranked. But now he's in for the fight of his life and he may have just met his match. Anything goes and his opponent can rip his nerves out -- literally. If he wins, he's the BEST. If he loses... he's DEAD.

Set during Japan's Shogun era, this film looks at life in a samurai compound where young warriors are trained in swordfighting. A number of interpersonal conflicts are brewing in the training room, all centering around a handsome young samurai named Sozaburo Kano. The school's stern master can choose to intervene, or to let Kano decide his own path.

Hellbent on taking over Earthrealm, Kano viciously attacks town after town with the aid of three cold-blooded Black Dragon mercenaries. Those who don’t submit are annihilated but one young man won’t bend the knee to Kano: Kenshi.
