This version of The Pot Worth a Million Ryo (Tange Sazen: Ken Fu! Hyakumanryu no tsubo, 1982) stars Tatsuya Nakadai in the central role. He obviously studied Denjiro Okochi's body movements & adopted the hopping gait in the fight sequences, but Nakadai adds other body posture traits that make the character visually his own.
One problem with so many Sazen films is it's pretty difficult to hide the fact that the actor doesn't actually have only one arm. For Nakadai, too, when he's in his most intense action scenes, you'll catch glimpses of his supposedly missing arm's elbow poking at his kimono. But in the main, he has found postures that make him look authentically rawboned & one-armed.
He tends to keep the "armless" shoulder higher than the other giving himself a sharp angular look on that side, & rests his drawn swordblade on the armless shoulder between slashes & cuts (Denjiro tended to rest his sword on his right shoulder so as not to draw too much attention to the fact that his left arm was sometimes detectible).
