Similar to the sexual content in the film, most of the violence is implied. Gore is almost non-existent.
The setting of the movie is during the chaos of a war, so several scenes of samurai raiding villages can be seen. They kick down and push over peasants, but no blood or gore can be seen.
A wounded man is found drifting in a boat on a lake. A head wound is visible, and he dies shortly after he is found.
A man is beheaded. The camera pans in such a way that the actually beheading takes place behind a rock, and as it pans back, the man covers up the missing head before anything is actually seen.
The head is later presented to an army official. It is unwrapped from a cloth in such a way that no blood or gore is actually seen.
A man is stabbed with a spear, though it is clear to the viewer that the spear doesn't penetrate the armor and no blood is seen. The man dies of his wounds.
