There's a lot of female nudity and implied sex throughout.

A woman masturbates in the shower. Her genitals are obscured in usual Japanese fashion.

The scene where a woman tries to kill her lover with a knife is repeated and tweaked constantly. At one point, she wounds his neck IIRC, and there's little blood.

The same man later gets killed. Not a particularly violent scene.

Near the end, we see his corpse, along with his dead wife and child.

A man hangs himself with a noose made out of film reel.
