The Ninja Hunt (1964)

There is a brief rape scene. And in it a man begins sucking on a woman's breast. The nipple is mostly covered by his mouth, but it does slip out for a second. The shy lasts about fifteen seconds, but it is still quite graphic.

A man is slashed while sitting down, blood starts squirting from the wound.

Some mild profanity depending on the translation.

Mild drinking.

Disturbing scene where the main character brutally kills 8 innocent people. This scene is very upsetting.
