Kuroneko (1968)

"Beware what lurks in the bamboo forest craving the blood of samurai!"

In the Sengoku period, a woman and her daughter are raped and murdered by soldiers during a time of civil war. Afterwards, a series of samurai returning from the war through that area are found mysteriously dead with their throats torn out. The governor calls in a wild and fierce young hero to quell what is evidently an Onryō ghost.
