The commenter who replied “yes” clearly didn’t understand the question as NO ANIMALS WERE HARMED IN THE MAKING.🙄 The character who kills his whole family also kills the pet cat, but it’s off-screen and also grainy B&W flash book footage. The director, Takashi Shimizu, is a Shinto Buddhist who loves animals.
i think the 'yes' vote is confusing this movie with ju-on: origins (the 2020 tv series). there's no sexual assault in ju-on: the grudge as far as i can recall
