I can't actually recommend an Asian horror movie. There is an American movie that's doing really well this year though. It's called Hereditary. It is an indie horror movie that sort of came out of nowhere. It's one of the creepiest movies of recent times. This is the IMDb summary: "After the family matriarch passes away, a grieving family is haunted by tragic and disturbing occurrences, and begin to unravel dark secrets." That's probably enough before you watch it. It's got a rating of 7.6 on there.
