Vampire Night(2017)

Vampire Night is a Japanese horror film following a police officer and her younger sister as they seek refuge at a remote ryokan nestled in the mountains, drawn by the hot spring's legendary healing properties. Their retreat takes a sinister turn when they discover the inn harbors a deadly secret: the ryokan serves as a den for vampires. What begins as a peaceful getaway transforms into a fight for survival as the sisters must navigate the supernatural threat lurking within the inn's walls. Blending isolation, atmospheric dread, and creature horror, Vampire Night traps its protagonists in a claustrophobic setting where trust becomes as dangerous as the predators surrounding them.
