K is for Kumakatok - The "Kumakatok" (Door Knockers) are a group of three robed figures believed by many to knock on doors in the middle of the night, bringing bad omens. They allegedly look like humans but wear hoods which obscure their faces to some extent. One resembles a young female while the other two look like old people. The visits are supposedly more frequent after a disease outbreak. Reported sightings of the Kumakatok have decreased significantly since World War II.
