Senritsu Kaiki File Kowasugi! File 01: Operation Capture the Slit-Mouthed Woman2012

Horror Vault's take

A scrappy television crew ventures into the streets of Japan to investigate one of the country's most enduring and terrifying urban legends — the Slit-Mouthed Woman. Shot in a raw mockumentary style, the film blurs the line between sensationalist reporting and genuine supernatural dread. Director Koji Shiraishi, who appears on screen, lends the production an uncomfortable authenticity that makes every encounter feel disturbingly plausible.
