The Slit-Mouthed Woman: The Rumor That Crossed Japan in Six Months

In 1979 a rumour about a masked woman with a mouth slit ear to ear spread from rural Gifu across almost all of Japan in about six months. Children were walked home in groups. Police cars went out on patrol. In Himeji, a real woman was arrested dressed as her. This documentary traces Kuchisake-onna from a farm rumour and a small newspaper column to a national panic, and asks what she really was: cram-school gossip, an "education mama", or a mirror for everyone's fears. Every factual claim is sourced (see below). Legend content is presented as legend.
