The Pink Tentacle blog has scanned and annotated a few amazing pages from the book, Anatomy of Japanese Folk Monsters by manga artist Shigeru Mizuki. You might recognize Mizuki’s art from his (also-incredible) manga GeGeGe no Kitaro.
The above folk monster is the Kuro-kamikiri (”black hair cutter”) which “is a large, black-haired creature that sneaks up on women in the street at night and surreptitiously cuts off their hair.”
