Kurobōzu (黒坊主 or くろぼうず, Kurobōzu) is a yokai from the folklore in the Meiji era. He looks like a black monk, but blurry to the human eye. Kurobouzu would come into a woman's room when she is asleep and sucks her breath or licking her mouth.
As with many yokai, the “monk” part does not have any particular religious meaning. Many yokai have this as part of their name, which could just as easily mean “stranger.” Kurobozu is also used as an alternate name for other yokai like the umibōzu and takabozu.
Aside from the bald head, the Kurobozu is depicted as vaguely human-like, although shrouded in a pitch black monk’s robe. It is like a living shadow. Its head is featureless, except for the vague appearance of two eyes that sometimes reflect the light. The lack of face leads some to consider the Kurobozu to be a type of Nopperabo. Based on the two types of Kurobuzo stories, the images are often merged into a bear-like monster wrapped in a monk’s robes.
During the Meiji period (1868 – 1912), sensationalist newspapers ran illustrated stories of crime, yokai, and other supernatural happenings. These stories were often very short; a bit of text accompanied by an eye-catching illustration. This is how the Kurobozu entered the yokai pantheon, in the 663rd issue of the Yubinhouchi Shinbun (郵便報知新聞; Postal Intelligence Newspaper). A family living in the Kimata area of Tokyo reported a strange disturbance. Each night while they were sleeping a strange presence would appear in their bedrooms. The presence hovered over the wife, leaning close to her. It slobbered over her face, and sucked her sleeping breath from her mouth. In the morning, the wife’s breath and face would stink of rotting flesh. She fell ill. Unable to tolerate it any longer, the wife went to stay at a relative’s house. The mysterious Kurobozu did not follow her there, and she was able to recover her health. After some time, she returned home and has reported no further disturbance. The Kurobozu has disappeared.
There is another legend of a creature called a Kurobozu that comes from the Edo period, and is recorded as a local legend of Kumano in the kidan-shu Sankawa Kidan (三州奇談; Romantic Tales of Three Rivers). The story tells of a hunter who encounters a large, black monster out in the woods, looking something like a black bear. When the hunter shot it with his rifle, the monster grew in size until it was several meters tall. Terrified the hunter fired again, and the monster fled, moving over the difficult terrain at an incredible pace, almost as if it was flying.
