Jakotsu-Baba (蛇骨婆, Jakotsu-Baba) is a yōkai witch that is said to be a vindictive sort from the northern part of Honshu. The snakes she has with her are red and blue. The blue snake shoots an icy breath that can freeze everything, while the red snake shoot a deadly fire that will reduces the poor victim to ashes.


The Jakotsu Baba originally appeared in Toriyama Sekien’s Konjaku Hyakki Shui (今昔百鬼拾遺; Supplement to the Hundred Demons from the Present and Past). In the illustration she is drawn as an old woman with her body wrapped in snakes.

She is an old woman from in northern Funkan-koku, China. In her right hand she holds a large blue snake, and in her left hand a red one. The people of this country says she is the wife of Jakoemon (Five-Snake Emon), and that she holds vigil over the family tombs. She is sometimes called the Jagoba (the Five-Snake Woman), depending on the dialect of the region.

Little is known about the Jakotsu Baba apart from what Toriyama wrote in his Konjaku Hyakki Shui. It is not known if he invented the character, or if he collected the legend from somewhere or someone. Jakotsu Baba does not appear in any prior collections, either in Japan or China. The other names mentioned by Toriyama—the Snake Family (云蛇塚) and the Old Snake-Bone Woman’s husband Jako Emon—have never been found in any other text, Japanese or Chinese. Nor has the snake-marked tomb been discovered.

It is also interesting that this yōkai lives in China. The setting of the story — Funkan-koku — is mentioned in the Chinese geographic encyclopedia Shan-hai Ching (山海経; Classic of Mountains and Seas). Supposedly, Funkan-koku is a region particularly touched by the supernatural, and renowned for its mediums and fortune tellers. It is possible Toriyama set his story here just to give her a more mysterious air.

Yokai books from the Showa period expanded on the Jakotsu Baba and moved her mysterious grave to Japan. Showa period writers said that Jako Emon was a human, but when he died the sign of a snake was stamped onto his gravestone. To stand guard over his grave, his wife transformed into a yōkai, with a blue snake slithering into her right hand and a red snake into her left. She would attack anyone who came too close to her husband’s grave.

Another unknown is the significance of the color of the two snakes, other than just to be freaky. The only colored snakes in Japanese folklore are white snakes, such as in the story The Tanuki and the White Snake. White snakes are considered sacred, and bring illness and death when accidentally killed.
