An image of a futakuchi-onna from the Ehon Hyaku Monogatari

A futakuchi-onna (二口女, lit. "two-mouthed woman") is a type of yōkai or Japanese monster. They are characterized by their two mouths – a normal one located on her face and second one on the back of the head beneath the hair. There, the woman's skull splits apart, forming lips, teeth and a tongue, creating an entirely functional second mouth.

In Japanese mythology and folklore, the futakuchi-onna belongs to the same class of stories as the rokurokubi, kuchisake-onna and the yama-uba, women afflicted with a curse or supernatural disease that transforms them into yōkai. The supernatural nature of the women in these stories is usually concealed until the last minute, when the true self is revealed.

Origins of the second mouth[edit]

The origin of a futakuchi-onna's second mouth is often linked to how little a woman eats.[1] In many stories, the soon-to-be futakuchi-onna is a wife of a miser and rarely eats. To counteract this, a second mouth mysteriously appears on the back of the woman's head. The second mouth often mumbles spiteful and threatening things to the woman and demands food. If it is not fed, it can screech obscenely and cause the woman tremendous pain. Eventually, the woman's hair begins to move like a pair of serpents, allowing the mouth to help itself to the woman's meals. While no food passes through her normal lips, the mouth in the back of her head consumes twice what the other one would. In another story, the extra mouth is formed when a stingy woman is accidentally hit in the head by her husband's axe while he is chopping wood, and the wound never heals. Other stories have the woman as a mother who lets her stepchild die of starvation while keeping her own offspring well fed; presumably, the spirit of the neglected child lodges itself in the stepmother's or the surviving daughter's body to exact revenge.

Prototypical story[edit]

This is the most famous and prototypical story of a futakuchi-onna:

In a small village there lived a stingy miser who, because he could not bear the expense of paying for food for a wife, lived entirely by himself.

One day he met a woman who did not eat anything, whom he immediately took for his wife. Because she never ate a thing, and was still a hard worker, the old miser was extraordinarily thrilled with her, but on the other hand he began to wonder why his stores of rice were steadily decreasing.

One day the man pretended to leave for work, but instead stayed behind to spy on his new wife. To his horror, he saw his wife’s hair part on the back of her head, her skull split wide revealing a gaping mouth. She unbound her hair, which reached out like tentacles to grasp the rice and shovel it into the hungry mouth.

In popular culture[edit]

  • In the manga Gantz a creature that has the characteristics of both the Futakuhi-onna and the Rokurokubi (i.e. second mouth on the back of the head and the ability to elongate the neck) is seen in later chapters of the series albeit briefly. It is not stated if this is another variation of the creature or a way to feature both at the same time.
  • The long running anime series GeGeGe No Kitaro often features Futakuchi-onna as an antagonist to Kitaro. Her skin is a pale white with raven black hair which can form snake-like ropes that stretch out and snare victims, often to pull them towards her horrifically large mouth on the back of her head which has sharp teeth. She is also known to work with other Yōkai antagonists Kamaitachi and Tantanbō.
