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. The futakuchi-onna was once a wife of a miser and rarely able to eat. To counteract this, a second mouth mysteriously appears. 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.
