Who Is Futakuchi-onna?

The Futakuchi-onna, or “two-mouthed woman,” is a captivating yet terrifying yokai in Japanese mythology, renowned for her dual mouths that symbolize hidden gluttony and retribution. This supernatural creature typically appears as a beautiful, demure woman who eats sparingly with her front mouth, deceiving those around her.

However, her true horror reveals itself through a second, grotesque mouth on the back of her head, hidden under thick hair, which voraciously consumes food using animated strands as tentacles.

Often born from curses tied to greed, neglect, or accidental wounds, she embodies karmic punishment in folklore, particularly in rural settings like Fukushima and Shimōsa. Her stories warn against selfishness, blending elements of deception, hunger, and moral justice, making her a staple in the yokai lexicon alongside similar afflicted beings.

Etymology

The term Futakuchi-onna derives from ancient Japanese linguistic elements, with “futa” meaning two, “kuchi” signifying mouth, and “onna” denoting woman, creating a straightforward yet evocative name that highlights her most distinctive supernatural trait. Pronounced as foo-tah-koo-chee ohn-nah, this name follows standard Japanese phonetics, emphasizing the duality central to her legend.

In historical texts, such as the Edo-period illustrated book Ehon Hyaku Monogatari authored by Takehara Shunsensai in 1841, the name appears in its kanji form 二口女, solidifying its place in yokai nomenclature. This descriptive naming convention mirrors other yokai like rokurokubi (potter’s wheel neck) or kuchisake-onna (slit-mouthed woman), where physical anomalies define the entity.

Linguistic roots trace back to pre-modern Japanese folklore, influenced by Shinto beliefs in spiritual possession and Buddhist concepts of karma, where physical manifestations reflect inner flaws.

Regional variations exist; in eastern Japan, she might be referenced as a transformed yama-uba (mountain hag), altering her name’s contextual usage without changing the core term. Western tales link her to kumo (magical spiders), suggesting a shape-shifting aspect that enriches the etymology with layers of metamorphosis.

Authors like Toriyama Sekien, in his 1776 work Gazu Hyakki Yagyō, indirectly influenced such names by cataloging yokai, though Futakuchi-onna gained prominence later.

The name’s ties to myths underscore themes of hidden truths and retribution. In oral traditions predating the Edo era, storytellers used it to evoke immediate dread, associating it with food scarcity in feudal Japan. Variations in pronunciation or slight modifications, such as informal rural dialects emphasizing “kuchi” for mouth, reflect Japan’s diverse linguistic landscape.

Connections to related myths include parallels with hone-onna (bone woman), where skeletal transformations echo the skull-splitting horror. By the Meiji era (1868–1912), the name evolved in urban legends, but its core meaning remained intact, ensuring its enduring resonance in cultural narratives.

Scholars note that the etymology encapsulates societal critiques, particularly against parsimony and neglect. In texts like Tōhoku Kaidan no Tabi by Iwai Hiromi in the 20th century, the name is explored in regional contexts, highlighting how it adapts to local folklore.

Without direct synonyms, Futakuchi-onna stands unique, its simplicity aiding memorability in storytelling sessions during the Muromachi period (1336–1573). This linguistic precision, combined with cultural depth, positions the name as a cornerstone in understanding yokai evolution.

What Does the Futakuchi-onna Look Like?

The Futakuchi-onna presents a striking duality in her appearance, initially resembling an elegant, ordinary Japanese woman with delicate features, pale skin, and a serene expression. Her front mouth is small and unassuming, often curved in a modest smile that conceals her deceptive nature.

However, the true horror lies hidden beneath her long, lustrous black hair: a second mouth on the back of her skull, formed by a split in the bone, featuring plump, fat lips that quiver with hunger, rows of sharp, jagged teeth, and a long, slimy tongue that darts out eagerly. This grotesque orifice contrasts sharply with her refined facade, its texture rough and veined, exuding a faint, musty odor reminiscent of decaying food.

In folklore depictions, her hair plays a vital role, animating like writhing serpents or tentacles, with strands thickening to grasp and shovel food into the ravenous maw. Regional variations add nuance; in eastern Japanese tales from Fukushima, her second mouth is portrayed as larger and more vocal, muttering in a raspy, vulgar tone, while western versions from areas like Shimōsa emphasize spider-like qualities, with hair resembling silken webs.

Colors often include pallid flesh tones for her skin, contrasting with the crimson interior of the second mouth, evoking blood and insatiable appetite. Sensory details enhance the terror: the sound of crunching food echoes unnaturally loud, and a slimy residue might linger on stolen provisions.

Artistic representations, such as those in Ehon Hyaku Monogatari from 1841, illustrate her with exaggerated features, the second mouth gaping wide amid parted hair, eyes wild with gluttony. In rural oral traditions, she’s described with textures like leathery lips and brittle teeth, symbolizing decay from moral corruption.

Variations in modern media, like anime adaptations, sometimes add ethereal glows or shadowy auras, but core folklore maintains her humanoid form, blending beauty and monstrosity to underscore themes of hidden deception.

Mythology

The Futakuchi-onna‘s mythology is deeply embedded in Japanese folklore, emerging as a manifestation of karmic retribution and societal warnings against greed and neglect.

Her origins trace to pre-literary oral traditions in rural Japan, likely during the Muromachi period (1336–1573), where stories of cursed women circulated among villagers facing food shortages due to famines or feudal taxes. As a yokai, she belongs to a class of afflicted females, including the rokurokubi whose necks elongate and the kuchisake-onna with her slit mouth, all sharing themes of concealed supernatural transformations triggered by human flaws.

Historical context reveals her legend’s evolution amid Japan’s turbulent eras. During the Sengoku period (1467–1603), marked by wars and instability, tales of Futakuchi-onna may have symbolized the hidden costs of survival, where hoarding resources led to familial discord. The Edo period (1603–1868) saw her formalized in literature, influenced by peaceful urbanization and a boom in yokai catalogs.

Takehara Shunsensai’s Ehon Hyaku Monogatari in 1841 depicted her vividly, drawing from earlier works like Toriyama Sekien’s Gazu Hyakki Yagyō (1776), which popularized yokai imagery. These texts blended Shinto animism—viewing spirits in everyday objects—with Buddhist karma, where deeds like starving others rebound as physical curses.

Cultural significance lies in her role as a moral arbiter. In agrarian societies plagued by crop failures, such as the Tenmei famine (1782–1788), her insatiable hunger mirrored real fears of starvation, critiquing miserly behaviors that exacerbated community suffering.

Connections to other beings enrich her lore: in eastern regions, she’s a shape-shifted yama-uba, a mountain hag from ancient myths tied to isolation and cannibalism; in western Japan, links to kumo spiders evoke web-like deception and entrapment. Parallels with hone-onna, a seductive skeleton, highlight themes of retribution through bodily horror.

Her evolution continued into the Meiji era (1868–1912), where Western influences diluted some traditions, but rural tales persisted, adapting to industrialization’s social changes.

Post-World War II, amid reconstruction and food rationing, her stories resurfaced in manga like Shigeru Mizuki’s GeGeGe no Kitarō (1959 onward), portraying her as a tragic figure rather than purely malevolent. This shift reflects Japan’s modernization, where yokai symbolize lingering cultural anxieties.

Influences from historical events, like the Black Death-inspired plagues in Europe paralleling Japan’s epidemics, may have shaped her curse motifs, emphasizing neglect’s consequences. Pre-literary beliefs in ancestral spirits possessing the living add depth, suggesting the second mouth as a vessel for wronged souls. Figures like folklorist Yanagita Kunio (1875–1962) documented her in works like Tōno Monogatari (1910), preserving regional nuances.

Overall, the Futakuchi-onna‘s mythology weaves a narrative of ethical balance, evolving from ancient warnings to modern symbols of repressed desires, her presence enduring in Japan’s collective psyche.

Legends

The Miser’s Frugal Bride in Fukushima

In a secluded village nestled in the misty hills of Fukushima during the early Edo period around 1650, there lived a notoriously stingy man named Hiroshi, known throughout the region for his unyielding parsimony. Hiroshi, a rice farmer who hoarded every grain, refused to marry for fear of the added expense of feeding another mouth.

One fateful autumn day, while trading at the local market, he encountered a graceful woman named Aiko, whose beauty captivated the villagers. Aiko claimed to eat nothing, surviving on mere sips of water and the occasional wild berry, which delighted Hiroshi as it aligned perfectly with his frugal ways. He proposed marriage immediately, and they wed in a simple ceremony under the harvest moon.

As months passed, Hiroshi noticed his carefully stored rice barrels depleting at an alarming rate, despite Aiko’s apparent abstinence from meals. Puzzled and suspicious, he devised a plan one crisp morning in 1651: pretending to head to the fields for a long day’s work, he instead concealed himself in the rafters of their modest thatched home. From his vantage point, he watched in growing horror as Aiko’s long, ebony hair began to stir unnaturally.

The strands parted like curtains, revealing a gaping second mouth on the back of her skull—plump lips curling back over jagged teeth, a slimy tongue lashing out. Her hair, now animated like living tentacles, snaked into the rice storage, scooping handfuls of grains and shoving them into the ravenous maw, which cooed vulgarly in satisfaction, its raspy voice echoing threats of endless hunger.

Terrified, Hiroshi fled the house but later confronted Aiko, demanding a divorce. Enraged, she revealed her true nature as a shape-shifted yama-uba from the eastern mountains, cursing him for his greed. She trapped him in an old wooden bathtub, hoisting it onto her back with supernatural strength, and carried him toward the foreboding peaks where she intended to devour him whole.

Midway through the dense forest, Hiroshi wriggled free during a moment of distraction and plunged into a nearby lily marsh, its overpowering floral scent masking his presence. Aiko searched frantically but could not locate him, her second mouth shrieking in frustration. Hiroshi remained hidden until dawn, eventually returning to the village to warn others of the perils of excessive thrift.

This tale, passed down through generations in Fukushima, underscores the ironic twist where greed invites greater loss, blending horror with a poignant lesson on balance and generosity.

The Stepmother’s Cruel Neglect in Shimōsa

Amid the fertile plains of Shimōsa province in the late 1700s, a widower named Kenji, a humble woodcutter, remarried after losing his first wife to illness. His new bride, Yuki, brought her own daughter into the household, joining Kenji’s young girl, Haru. Yuki, driven by favoritism and scarcity during a harsh famine in 1783, lavished food upon her biological child while rationing Haru’s portions to mere scraps.

Day after day, Haru grew weaker, her pleas for sustenance ignored as Yuki hoarded rice and vegetables for her own kin. After forty-nine agonizing days—a number significant in Buddhist mourning rituals—Haru succumbed to starvation, her spirit lingering in silent accusation.

On the eve of the forty-ninth day, Yuki awoke to a throbbing pain splitting the back of her head. As she clutched her skull in agony, the flesh parted, forming a second mouth complete with swollen lips, gnashing teeth, and a probing tongue.

This new orifice, aching with insatiable hunger, began to demand food in Haru’s faint, ethereal voice, recounting the torments of neglect: “You let me starve while your child feasted; now feel my endless pain.” Yuki’s hair came alive, twisting into tendrils that raided the kitchen, forcing rice and fish into the maw, which shrieked if denied, inflicting excruciating headaches upon her.

Kenji, witnessing this transformation one stormy night, confronted Yuki, who confessed her wickedness. The second mouth, embodying Haru’s vengeful spirit, tormented her relentlessly, mirroring the hunger pangs she had inflicted. In desperation, Yuki fled into the wilderness, her dual mouths clashing in eternal conflict.

Villagers in Shimōsa whispered of this event for years, attributing it to karmic justice influenced by local Shinto shrines dedicated to ancestral spirits. This narrative, distinct in its focus on familial betrayal and spiritual possession, serves as a stark reminder of the consequences of partiality and cruelty within the home.

The Accidental Axe Wound and Its Grisly Aftermath

In a foggy woodland hamlet of Shimōsa around 1720, a hardworking lumberjack named Taro lived with his second wife, Miko, and his daughter from a previous marriage, named Sora. Miko, resentful of Sora, favored her own offspring, skimping on Sora’s meals during lean times following a poor harvest.

One crisp winter day, as Taro swung his axe to fell a sturdy oak, Miko approached from behind to argue about household expenses. In a tragic mishap, the axe glanced off the tree and struck the back of Miko’s head, leaving a deep gash that refused to heal despite herbal poultices and prayers at the village temple.

Over the ensuing forty-nine days, the wound festered unnaturally, swelling and morphing into a functional second mouth—lips emerging from the scar tissue, teeth pushing through like sprouting buds, and a tongue unfurling with a wet slap.

This mouth, born from the accidental injury intertwined with Miko’s underlying malice, began to voraciously crave sustenance, using Miko’s hair as grasping appendages to pilfer from the larder. It spoke in Sora’s voice, accusing Miko of deliberate starvation: “Your jealousy wounded me more than any blade; now I feed through you.”

Taro, horrified upon discovering the mutation while Miko slept, pieced together the curse’s origin—a blend of the axe wound and karmic backlash from Sora’s mistreatment, who had weakened but survived in this variant. Miko’s attempts to conceal the mouth failed as it grew bolder, muttering curses and demanding feasts that depleted their stores.

Eventually, Taro performed a ritual at a local Inari shrine, offering rice to appease the spirit, which temporarily quieted the mouth. Miko, reformed by the ordeal, began treating Sora equitably, and the mouth receded into a scar. This story, unique in its accidental catalyst and path to redemption, highlights forgiveness and the interplay of fate and morality in Japanese rural lore.

The Spider’s Deceptive Web in Western Japan

Far from the eastern hills, in a coastal village of western Japan during the mid-1600s, whispers spread of a beguiling woman named Izumi who arrived amid a typhoon in 1645. Izumi, with her silken black hair and enigmatic smile, quickly wed a prosperous fisherman named Jiro, drawn to her promise of minimal needs.

Yet, as storms ravaged crops, Jiro’s fish hauls vanished mysteriously, despite Izumi’s dainty eating habits. Suspecting theft, Jiro hid one moonless night and beheld a nightmarish sight: Izumi’s hair weaving like spider threads, parting to expose a second mouth, its lips glistening like dew on a web, teeth chattering as it devoured his catches.

Revealed as a shape-shifted kumo—a magical spider from ancient forests—Izumi’s form twisted, her mouth hissing arachnid-like threats. Jiro, recalling local legends, fled to a sacred grove where he burned incense infused with potent herbs, the smoke repelling her pursuit. Izumi retreated to the shadows, her curse a punishment for Jiro’s earlier greed in overfishing sacred waters.

This western variation emphasizes shape-shifting and natural retribution, differing from eastern tales by incorporating spider motifs symbolic of entrapment and fate’s intricate webs.

The Starved Child’s Vengeful Possession

In a mountainous enclave of eastern Japan circa 1800, a widow named Rei remarried a merchant, bringing her stepson, Kaito, into a household strained by the Kansei famine (1792–1793).

Rei, prioritizing her own children, denied Kaito adequate nourishment, leading to his tragic death after weeks of deprivation. Precisely forty-nine days later, during a ritual mourning, Rei’s head throbbed violently, splitting to birth a second mouth that echoed Kaito’s cries: “Hunger you imposed, now eternal in me.”

Her hair, now possessed tendrils, ravaged the pantry, the mouth’s pain transferring to Rei if unfed. The merchant, seeking aid from a wandering monk, underwent a purification rite involving chants and offerings, which exorcised the spirit.

Rei, haunted by guilt, dedicated her life to charity. This legend, centered on possession and redemption, varies in its spiritual resolution, reinforcing Buddhist themes of atonement.

The Futakuchi-onna aligns closely with Japanese yokai like rokurokubi and kuchisake-onna through shared curses transforming women, emphasizing deception and moral failings, yet differs in her focus on gluttony rather than physical extension or vanity. Her hair tentacles echo the Penanggalan‘s entrails, both hidden horrors feeding nocturnally, but she lacks the detachment aspect.

Compared to Western entities like Medusa, her curse is karmic and internal, not divine punishment with petrification powers. Similarities with yama-uba and nogitsune lie in shape-shifting and retribution, but her weaknesses—scents and generosity—highlight Japanese folklore’s preference for ethical resolutions over violent confrontations seen in Greek myths.

Powers and Abilities

The Futakuchi-onna wields a array of supernatural powers that render her both subtle and formidable in Japanese folklore. Her most prominent ability is the autonomous operation of her second mouth, which functions independently, devouring enormous quantities of food with an unquenchable appetite.

This mouth not only eats but vocalizes, often in a raspy, threatening tone, inflicting psychological dread by echoing victims’ past wrongs or muttering curses, as depicted in stepmother tales where it speaks as the starved child.

Hair manipulation stands as another key strength, with strands animating into tentacle-like appendages capable of precise, serpentine movements to seize and feed provisions into the hidden maw.

In eastern variants, this extends to shape-shifting, allowing her to pose as a yama-uba or ordinary woman, blending seamlessly into human society until revealed. Western stories enhance this with spider-like qualities, her hair weaving illusory webs to entrap prey or obscure her presence.

Her curse inducement ties to karmic forces, transforming neglect or greed into physical afflictions that perpetuate suffering. Examples include causing endless hunger pangs in hosts or depleting resources to mirror the original sin.

While not overtly aggressive, her abilities foster isolation and fear, making her a passive yet destructive force in households.

Can You Defeat Futakuchi-onna?

Confronting a Futakuchi-onna requires understanding her curse’s roots in greed and neglect, with traditional Japanese folklore offering methods centered on moral rectification rather than direct violence. One primary approach involves strong scents; in the miser’s tale from Fukushima, hiding in a lily marsh overwhelmed her senses, preventing pursuit.

Herbal rituals expand this: burning incense from sacred woods like cedar or sandalwood, infused with potent herbs such as mugwort or ginger, creates a protective barrier, as these aromas disrupt her second mouth’s acute olfactory detection.

Regional variations provide diverse tools. In eastern Japan, where she’s linked to yama-uba, Shinto purification rites at local shrines—offering rice and sake while chanting invocations to ancestral spirits—can appease the curse, encouraging the yokai to depart.

Western tales, associating her with kumo spiders, suggest using iron implements, like nails or blades, to pin her hair tentacles, symbolizing the breaking of web-like deceptions. Acts of generosity counter her essence; providing abundant food willingly may satiate the mouth, diminishing its power, akin to how rokurokubi weaken through exposure.

Comparisons to similar creatures illuminate strategies. Like the kuchisake-onna, distraction works—offering confusing abundance or moral confessions mirrors her evasive tactics with candy. For hone-onna, talismans inscribed with Buddhist sutras ward off possession, applicable here by wearing amulets of jade or reciting the Heart Sutra to expel vengeful spirits. In severe cases, enlisting a monk for exorcism, involving fasting and meditation, addresses the karmic debt, much like defeating nogitsune through spiritual cleansing.

Preventive measures include communal harmony: sharing meals equitably avoids invoking the curse, reflecting folklore’s emphasis on balance. Tools like mirrors to reveal hidden truths or salted barriers, drawn from general yokai wards, add layers. Ultimately, defeating Futakuchi-onna transcends physical means, demanding introspection and ethical reform to dissolve her hold.

Conclusion

The Futakuchi-onna encapsulates the intricate blend of horror and morality in Japanese mythology, her dual mouths serving as eternal reminders of the dangers lurking in unchecked human vices.

Through her legends, we glimpse the cultural fabric of feudal Japan, where scarcity bred tales that championed equity and warned against deception. Her enduring legacy, from ancient oral stories to contemporary adaptations, affirms her role as a timeless supernatural entity.

As societies evolve, the Futakuchi-onna adapts, symbolizing modern issues like hidden addictions or societal neglect, her ravenous hunger a metaphor for insatiable desires. Exploring her lore invites deeper appreciation for yokai’s philosophical depths, bridging past and present in a dialogue on ethics and the human condition.
