The Nine-Tailed Fox and the Killing Stone: The Legend of Tamamo-no-Mae

A beauty whose story unsettled an empire

At the foot of Mount Nasu in Tochigi Prefecture, an austere volcanic landscape surrounds Sesshōseki, the “Killing Stone.” Sulfurous gases and bare rock give the place an atmosphere that seems made for a ghost story. In local legend, the stone holds the lingering spirit of a white-faced, golden-furred fox with nine tails.

The fox’s most celebrated Japanese incarnation is Tamamo-no-Mae, a woman of astonishing beauty and intelligence at the court of the retired emperor Toba. Her strange radiance, exposure by an onmyōji, and flight to Nasu became material for Noh, kabuki, illustrated books, ukiyo-e, and later popular culture.

Why nine tails? And why does a creature condemned as an enemy of the realm eventually receive Buddhist salvation? The story connects Chinese ideas about auspicious animals with anxieties about imperial power, the rise of warriors, and the possibility of releasing even a dangerous spirit from suffering.

A fox that crossed three kingdoms

The nine-tailed fox did not originate in Japan. It appears in the Chinese Classic of Mountains and Seas, the Shanhaijing, as a remarkable creature of Qingqiu. Across the wider tradition, its meanings range from auspicious signs of flourishing rule and descendants to a destructive being that leads rulers astray.

Medieval Japanese narratives gave this fox an extraordinary journey through India, China, and Japan. In the Indian episode, it appears as Kayō Fujin, the consort of Prince Hanzoku, and encourages horrific acts. In China, it becomes Daji, whose beauty and cruelty bring disaster to the Shang ruler. In Japan, it arrives after crossing the sea and ultimately appears as Tamamo-no-Mae.

These are episodes of a developing literary legend, rather than a record of a single historical animal or woman. Their international scale reveals how medieval storytellers placed Japan within a larger imaginative world shaped by continental culture.

The emperor’s illness and the onmyōji’s discovery

The Japanese tale is set in the late Heian period, when retired emperors exercised considerable authority. Tamamo-no-Mae answers difficult questions without hesitation, masters courtly music, and wins Toba’s affection through both learning and beauty.

During a palace gathering, a violent gust extinguishes every lamp. Yet the darkness does not last: Tamamo-no-Mae’s body shines with an uncanny, moonlike light.

Toba subsequently falls ill, and ordinary treatment cannot restore him. Abe no Yasunari, an onmyōji associated in the legend with the lineage of Abe no Seimei, identifies the supernatural cause.

A purification rite forces Tamamo-no-Mae to reveal her true form. Unable to withstand its sacred power, she becomes a golden fox with nine great tails and escapes toward the plains of Nasu. The scene turns a courtly ideal of brilliant beauty into a disturbing question about appearances and hidden intentions.

Warriors on the plains of Nasu

The court sends an expedition to pursue the fox. Miura no Suke Yoshiaki and Kazusa no Suke Hirotsune lead the warriors in the story.

Fire, dark clouds, and illusions frustrate their efforts. Skill alone is initially insufficient against an enemy that can transform the battlefield itself. The commanders return to training, practising mounted archery through inuōmono, an exercise involving dogs, and prepare for another confrontation.

After a hundred days, the decisive encounter arrives. One arrow strikes the fox’s belly and another its forehead; the warriors close in with their swords.

Read symbolically, this victory marks a shift from the elegance of the Heian court to a world in which the discipline and collective strength of eastern warriors carry greater weight. The tale gives martial training a place within the struggle to restore order.

The Killing Stone and a monk’s compassion

Death does not end the fox’s influence. Its body becomes a stone that releases poisonous vapour, killing creatures and frightening travellers who approach it.

The legend then moves forward roughly two centuries to the monk Gennō Shōgen. He sits before the stone, recites Buddhist teachings, and calls upon the spirit to abandon its attachment and find release. Rather than treating the stone as entirely beyond redemption, he addresses the possibility of Buddha-nature even within it.

Gennō strikes the stone with an iron hammer. It breaks with a great crash, and its fragments scatter across the country. Tamamo-no-Mae’s spirit rises from the opening in white robes, thanks the monk, and finally departs in peace.

The conclusion changes the meaning of the entire story. A dangerous being is not merely defeated: its suffering is brought to an end. The legend’s lasting power lies in that movement from fear and violent struggle toward Buddhist compassion and reconciliation.
