Kitsune: The Nine-Tailed Fox Spirits of Japanese Folklore
What is a kitsune? Japan's fox spirits explained: why they have nine tails, Inari's messengers, famous legends like Tamamo-no-Mae and Kuzunoha, and kitsune in pop culture.
In this article
A kitsune (狐) is a fox in Japanese folklore with supernatural powers that grow with age and wisdom. The oldest and most powerful foxes have up to nine tails. Kitsune can shape-shift, especially into beautiful women, and create illusions and foxfire. Some are benevolent messengers of the Shinto deity Inari; others are mischievous tricksters or dangerous seducers. Famous legends include the evil nine-tailed fox Tamamo-no-Mae and the loving fox wife Kuzunoha.
Two Kinds of Kitsune
| Type | Description |
|---|---|
| Zenko ("good foxes") | Benevolent, celestial foxes associated with Inari; often white |
| Yako ("field foxes") | Wild, mischievous or malicious foxes that trick or harm humans |
This division appears in later folklore and isn't always strict. Many stories feature foxes that are neither purely good nor evil.
Why Do Kitsune Have Nine Tails?
In East Asian tradition, a fox gains a new tail as it grows older and wiser, sometimes every hundred years. A nine-tailed fox (kyūbi no kitsune) is ancient, wise and extremely powerful. The idea of the nine-tailed fox came to Japan from China, where the huli jing fox spirit appears in texts many centuries older.
Kitsune Powers
- Shape-shifting: into women, men, old people, trees or even a second moon in the sky.
- Illusions: making travelers see palaces, roads or feasts that aren't there.
- Foxfire (kitsunebi): mysterious lights floating in the night.
- Possession (kitsunetsuki): in folk belief, a fox could possess a person, causing strange behavior. Historically, this belief was sometimes used to explain illness.
- Hoshi no tama: some stories give kitsune a glowing pearl or ball that holds part of their power.
Kitsune and Inari
Inari is the Shinto kami (deity) of rice, agriculture, fertility and prosperity. White foxes serve as Inari's messengers. Fox statues, often holding a key, jewel or scroll in their mouths, guard thousands of Inari shrines across Japan. The most famous, Fushimi Inari Taisha in Kyoto, is known for its thousands of red torii gates.
Foxes are said to love aburaage (fried tofu), which is left as an offering at shrines. That's why udon with fried tofu is called kitsune udon.
Famous Kitsune Legends
Tamamo-no-Mae
A beautiful, brilliant courtesan named Tamamo-no-Mae won the favor of Emperor Toba in the 12th century. When the emperor fell mysteriously ill, an onmyōji (court diviner) revealed that she was a nine-tailed fox in disguise. She fled, and warriors hunted and killed her on the plains of Nasu. Her spirit became the Sesshō-seki, the "Killing Stone," said to kill anyone who touched it. In 2022, news spread worldwide when the real Sesshō-seki rock in Nasu was found split in two, likely due to natural weathering.
Kuzunoha, the fox wife
A man named Abe no Yasuna saves a white fox from hunters. Later, he marries a woman named Kuzunoha, and they have a son. One day, the boy sees his mother's fox tail, and she must leave, writing a farewell poem. According to legend, their son grew up to be Abe no Seimei, the most famous onmyōji in Japanese history.
The fox's wedding
When it rains while the sun is shining, Japanese people sometimes say it's a kitsune no yomeiri, "the fox's wedding." Folk belief held that foxes held wedding processions during sunshowers.
Kitsune vs. Other Fox Spirits
