The thing where you sound like a slightly different person on a work call has a name, and people have been measuring it since the 1950s.
Sociolinguists call it style-shifting, or code-switching when it crosses languages or dialects. The model that stuck is Allan Bell's, published in 1984 in Language in Society as "Language Style as Audience Design," and its claim is that the main driver of how you talk is the audience in front of you, ahead of your mood and ahead of your subject.
His evidence is the part I can't put down. New Zealand public radio ran two stations, YA and ZB, out of the same suite of studios. YA was the national network, with the higher-status audience. ZB was local community radio. The same newsreaders read the bulletins for both, on the same day, in the same building. Bell measured one small feature of their speech, the way they voiced a t between vowels, and found the same individual announcers shifting about twenty percent between the two stations.
Same person, same hour, no memo and no coaching. The audience changed and the mouth followed.
(Mine does this too. The voice I answer an unknown number with is roughly four percent British, and I have never been to Britain.)
Nobody in that study was lying.
So. Kitsune.
The fox is not the god, and almost everybody gets this backwards
狐 is the ordinary Japanese word for fox, not a monster name and not a term of art. The animal is out there right now doing fox things in the actual countryside, and the word for it is the same word that carries twelve hundred years of religious and literary freight.
In folklore the kitsune is a fox that has acquired power, most famously the power to change shape, and it belongs to the broad category of yōkai. That's the folklore side.
The religious side is separate. It also gets mangled constantly, including by people who mean well, and including by me before I looked it up. So, slowly.
Inari Ōkami is a kami. Inari is not a fox.
Inari Ōkami is one of the major deities of Shinto, associated with rice, agriculture, sake, tea, foxes, industry, and general prosperity, and the foxes are Inari's messengers. Attendants. The ones who take a person's request up the chain and put it in front of the kami. Typically white, which is where you get byakko as a term for them, and white is a good sign when you see one.
The line has gotten blurry over the centuries and there are contexts where Inari is depicted as a fox, and I'm in no position to tell a thousand years of practice it's doing itself wrong. What I'll tell you is that the standard, well-sourced version has the fox as messenger, and that "the Japanese fox god" is a phrase you should treat as a red flag about wherever you just read it.
This is a living religion, by the way, and not a small one. Roughly a third of all Shinto shrines in Japan are Inari shrines. The figure usually cited is over 30,000. Which is a lot. Counts that include the tiny ones tucked beside a rice field or bolted to the roof of an office building run higher than that. The head shrine is Fushimi Inari-taisha, on Mount Inari in Kyoto, founded in 711 CE, though some scholars argue for a start in the late fifth century.
Fushimi Inari is the one you've seen without knowing you've seen it: the tunnels of vermilion torii gates going up the mountain, thousands of them, each one donated by a person or a business with the donor's name painted on the back. The famous stretch is called the Senbon Torii, "thousand torii," and senbon here means "loads," the way you'd say a million. Estimates for the whole mountain run around ten thousand. Nobody can give you a fixed number because gates get taken down, repaired, and replaced continuously, which I find much more charming than a fixed number would have been.
(The fox statues at Inari shrines usually come in pairs flanking the approach, and a great many of them are wearing small red bibs, which are put there by people, and which get swapped out when they weather, and if you have ever half-wondered whether a religion this old is being actively maintained or is just sitting there being old, the answer is that somebody drove out to a shrine on a Tuesday holding a bib.)
Inari's own gender isn't settled and never has been. Male in some traditions, female in others, sometimes understood as a collective of three to five kami. The disagreement is the record, and it isn't a hole in it.
Also: the offerings at Inari shrines include aburaage, deep-fried tofu pouches, on the understanding that this is what foxes like. That's why the noodle dish with the sweet fried tofu on top is called kitsune udon and why the stuffed rice pouches are called inari-zushi. You have possibly eaten a religious offering with a fork.
Good foxes, field foxes, and the people who drew the line
The folk taxonomy splits roughly into two, and the split is real but it isn't ancient and pure.
Zenko (善狐), "good foxes," are the ones aligned with Inari. Helpful, protective, usually white, generally on your side. Yako (野狐), "field foxes," also called nogitsune, are the freelancers. Mischief, deception, sometimes real harm. A third category, ninko (人狐), "man-fox," is tied specifically to possession and gets treated as the worst of the lot. Nope.
My verdict: useful, but it's a filing system and not a natural fact. The scholar Nakamura Teiri has argued that it was religious practitioners and the educated class who made the good-fox versus bad-fox division commonplace. The tidy version came from above. Popular belief was messier, and more nervous about foxes across the board.
A second contested point, which I'd rather flag than skip: some scholars have suggested the fox was venerated in its own right as a rice deity in earlier periods, and that the messenger role got layered on afterward. Argued, not settled. I'm not picking a winner from where I'm sitting.
Counting the tails, and the jewel she carries
More tails means older and stronger. That part is consistent.
The rest isn't.
The neat version you've absorbed from games and anime, one tail per century until she hits nine at nine hundred or a thousand years, is a tidy-up. Not invented out of nothing. Some folktales do say a fox grows an extra tail after living a hundred years. But the older material isn't running a uniform arithmetic, and the counts that actually recur are one, five, seven, and nine rather than a smooth ladder. The honest sentence: the progression is real, the calculator is modern.
The nine-tailed fox, kyūbi no kitsune (九尾の狐), sits at the top of it, and she's an import. She comes into Japan out of Chinese tradition and arrives already carrying a reputation for the kind of court-destroying beauty we'll get to in a minute.
Then there's the hoshi no tama, the star ball. A small white sphere the fox keeps, sometimes in her mouth, sometimes at the tip of a tail, and it's tied to her ability to change shape and to use her power at all. In statuary and temple art the jewel a fox holds is generally read as the Buddhist wish-granting jewel, which is the sort of overlap you get constantly once Buddhism and Shinto have spent a thousand years in the same buildings.
One note about the shapeshifting itself, because the Western reflex is to read it as a lie-detector problem. In the tales, a fox in the form of a woman marries a man, keeps the house, has children, and is a genuinely good wife. Then she's discovered. The grief in the story has nothing to do with her having faked anything. She has to leave, is the problem, and the household she ran for twelve years is finished by lunchtime.
Tamamo-no-Mae, and the rock that broke in March 2022
The most famous kitsune in Japan is a courtesan who wasn't one.
The story, as it comes down through Muromachi-period otogizōshi prose tales and gets elaborated for centuries afterward: a woman of extraordinary beauty and learning called Tamamo-no-Mae arrives at court and becomes the emperor's favorite. The emperor sickens. Nobody can find a cause. The onmyōji Abe no Yasuchika is called in to diagnose it and identifies her as a nine-tailed fox. Exposed, she flees to the plain of Nasu, and the warriors Kazusa-no-suke and Miura-no-suke are sent to hunt her down.
Contested, and worth getting right: the standard texts put her at the court of Emperor Konoe, who reigned 1142 to 1155. Plenty of popular retellings, including news coverage in 2022, put her with Emperor Toba, who reigned 1107 to 1123 and was Konoe's father and later cloistered emperor. Both are in circulation. Konoe is what the otogizōshi tradition supports.
Later layers push her backward in time and identify her with Daji, the consort blamed for the fall of King Zhou's Shang dynasty in China. So the same fox is retroactively made responsible for wrecking two courts in two countries. That's an argument being made in narrative form, about foreign beauty and imperial weakness, and it isn't subtle.
After she's killed, her spirit goes into a stone at Nasu, and the stone starts killing things that come near it. It's called the Sesshō-seki (殺生石), the killing stone. The version where her spirit enters the rock shows up in a 1653 addendum to the Tamamo no sōshi. A Buddhist monk, Gennō Shinshō, eventually breaks the stone and releases the now-repentant spirit.
Now the part I like. Nasu is volcanic and full of sulfurous hot springs, and volcanic gas really does pool in the low spots there and really does kill small animals that wander in. "Sesshō-seki" gets used in Japan as a general name for rocks in places where toxic volcanic gas comes up. So it kills. The danger was already sitting there and all the legend had to do was account for it, which is an unusually clean example of folklore doing its actual job.
And then, on March 5, 2022, the Sesshō-seki at Nasu was found split into two pieces.
The internet had an excellent week. Officials said a crack had been in the stone for years and that rain getting in and freezing was the likely cause, which is the boring correct answer and also, I'd like to point out, the same answer as "the seal weakened over time." On March 26, 2022, local officials had priests hold a ceremony at the site to settle the spirit, with prayers, offerings, and the waving of a haraegushi over the broken rock. Right call. A thing that has been a landmark and a story for six hundred years came apart, and somebody showed up and said words over it.
When a village decided the fox was inside somebody
Don't skim this one. It's where the charm runs out.
Kitsunetsuki (狐憑き) means the state of being possessed by a fox. It's attested from the Heian period. There's an early instance in the ninth-century Nihon ryōiki, and it stayed a live diagnosis for well over a thousand years. The person afflicted was very often a young woman. Reported signs included restlessness, listlessness, avoiding eye contact, a sudden craving for rice or sweet red beans, and a face that people said had gone fox-like.
Physicians started arguing it was an illness a long time before the argument won. An 1818 text, Jinko benwaku dan, laid it out as disease. It didn't take. In the late nineteenth century the physician Shimamura Shunichi observed that plain feverish illnesses were regularly getting filed as kitsunetsuki. In 1885 a German physician working in Japan coined "alopecanthropy" for it, which is a word that tells you more about 1885 than about foxes.
The genuinely ugly part is kitsune-mochi, the fox-owning families. Beginning around the Kyōhō era in the 1710s, in the Izumo region, which is modern Shimane Prefecture, a belief took hold that certain households kept foxes, and that those foxes did the possessing on the family's behalf. This was hereditary. It attached to a family line. Those families got shunned, and people would not marry into them. What that gave a village was a working system for deciding which of your neighbors was untouchable, and it was still turning up in regional studies conducted as late as around 1960.
Ugh.
The modern academic treatment is careful. In 1991, Culture, Medicine and Psychiatry ran two papers in the same volume on this: Eguchi's study of two cases of kitsune-tsuki in a mountain village in western Japan, examined from both psychiatric and ethnographic angles, and Etsuko's "The interpretation of fox possession: illness as metaphor." The framing across that literature is that a psychiatric diagnosis translates part of the indigenous illness and does not simply replace it.
My verdict, for whatever it's worth on a website: the possession belief is documented, the suffering was real, the medical reframing was correct and arrived late, and the family stigma was a straightforward engine of cruelty that the folklore made respectable.
Her cousins in China and Korea are not her
Three fox traditions. Related, not interchangeable, and the internet mashes them constantly.
The Chinese huli jing (狐狸精) is the older one, and the source of the nine-tailed form that came into Japan. Chinese fox-spirit literature is enormous. It runs the whole moral range, seductress to scholar's devoted companion to local deity with a shrine of her own.
The Korean kumiho (구미호) is the nine-tailed fox in a much less forgiving setting. The scholarly point I'd hold onto is a negative one. The fox in Korea does not appear to have gotten the Buddhist integration it got in Japan, and Confucian ideology through the Joseon period pushed it further out. So the kumiho comes down to us deceptive, dangerous, and tragic, with the sympathetic version arriving mostly in modern retellings. There's a fox bead there too. It's the yeouiju, taken from the fox's mouth, and it grants knowledge or power to whoever ends up with it. The word also gets used as an insult for women, which is its own piece of information.
Japan is the outlier of the three, and specifically because of Inari, since a fox with an official job inside a national religion is going to age differently than a fox with no employment at all, though even in Japan the yako never got the benefit of it.
What a shapeshifter is actually for
Every tradition that has one keeps it for a reason. The reason is hardly ever the disguise.
The kitsune wife stories don't end when the deception is exposed, they end when she leaves, and the leaving is what everybody in the story cries about. Tamamo-no-Mae terrified people because she out-performed an entire court on her own steam. And the possession material is about how hard it is to argue your way back out of a description once your neighbors have settled on it.
Bell was studying one consonant. The tales are working the same reflex at the scale of an entire person, which is where you cross into symbolism: the fox is competent in two worlds and native to neither, and that's a part human beings have needed a character to play in every century we've had one. If you want the flat reading, it's folklore doing its ordinary work: a real animal that hunts at night and likes the edge of a village better than the woods, given a story big enough to hold how uneasy that makes the village.
The unknown number, again
So. I've been sitting with the fox wife, and with the part where she gets found out.
Nothing about the years gets retracted in those stories. Nobody says the house she kept was a set or the children were props. Her nature becomes visible, that's all, and once it's visible the arrangement can't continue, so she goes back to the fields, and in some versions she comes back at night to look at the children through the window.
Which brings me back to Bell's newsreaders, walking out of one studio and into the next one down the hall and coming out twenty percent different on the other side.
Not one of them was doing an impression. There's no bulletin any of them read in a true voice and no station that got issued the counterfeit. Two audiences turned up, and each audience got the version it could actually hear, which happens to be the entire job description of a messenger. Twelve hundred years of fox stories and not one of them treats her as a fox in a wig, either. She's both, all the way down, and the trouble only ever starts when somebody watches the change happen and demands to know which one of them signed for the years.
So I've stopped hunting for the one underneath mine, and I'd suggest you stop too, because the four-percent countess and the one my family gets and the calm one on the work call are all of them me, working the same shift, and the fox never had an original face either and she still ran that household better than anybody in it.
