Tengu (天狗, "heavenly dog") are a type of legendary creature found in Japanese folk religion and are also considered a type of Shinto god (kami) or yōkai (supernatural beings). Although they take their name from a dog-like Chinese demon (Tiangou), the tengu were originally thought to take the forms of birds of prey, and they are traditionally depicted with both human and avian characteristics. The earliest tengu were pictured with beaks, but this feature has often been humanized as an unnaturally long nose, which today is widely considered the tengu's defining characteristic in the popular imagination.
Buddhism long held that the tengu were disruptive demons and harbingers of war. Their image gradually softened, however, into one of protective, if still dangerous, spirits of the mountains and forests. Tengu are associated with the ascetic practice known as Shugendō, and they are usually depicted in the distinctive garb of its followers, the yamabushi.

The tengu in art appears in a large number of shapes, but it usually falls somewhere between a large, monstrous bird and a wholly anthropomorphized being, often with a red face or an unusually large or long nose. Early depictions of tengu show them as kite-like beings who can take a human-like form, often retaining avian wings, head or beak. The tengu's long nose seems to have been conceived in the 14th century, likely as a humanization of the original bird's bill. The tengu's long noses ally them with the Shinto deity Sarutahiko, who is described in the Japanese historical text, the Nihon Shoki, with a similar proboscis measuring seven hand-spans in length. In village festivals the two figures are often portrayed with identical red, phallic-nosed mask designs.
Some of the earliest representations of tengu appear in Japanese picture scrolls, such as the Tenguzōshi Emaki (天狗草子絵巻), painted c. 1296, which parodies high-ranking priests by endowing them the hawk-like beaks of tengu demons. Tengu are often pictured as taking the shape of some sort of priest. Beginning in the 13th century, tengu came to be associated in particular with the yamabushi, the mountain ascetics who practice Shugendō. The association soon found its way into Japanese art, where tengu are most frequently depicted in the yamabushi's distinctive costume, which includes a small black cap (頭襟 tokin) and a pom-pommed sash (結袈裟 yuigesa). Due to their priestly aesthetic, they are often shown wielding the Shakujo, a distinct staff used by Buddhist monks.
Tengu are commonly depicted holding magical ha-uchiwa (羽団扇 "feather fan"), fans made of feathers. In folk tales, these fans sometimes have the ability to grow or shrink a person's nose, but usually they are attributed the power to stir up great winds. Various other strange accessories may be associated with tengu, such as a type of tall, one-toothed geta sandal often called tengu-geta.
The term tengu and the characters used to write it are borrowed from the name of a fierce demon from Chinese folklore called tiāngoǔ. Chinese literature assigns this creature a variety of descriptions, but most often it is a fierce and anthropophagous canine monster that resembles a shooting star or comet. It makes a noise like thunder and brings war wherever it falls. One account from the Shù Yì Jì (述異記, "A Collection of Bizarre Stories"), written in 1791, describes a dog-like tiāngoǔ with a sharp beak and an upright posture, but usually tiāngoǔ bear little resemblance to their Japanese counterparts.
The 23rd chapter of the Nihon Shoki, written in 720, is generally held to contain the first recorded mention of tengu in Japan. In this account a large shooting star appears and is identified by a Buddhist priest as a "heavenly dog", and much like the tiāngoǔ of China, the star precedes a military uprising. Although the Chinese characters for tengu are used in the text, accompanying phonetic furigana characters give the reading as amatsukitsune (heavenly fox). M.W. de Visser speculated that the early Japanese tengu may represent a conglomeration of two Chinese spirits: the tiāngoǔ and the fox spirits called huli jing.
How the tengu was transformed from a dog-meteor into a bird-man is not clear. Some Japanese scholars have supported the theory that the tengu's image derives from that of the Hindu eagle deity Garuda, who was pluralized in Buddhist scripture as one of the major races of non-human beings. Like the tengu, the garuda are often portrayed in a human-like form with wings and a bird's beak. The name tengu seems to be written in place of that of the garuda in a Japanese sutra called the Emmyō Jizō-kyō (延命地蔵経), but this was likely written in the Edo period, long after the tengu's image was established. At least one early story in the Konjaku Monogatari describes a tengu carrying off a dragon, which is reminiscent of the garuda's feud with the nāga serpents. In other respects, however, the tengu's original behavior differs markedly from that of the garuda, which is generally friendly towards Buddhism. De Visser has speculated that the tengu may be descended from an ancient Shinto bird-demon which was syncretized with both the garuda and the tiāngoǔ when Buddhism arrived in Japan. However, he found little evidence to support this idea.
A later version of the Kujiki, an ancient Japanese historical text, writes the name of Amanozako, a monstrous female deity born from the god Susanoo's spat-out ferocity, with characters meaning tengu deity (天狗神). The book describes Amanozako as a raging creature capable of flight, with the body of a human, the head of a beast, a long nose, long ears, and long teeth that can chew through swords. An 18th-century book called the Tengu Meigikō (天狗名義考) suggests that this goddess may be the true predecessor of the tengu, but the date and authenticity of the Kujiki, and of that edition in particular, remain disputed.
Evil spirits and angry ghosts
The Konjaku Monogatari, a collection of stories published in the late Heian Period, contains some of the earliest tales of tengu, already characterized as they would be for centuries to come. These tengu are the troublesome opponents of Buddhism, who mislead the pious with false images of the Buddha, carry off monks and drop them in remote places, possess women in an attempt to seduce holy men, rob temples, and endow those who worship them with unholy power. They often disguise themselves as priests or nuns, but their true form seems to be that of a kite.
Throughout the 12th and 13th centuries, accounts continued of tengu attempting to cause trouble in the world. They were now established as the ghosts of angry, vain, or heretical priests who had fallen on the "tengu-realm" (天狗道, tengudō). They began to possess people, especially women and girls, and speak through their mouths (kitsunetsuki). Still the enemies of Buddhism, the demons also turned their attention to the royal family. The Kojidan tells of an Empress who was possessed, and the Ōkagami reports that Emperor Sanjō was made blind by a tengu, the ghost of a priest who resented the throne.
One notorious tengu from the 12th century was himself the ghost of an emperor. The Hōgen Monogatari tells the story of Emperor Sutoku, who was forced by his father to abandon the throne. When he later raised the Hōgen Rebellion to take back the country from Emperor Go-Shirakawa, he was defeated and exiled to Sanuki Province on Shikoku. According to legend he died in torment, having sworn to haunt the nation of Japan as a great demon, and thus became a fearsome tengu with long nails and eyes like a kite's.
In stories from the 13th century, tengu began to abduct young boys as well as the priests they had always targeted. The boys were often returned, while the priests would be found tied to the tops of trees or other high places. All of the tengu's victims, however, would come back in a state of near death or madness, sometimes after having been tricked into eating animal dung.
The tengu of this period were often conceived of as the ghosts of the arrogant, and as a result the creatures have become strongly associated with vanity and pride. Today the Japanese expression tengu ni naru, literally, "becoming a tengu", is still used to describe a conceited person.
Great and small demons
In the Genpei Jōsuiki, written in the late Kamakura period, a god appears to Go-Shirakawa and gives a detailed account of tengu ghosts. He says that they fall onto the tengu road because, as Buddhists, they cannot go to Hell, yet as people with bad principles, they also cannot go to Heaven. He describes the appearance of different types of tengu: the ghosts of priests, nuns, ordinary men, and ordinary women, all of whom in life possessed excessive pride. The god introduces the notion that not all tengu are equal; knowledgeable men become daitengu (大天狗, greater tengu), but ignorant ones become kotengu (小天狗, small tengu).
A section of the Tengu Meigikō, later quoted by Inoue Enryō, lists the daitengu in this order:
- Sōjōbō (僧正坊) of Mount Kurama
- Tarōbō (太郎坊) of Mount Atago
- Jirōbō (二郎坊) of the Hira Mountains
- Sanjakubō (三尺坊) of Mount Akiba
- Ryūhōbō (笠鋒坊) of Mount Kōmyō
- Buzenbō (豊前坊) of Mount Hiko
- Hōkibō (伯耆坊) of Daisen (mountain)
- Myōgibō (妙義坊) of Mount Ueno (Ueno Park)
- Sankibō (三鬼坊) of Itsukushima
- Zenkibō (前鬼坊) of Mount Ōmine
- Kōtenbō (高天坊) of Katsuragi
- Tsukuba-hōin (筑波法印) of Hitachi Province
- Daranibō (陀羅尼坊) of Mount Fuji
- Naigubu (内供奉) of Mount Takao
- Sagamibō (相模坊) of Shiramine
- Saburō (三郎) of Mount Iizuna
- Ajari (阿闍梨) of Higo Province
Daitengu are often pictured in a more human-like form than their underlings, and due to their long noses, they may also called hanatakatengu (鼻高天狗, tall-nosed tengu). Kotengu may conversely be depicted as more bird-like. They are sometimes called Karasu-Tengu (烏天狗, crow tengu), or koppa- or konoha-tengu (木葉天狗, 木の葉天狗foliage tengu). Inoue Enryō described two kinds of tengu in his Tenguron: the great daitengu, and the small, bird-like konoha-tengu who live in Cryptomeria trees. The konoha-tengu are noted in a book from 1746 called the Shokoku Rijin Dan (諸国里人談), as bird-like creatures with wings two meters across which were seen catching fish in the Ōi River, but this name rarely appears in literature otherwise.
Creatures that do not fit the classic bird or yamabushi image are sometimes called tengu. For example, tengu in the guise of wood-spirits may be called guhin (occasionally written kuhin) (狗賓 dog guests), but this word can also refer to tengu with canine mouths or other features. The people of Kōchi Prefecture on Shikoku believe in a creature called shibaten or shibatengu (シバテン, 芝天狗, lawn tengu), but this is a small childlike being who loves sumō wrestling and sometimes dwells in the water, and is generally considered one of the many kinds of kappa. Another water-dwelling tengu is the kawatengu (川天狗, river tengu) of the Greater Tokyo Area. This creature is rarely seen, but it is believed to create strange fireballs and be a nuisance to fishermen.
Protective spirits and deities
The Shasekishū, a book of Buddhist parables from the Kamakura period, makes a point of distinguishing between good and bad tengu. The book explains that the former are in command of the latter and are the protectors, not opponents, of Buddhism - although the flaw of pride or ambition has caused them to fall onto the demon road, they remain the same basically good, dharma-abiding persons they were in life.
The tengu's unpleasant image continued to erode in the 17th century. Some stories now presented them as much less malicious, protecting and blessing Buddhist institutions rather than menacing them or setting them on fire. According to a legend in the 18th-century Kaidan Toshiotoko (怪談登志男), a tengu took the form of a yamabushi and faithfully served the abbot of a Zen monastery until the man guessed his attendant's true form. The tengu's wings and huge nose then reappeared. The tengu requested a piece of wisdom from his master and left, but he continued, unseen, to provide the monastery with miraculous aid.
In the 18th and 19th centuries, tengu came to be feared as the vigilant protectors of certain forests. In the 1764 collection of strange stories Sanshu Kidan (三州奇談), a tale tells of a man who wanders into a deep valley while gathering leaves, only to be faced with a sudden and ferocious hailstorm. A group of peasants later tell him that he was in the valley where the guhin live, and anyone who takes a single leaf from that place will surely die. In the Sōzan Chomon Kishū (想山著聞奇集), written in 1849, the author describes the customs of the wood-cutters of Mino Province, who used a sort of rice cake called kuhin-mochi to placate the tengu, who would otherwise perpetrate all sorts of mischief. In other provinces a special kind of fish called okoze was offered to the tengu by woodsmen and hunters, in exchange for a successful day's work. The people of Ishikawa Prefecture have until recently believed that the tengu loathe mackerel, and have used this fish as a charm against kidnappings and hauntings by the mischievous spirits.
Tengu are worshipped as beneficial kami (gods or revered spirits) in various Japanese religious cults. For example, the tengu Saburō of Izuna is worshipped on that mountain and various others as Izuna Gongen (飯綱権現, incarnation of Izuna), one of the primary deities in the Izuna Shugen cult, which also has ties to fox sorcery and the Dakini of Tantric Buddhism. Izuna Gongen is depicted as a beaked, winged figure with snakes wrapped around his limbs, surrounded by a halo of flame, riding on the back of a fox and brandishing a sword. Worshippers of tengu on other sacred mountains have adopted similar images for their deities, such as Sanjakubō (三尺坊) or Akiba Gongen (秋葉権現) of Akiba and Dōryō Gongen (道了権現) of Saijō-ji Temple in Odawara.
In popular folk tales
Tengu appear frequently in the orally-transmitted tales collected by Japanese folklorists. As these stories are often humorous, they tend to portray tengu as ridiculous creatures who are easily tricked or confused by humans. Some common folk tales in which tengu appear include:
- "The Tengu's Magic Cloak" (天狗の隠れみの Tengu no Kakuremino): A boy looks through an ordinary piece of bamboo and pretends he can see distant places. A tengu, overwhelmed by curiosity, offers to trade it for a magic straw cloak that renders the wearer invisible. Having duped the tengu, the boy continues his mischief while wearing the cloak. Another version of this story tells of an ugly old man who tricks a tengu into giving him his magical cloak and causes mayhem for his fellow villagers. The story ends with the tengu regaining the coat through a game of riddle exchange and punishes the man by turning him into a wolf.
- "The Old Man's Lump Removed" (瘤取り爺さん Kobu-tori Jiisan): An old man has a lump or tumor on his face. In the mountains he encounters a band of tengu making merry and joins their dancing. He pleases them so much that they want him to join them the next night, and offer a gift for him. In addition, they take the lump off his face, thinking that he will want it back and therefore have to join them the next night. An unpleasant neighbor, who also has a lump, hears of the old man's good fortune and attempts to repeat it, and steal the gift. The tengu, however, simply give him the first lump in addition to his own, because they are disgusted by his bad dancing, and because he tried to steal the gift.
- "The Tengu's Fan" (天狗の羽団扇 Tengu no Hauchiwa) A scoundrel obtains a tengu's magic fan, which can shrink or grow noses. He secretly uses this item to grotesquely extend the nose of a rich man's daughter, and then shrinks it again in exchange for her hand in marriage. Later he accidentally fans himself while he dozes, and his nose grows so long it reaches heaven, resulting in painful misfortune for him.
- "The Tengu's Gourd" (天狗の瓢箪 "Tengu no Hyōtan"): A gambler meets a tengu, who asks him what he is most frightened of. The gambler lies, claiming that he is terrified of gold or mochi. The tengu answers truthfully that he is frightened of a kind of plant or some other mundane item. The tengu, thinking he is playing a cruel trick, then causes money or rice cakes to rain down on the gambler. The gambler is of course delighted and proceeds to scare the tengu away with the thing he fears most. The gambler then obtains the tengu's magic gourd (or another treasured item) that was left behind.
- "The Tengu, and the Woodcutter": A tengu bothers a woodcutter, showing off his supernatural abilities by guessing everything the man is thinking. The woodcutter swings his axe, and a splinter of wood hits the tengu on the nose. The tengu flees in terror, exclaiming that humans are dangerous creatures who can do things without thinking about them.
During the 14th century, the tengu began to trouble the world outside of the Buddhist clergy, and like their ominous ancestors the tiāngoǔ, the tengu became creatures associated with war. Legends eventually ascribed to them great knowledge in the art of skilled combat.
This reputation seems to have its origins in a legend surrounding the famous warrior Minamoto no Yoshitsune. When Yoshitsune was a young boy going by the name of Ushiwaka-maru, his father, Yoshitomo, was assassinated by the Taira clan. Taira no Kiyomori, head of the Taira, allowed the child to survive on the grounds that he be exiled to the temple on Mount Kurama and become a monk. But one day in the Sōjō-ga-dani Valley, Ushiwaka encountered the mountain's tengu, Sōjōbō. This spirit taught the boy the art of swordsmanship so that he might bring vengeance on the Taira.
Originally the actions of this tengu were portrayed as another attempt by demons to throw the world into chaos and war, but as Yoshitsune's renown as a legendary warrior increased, his monstrous teacher came to be depicted in a much more sympathetic and honorable light. In one of the most famous renditions of the story, the Noh play Kurama Tengu, Ushiwaka is the only person from his temple who does not give up an outing in disgust at the sight of a strange yamabushi. Sōjōbō thus befriends the boy and teaches him out of sympathy for his plight.
Two stories from the 19th century continue this theme: In the Sōzan Chomon Kishū, a boy is carried off by a tengu and spends three years with the creature. He comes home with a magic gun that never misses a shot. A story from Inaba Province, related by Inoue Enryō, tells of a girl with poor manual dexterity who is suddenly possessed by a tengu. The spirit wishes to rekindle the declining art of swordsmanship in the world. Soon a young samurai appears to whom the tengu has appeared in a dream, and the possessed girl instructs him as an expert swordsman. Some rumors surrounding the ninja indicate that they were also instructed by the tengu.
In popular culture
Profoundly entrenched in the Japanese imagination for centuries, tengu continue to be popular subjects in modern fiction, both in Japan and increasingly in other countries. They often appear among the many characters and creatures featured in Japanese cinema, animation, comics, and video games.
In the anime Shinzo, the Bird Enterran named Lord Caris has a Tengu-like appearance.
In the anime/manga Hakkenden: Touhou Hakken Ibun , Kagetsu and Hazuki are twin Tengu brothers. Shinobu Inue is half Tengu because of his Tengu Father (Kagetsu) and Human Mother. Kagetsu gave him part of his soul in order to save him, and later on died because he used up his remaining powers. Hazuki (Shinobu's 'uncle') is now Shinobu's foster father.
In the manga/anime One Piece, Usopp has a Tengu-like appearance. He is known for his trickery and using plants as weapons.

In Ninja Sentai Kakuranger, Mighty Morphin Power Rangers: The Movie, Mighty Morphin Power Rangers season 3, and Mighty Morphin Alien Rangers, the Tengu appears as a monster of the day/week (Kakuranger and Alien Rangers "adapted into Professor Longnose"), a queen Tengu monster which was a cut monster from the movie but appears in its Game Boy adaption as a boss, and as minions in the movie, season 3 of MMPR & the 10 episode Alien Ranger arc. In the movie, they are called the "Tengu Warriors". The suits for the Tengu Warriors are reused in the show and called the "Tenga Warriors". A Tengu-like monster known as Hit of the Tengu appears as a monster of the day in an episode of Tensou Sentai Goseiger (known as No-Joke in its American adaptation Power Rangers Megaforce). Another Tengu-like monster also serves as a monster of the day in an episode of Shuriken Sentai Ninninger.
A Tengu also appeared on the animated TV series Randy Cunningham: 9th Grade Ninja in the episode "Evil Spirit Week."
Graham Masterton's horror novel Tengu tells of a conspiracy by a secret Japanese society to avenge the American bombing of Hiroshima by producing invincible warriors possessed by the Tengu. It includes details of some of the mythology and rituals surrounding the Tengu. This novel in turn inspired the Necromantia song 'Circle of Burned Doves'.
A karasu-tengu appears in the movie Yokai Monsters: Spook Warfare.
A daitengu appears in the movie The Great Yokai War.
In the 2009 movie RoboGeisha the higher-ranking Geisha soldiers are called "Tengun" and wear red long-nosed masks modeled after the human form of the tengu. "Tengu Milk" is one of their attacks.

It is also found as a playable bird-like race in Dungeon Crawl Stone Soup.
In Super Mario Bros. 2, there is an enemy named Tweeter based on a Tengu.
An enemy based on the Tengu can be found in the 2006 game Okami. However this version is actually a bird or similar creature, which sports the Tengu-based mask.
The games Mega Man 8 and Mega Man and Bass also feature the boss character Tengu Man as one of Dr. Wily's creations. He is a very cocky and overconfident Robot Master, wielding the Tornado Hold (Mega Man 8) and the Tengu Blade (Mega Man and Bass). His appearance is based on the traditional red-faced mask with a long nose. An alternate version called TenguMan.EXE appears in MegaMan Battle Network 6 Cybeast Falzar.

In the dōjin soft game series Touhou Project, Inubashiri Momiji, Himekaidou Hatate, and Shameimaru Aya are stated to be tengu, although with their cute appearances and lack of typical Tengu features (such as long noses), they are primarily based on mythical tengu in behavior and function. Notably, while Hatate and Aya are crow based Tengu, Momiji is a "wolf" tengu, possibly referencing the canine (Tiangou) name source.
