What it is
Tengu are supernatural entities in Japan classified as yōkai or kami. They are depicted with human, monkey, and bird traits. Early forms resembled kites or hawks. Later images show a red face and an elongated nose. These features link them to the deity Sarutahiko Ōkami. Tengu are often shown wearing the robes of mountain priests. They hold a magical feather fan that can create storms. Some tales say the fan can change a person's nose size. They are also associated with tall, one-toothed wooden sandals. Their appearance varies from monstrous birds to fully human figures.
Where it comes from
The name likely comes from the Chinese tiāngōu, a fierce canine monster. This creature was described as a shooting star that brought war. The Nihon Shoki records a 'heavenly dog' star before a rebellion. Early readings used the term amatsukitsune. Scholars suggest the image merged Chinese spirits with local Japanese kami. Another theory links tengu to the Hindu Garuda. Stories of tengu abducting dragons resemble Garuda's fights with serpents. A disputed text links them to Amanozako, a goddess born from rage. Her description includes a long nose and beast head. Most experts see tengu as a distinct evolution of Japanese folklore.
How it is done
Tengu are not performed but are believed to inhabit forests. They were once thought to possess people, especially women. They would speak through the possessed to cause trouble. They targeted monks and royal family members. Victims were often found tied to high trees. Boys were abducted and returned in poor health. Priests were left near death or madness. Modern depictions show them teaching martial arts. Legends say they instructed Minamoto no Yoshitsune. They use their fans to stir winds or grant power. They are not rituals but active spiritual presences.
Tools and materials
The hauchiwa is a feather fan used by tengu. It represents their power over weather and humans. The shakujō is a monk's staff they carry. It signifies their connection to Buddhist ascetics. The tokin is a distinctive headwear worn by yamabushi. Pom-pom sashes accompany the priestly garb. Tall geta sandals are another common accessory. These items mark them as followers of Shugendō. The long nose is a key physical trait. It may derive from the beak of early bird forms.

What it is for
Tengu were originally feared as harbingers of war. They caused famine and military uprisings. Later, they became protectors of the mountains. They guard the forests and their inhabitants. They are still considered dangerous spirits. People avoid angering them due to past harms. Their association with pride remains strong. The phrase 'becoming a tengu' means being conceited. They test the humility of those who enter their domain. They reward those who respect the mountain traditions.
Who does it
Yamabushi are mountain ascetics linked to tengu. They practice Shugendō, a syncretic faith. Tengu are depicted wearing their specific robes. Scholars study the evolution of tengu imagery. Artists have portrayed them for centuries. Picture scrolls from the 13th century show early forms. These works often mocked corrupt priests. Modern media continues to feature tengu characters. They appear in art, literature, and festivals. No single group performs rituals for them today.
Peoples and places
Tengu are central to Japanese folklore. They are part of Shinto and Buddhist narratives. The Konjaku Monogatarishū contains early stories. These tales describe them as enemies of Buddhism. They misled pious followers and robbed temples. Emperor Sutoku was said to become a tengu after exile. His ghost haunted Japan as a great demon. Different regions have local variations. Kōchi Prefecture knows the shibatengu. Tokyo Area has the water-dwelling kawatengu. These creatures reflect local fears and beliefs.

What people believe
Tengu exist between heaven and hell. They cannot enter either realm due to their pride. They are the ghosts of arrogant priests and nobles. Their spirit realm is called tengudō. Knowledgeable men become greater tengu. Ignorant ones become smaller, bird-like forms. Daitengu are more human in appearance. Kotengu retain more avian features. They represent the danger of vanity. Their power comes from their spiritual status. They enforce humility in the natural world.
When it is done
No specific festivals are dedicated to tengu. They are present year-round in the mountains. Their origins are tied to historical events. The Nihon Shoki entry marks an early sighting. Festivals sometimes feature tengu masks. Village celebrations use red phallic-nosed designs. These masks link tengu to Sarutahiko Ōkami. The imagery appears in local cultural events. There are no set dates for tengu activities.
How scholars and sceptics see it
Researchers analyze tengu as cultural symbols. M. W. de Visser studied their Chinese connections. He noted the shift from demon to protector. Scholars debate the Amanozako origin theory. The Kujiki text date is considered unreliable. Linguists trace the term to Chinese tiāngōu. Art historians examine picture scroll depictions. These works reveal social commentary on priests. Psychologists view tengu as projections of pride. They embody the fear of unchecked ambition.
Cautions and what is closed
Tengu are not harmless. They were known to abduct children. Victims returned in severe distress. Possession cases caused mental instability. They targeted religious figures specifically. Their wrath was feared by the royal court. Modern interpretations soften this danger. They are now seen as quirky guardians. Historical texts emphasize their malevolence. Respect is required when entering their territory.
Compare and confuse
Tengu are often confused with other yōkai. They share traits with fox spirits. The early reading amatsukitsune highlights this link. They differ from kappa, though some overlap exists. The shibatengu is sometimes grouped with kappa. Chinese tiāngōu is a distant relative. Both bring war and resemble stars. Hindu Garuda shares the bird-human form. Tengu lack Garuda's friendly stance toward Buddhism.
