Deep in the mountains of Japan, among the cedar forests where the mountain ascetics trained, lived the tengu (天狗). They were creatures of the heights: part bird, part human, with wings, a fiery red face, and — in their most famous form — an enormously long nose. They could fly, change their shape, and command the wind. They were master swordsmen and tricksters. They kidnapped children and led monks astray with illusions, and they punished human pride. Yet they could also be protectors of the mountains and teachers of heroes.
The tengu is one of the most distinctive figures in Japanese folklore. Over a thousand years, it changed from a demonic bird to a proud mountain spirit to a guardian deity — and its long red face has become one of the most recognizable masks in Japan.
The Heavenly Dog
The name tengu is written with Chinese characters meaning “heavenly dog.” In China, the tiangou was a monstrous black dog believed to cause eclipses by eating the sun or moon, and a name for meteors or comets that fell with a roar. The word entered Japan along with Chinese learning. The Nihon Shoki (720 CE) records that in 637 a great star crossed the sky with a sound like thunder, and a Buddhist monk explained that it was not a shooting star but a tengu.
After this early mention, the tengu disappears from records for centuries. When it returns, it has taken a completely different form: not a dog, but a bird.
Two Kinds of Tengu
In Japanese folklore there are two main types:
- Karasu-tengu (“crow tengu”) are the older form. They have the head and beak of a bird of prey or crow, black feathered wings, and a human body. They are smaller, often wild and violent.
- Konoha-tengu or daitengu (“great tengu”) are the later and more famous form. They look like tall men with red faces, a long nose, wings, and the clothing of a yamabushi — the mountain ascetics of the Shugendō tradition — including a small black cap (tokin) and a feathered fan (hauchiwa) which they use to stir up great winds.
The long-nosed image became dominant from around the fifteenth century. Some scholars have suggested that it was influenced by the masks of Shinto deities such as Sarutahiko, the long-nosed god who guided the imperial grandson from heaven to earth, or by the masks of Gigaku, an ancient dance-drama.
Enemies of Buddhism
In the Heian and Kamakura periods (794–1333), tengu were regarded as demons hostile to Buddhism. They were said to be the reborn spirits of arrogant or corrupt monks — priests who had been proud of their learning or had misused their powers, and who, instead of attaining enlightenment, fell into the tengu-dō, the “tengu path,” a special realm of demons outside the six Buddhist realms of rebirth.
Tengu tormented monks by creating illusions: false Buddhas descending on clouds, visions of paradise, magical lights. The medieval collection Konjaku Monogatarishū (twelfth century) contains many stories of tengu who deceived monks and were exposed. In one, a tengu disguised as a Buddha appeared in a persimmon tree, and a sceptical minister stared at it until the illusion failed and the tengu fell to the ground as a kite with a broken wing.
Tengu were also said to kidnap people, especially children and young men, carrying them off into the mountains. Those who returned were dazed and told strange stories. The phenomenon was called tengu-kakushi, “hidden by the tengu” — a common explanation for a missing child. Even into the nineteenth century, famous cases were recorded; the scholar Hirata Atsutane interviewed a boy named Torakichi in 1820 who claimed to have lived among the tengu.
Pride and the Long Nose
In Japanese, to “become a tengu” (tengu ni naru) means to become conceited, and a proud person is said to have a “long nose.” The tengu’s association with arrogance — arrogant monks, arrogant warriors — runs throughout the tradition. Tengu punished pride but were themselves the embodiment of it.
Masters of the Sword
The most famous tengu legend is the story of Minamoto no Yoshitsune, the great warrior of the twelfth century. As a boy named Ushiwakamaru, Yoshitsune was sent to the temple of Kurama-dera in the mountains north of Kyoto. There, according to legend, he was trained in swordsmanship and military strategy by Sōjōbō, the king of the tengu, who lived in the valley of Sōjōgatani on Mount Kurama.
With the tengu’s training, Yoshitsune became the greatest swordsman and general of his age. He famously defeated the giant warrior-monk Benkei on the Gojō Bridge in Kyoto, leaping and dancing out of reach of his halberd. Benkei became his loyal follower.
The legend made tengu the patrons of martial arts, and many schools of swordsmanship claimed tengu origins for their techniques.
Great Tengu of the Mountains
By the Edo period, great tengu were regarded as powerful mountain spirits and protectors (kami), each associated with a particular sacred mountain. The most famous are:
- Sōjōbō of Mount Kurama, king of the tengu.
- Tarōbō of Mount Atago, near Kyoto.
- Jirōbō of Mount Hira.
- Saburō of Mount Izuna.
- Buzenbō of Mount Hiko in Kyushu.
- Hōkibō of Mount Daisen.
The mountain ascetics of Shugendō, who practised austerities in the mountains to gain spiritual power, were closely associated with tengu; tengu were often depicted in yamabushi dress, and the two were sometimes indistinguishable in folklore.
At Mount Takao, near Tokyo, the temple of Yakuōin has large statues of both a crow tengu and a long-nosed tengu, and tengu are revered as messengers of the mountain deity.
Tengu in Art and Festival
The red, long-nosed tengu mask is one of the most recognizable masks in Japan. It is worn in festivals, hung in homes as a charm, and used in kagura and Noh theatre. In many local festivals, a person in a tengu mask leads the procession, clearing the way, in the role of Sarutahiko.
Tengu Today
The tengu remains a popular figure in modern Japanese culture. It appears in anime, manga, and video games, from the Nurarihyon no Mago series to Nioh and the Pokémon Shiftry, based on the leaf-fan-wielding tengu. The tengu’s long nose is used in advertising, as a symbol of pride, and as a lucky charm. From demon to guardian, it has become an enduring emblem of the wild power of Japan’s mountains.
