Tengu

Mythological Narrative
The classic daitengu has a scarlet face and a towering nose, dresses like a yamabushi mountain ascetic, walks on single-toothed geta, and carries a feather fan that can raise gales; it roosts in ancient cryptomeria high in the mountains. Its lesser kin, the karasu-tengu, keep a crow's beak and wings. Every famous peak has its own great tengu, such as Sojobo of Mount Kurama, Tarobo of Mount Atago, and Jirobo of Mount Hira, and a folk text known as the Tengu Sutra lists forty-eight of them by mountain and name.
The word itself is Chinese, originally naming an ominous meteor, the 'celestial dog.' The Nihon Shoki records that in 637 a great star crossed the sky from east to west with a sound like thunder, and the monk Min, trained in China, identified it as a tengu. From the Heian period the creature moved into Buddhist lore: arrogant monks were said to fall after death into the 'tengu realm,' and the Konjaku Monogatarishu tells of tengu impersonating Buddhas and carrying off priests. The Muromachi noh play Kurama Tengu has the great tengu of Mount Kurama teach swordsmanship to the boy Ushiwakamaru, the future Minamoto no Yoshitsune, fixing Kurama as the cult's chief holy ground.
In village belief tengu explained mountain strangeness: children lost to 'spiriting away,' phantom tree-felling heard at night, stones flung from nowhere. The red long-nosed mask remains the face of the uncanny mountain.
Scholarly Commentary & Evolution
## From Kite-Demon to Mountain Tutor
Early tengu (Nihon ryōiki, Heike) are disruptive kite-goblins who possess monks and start wars. Later yamabushi-tengu of Mt. Kurama teach sword work to Yoshitsune. The long nose and red face are medieval iconography, not Kojiki fauna.
Danger sits in the middle: they punish arrogance more often than they eat travelers.
## Sōjōbō and Kurama
Tradition names Sōjōbō, the great tengu of Mount Kurama north of Kyoto, as the teacher who trained the young Minamoto no Yoshitsune in swordsmanship. Tengu were associated with the mountain ascetics called yamabushi, whose dress they share in art. Two main forms appear: the crow tengu (karasu-tengu) with a beak, and the long-nosed red-faced daitengu, the form fixed by later masks and prints.
