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 asanother attempt by demons to throw the world into chaos and war, but asYoshitsune's renown as a legendary warrior increased, his monstrousteacher came to be depicted in a much more sympathetic and honorablelight. 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.
