Tengu (/ˈtɛŋɡuː/ TENG-goo; Japanese: 天狗, pronounced [teŋɡɯ], lit. 'Heavenly Dog') are a type of legendary creature found in Shinto belief. They are considered a type of yōkai (supernatural beings) or Shinto kami (gods or spirits). The Tengu were originally thought to take the forms of birds of prey and a monkey deity, and they were traditionally depicted with human, monkey, and avian characteristics. Sarutahiko Ōkami is considered to be the original model of Konoha-Tengu (a supernatural creature with a red face and long nose), which today is widely considered the Tengu's defining characteristic in the popular imagination. He is the Shinto monkey deity who is said to shed light on Heaven and Earth. Some experts theorize that Sarutahiko was a sun god worshiped in the Ise region prior to the popularization of Amaterasu.
