Tengu are supernatural beings originating from Japanese folklore and religious traditions, typically depicted as mysterious figures combining human and avian traits, associated with mountain asceticism and martial arts. Common elements include red masks (with long noses or beak-like features), wings, yamabushi-style attire (monk robes and head coverings), wooden sandals, fans (uchiwa or feather fans), and accessories symbolizing training and combat. The overall design emphasizes authority, mystery, and a warrior-like presence, creating a solemn, spiritual visual image rooted in traditional Japanese mountain and yokai culture.
