The Female Tengu is a strand within the broader image of tengu sporadically referenced in texts and oral lore. She is depicted in women’s attire such as kosode, light robes, or scarlet hakama, yet her back-borne wings and supernatural power mark her as a tengu. In The Tale of the Heike and its offshoots, the nun-tengu appears as a metamorphosis born from religious decline, providing a female counterpart to the monk-tengu. Edo-period mountain-encounter tales often stress prohibitions against women, noting the absence of female tengu, while river-tengu lore sporadically mentions married pairs or feminine features. Claims tracing their lineage to the goddess Amanozakoyahime appear in early modern natural-history writings but remain interpretive rather than doctrinal. Regional variation is great and no single image dominates, yet they share the general tengu attributes of might, illusion, and flight. Stripped of creative exaggeration, the Female Tengu is best seen as a projection of womanhood within the tengu world, with specific names and genealogies largely unknown.
