Though both are rooted in Japanese supernatural tradition, Oni and Hannya masks represent distinct archetypes. Oni are demonic figures from folklore — typically depicted with horns, exaggerated tusks, and a ferocious expression meant to embody punishment and raw supernatural force. Hannya masks originate specifically from Noh theater and portray a female spirit transformed by overwhelming jealousy and sorrow. The Hannya's features — curved horns, a leering mouth, and hollow eyes — are designed to convey psychological anguish rather than brute power. In white colorways, this distinction becomes even more nuanced: a white Oni reads as spectral and otherworldly, while a white Hannya leans into themes of grief and the spirit realm. Collectors who understand this difference tend to display the two forms as deliberate contrasts, pairing fierce Oni pieces with more mournful Hannya designs to represent opposite poles of Japanese supernatural iconography.
