The Hannya mask is a type of Noh mask representing a vengeful female ghost, characterized by jealousy and resentment.
Design: The Hannya is a demonic woman’s mask with two long horns painted with gold lacquer on the forehead. The top of the head features hair parted to the sides, and in the case of the Hannya, the hair is disheveled to convey ferocity. The eyebrows are artificial, and the eyes are golden, with only the pupils being open holes. The mouth is wide open, revealing upper and lower teeth fitted with metal fixtures and two pairs of fangs. A distinctive feature of the Hannya mask is that the upper half has a sorrowful expression, while the lower half with the widely opened mouth expresses intense anger.
