This is the Kyogen mask of the character Buaku. Kyogen is classical comic theatre. The faintly comical demon mask of Buaku is the Kyogen version of the Noh theatre mask of Beshimi. Both the characterization and stylised carving of this mask reflect the original prototype. The mask is carved from a single piece of cypress, with the features in high relief. The surface has been treated with a layer of gofun that has been painted a deep flesh colour. The folds of flesh around the eyes, cheeks, brow and mouth have been accentuated by painting the creases in a deep red colour with additional highlights in black ink (sumi). Black ink, applied in firm, yet sensitive lines, has also been used for the hair, eyebrows, moustache and whiskers. The eyeballs have had gold leaf applied, with the edges emphasized by lines of ink accentuated by red painted rims. This follows the Noh theatre tradition of colouring the eyes of a demon red and gold.
