The Kawazu mask suggests a frog, from which it gets its name. Representing a ghost of a man who was drowned, it expresses a human obsession. Its small but widely spaced eyes are casting a downward look, both eyebrows are united to protrude over the eyes like an eave, and the cheeks are hollowed, all of which impart a haggard and miserable expression. The wet-looking hair painted on the forehead, which suggests recent emersion from water, emphasizes the misery. Classified in the same category as the Yase-otoko mask, the Kawazu mask expresses an even stronger feeling of grudge. This mask has several versions. The Kawazu mask is used for such plays as “Akogi” and “Fujito.”
