This is a wooden mask used in traditional Japanese theater (Noh/Kyogen). Type: Made of wood (with an aged orange-brown grain), it features adjustable knots (for securing it to the face). It belongs to the Kyogen mask category (Kyogen is a comedic genre within Noh), and its design resembles an old man's mask. Characteristics: A round, plump face, feathered eyebrows (pom-pom style), a small mustache, and a humorous, gentle expression. It is a typical mask for "commoner old man" characters in Kyogen. Function: Used for commoner and elderly characters in Kyogen plays; its style is more lifelike and comedic than Noh masks. Identification: The "Wangchun" stamp on the forehead is the sculptor's signature, indicating the mask was made by a specific craftsman. "Wangchun" is the signature of a mask maker from the mid-to-late Edo period. These craftsmen were mainly active in the Edo (present-day Tokyo) region during the 18th and 19th centuries. Therefore, this mask was most likely made in the late Edo period (approximately late 18th-19th century). Dimensions: Approximately 13.8 x 11.4 cm (length x width)
