Late Meiji (1890 to 1912) Japanese ceramic netsuke representing a Kyogen theater mask of Bishamon - one of the 7 Gods of Good Fortune. He is a God of riches, an equivalent of Vaishravana, and thus is the protector of the Northern direction. Crisp detailing, great severe face, white enamel highlights, slight darkening of protruding parts from wear, overall in excellent condition. Impressed with seal ONKO on the back - the piece was made by a member of the Shimizu family producing Onko wares in Akasaka, Gifu Prefecture, most probably by Shimizu Sekisen I. Height 1 7/16 inches.
