The material is Japanese cypress (hinoki). The size is 210mm in height, 168mm in width, and 111mm in depth, with a weight of 325g. The front is painted with authentic gofun (oyster shell pigment), and the back is finished with a dark, almost black, burnt brown lacquer. Although thinly carved, it weighs 325g, and therefore, copper plates are not used for the eyes; instead, gold-colored pigments are used, similar to the teeth. The craftsmanship is so subtle that it's not noticeable unless pointed out. While the construction is authentic, it is not for stage use, but rather a decorative mask intended to create a dignified atmosphere in an entryway or alcove (tokonoma).
