This Noh mask is a faithful reproduction based on a treasured mask from the Ii family, the leading hereditary vassals of the Tokugawa clan and the lords of the large Hikone domain, which held 350,000 koku. The material is Kiso hinoki cypress that has been naturally dried for a long period. The colors are based on ancient traditions, using glue and gofun (powdered oyster shell) mixed together for the base coat, which is applied in 20-30 layers. Aging effects have been applied to give it a sense of history. The artist hopes that this mask will be used on a Noh stage. The book is for photography purposes only.
