Nagoya Black Dyeing is the art used to make formal kimono. The black dyed cloth is designated as a Traditional Craft Product by Aichi Pref. The history of this art is dated back to the early Edo period (the 17th century), when Owari clan started to control dyeing industry for making clan banners and labarums. Later the dyeing of a black cloth with family crests for clan members and commoners began at the end of the Edo period (the 19th century). In order to make the outline of reversed-out family crest clear on black dyed cloth, a paper stencil is used. The mon-ate amitsuke technique, which is peculiar to Nagoya, is used. To create rich black color, the cloth is immersed in the dyestuff with low concentration for 30-40 minutes. The main products today are kimono cloth, haori, and mourning kimono. Kimono with a family crest is usually worn on formal occasions. Especially, mourning kimono is still worn by most people as the nation’s traditional clothing.
