The Ainu are the original inhabitants of the northern islands of Japan and far eastern areas of present day Russia. Their most characteristic item of clothing is the attush, made from the fibres of a Japanese elm tree. Historically, attush used for ceremonial purposes were decorated on the collar, sleeves, back and hem with patterns in blue and black appliqué (iechunu) and further embroidered with line work. Geometric designs related to ancestor- and nature-worship – including bear, owl and killer-whale gods – were passed down from generation to generation.
