The Ainu are an indigenous people of theislands of Hokkaido and Honshu in Japan, and Sakhalin and Kuril in Russia. Originally hunter-gatherers, they made clothing from many materials including animal hide, bird and fish skin. But the fabric perhaps most associated with the Ainu is attush, made from the bark of the elm and other trees which is soaked, made into yarn and woven. Garments could take many months to make, and are amongst the most spectacular designs of ethnic clothing in the world. As contact developed with Edo Japan, cotton and silk were incorporated into the garments, but the intricate designs are unique, and authentic vintage Ainu garments are now highly sought after and very expensive.
