八重山上布 Yaeyama-jōfu

Yaeyama-jōfu, a tradition passed down primarily on the island of Ishigaki, has a history of being offered as a tribute cloth, through the royal court of the Ryūkyū Kingdom, to the Satsuma Domain during the Edo period. Also known as Shiro-jōfu (white fina ramie cloth), Yaeyama-jōfu is dried in the sun after weaving and bleached in seawater, a process that gains it an utterly clear whiteness. The ramic raw material and the vegetation from which the dyes are made all take maximum advantage of the blessings of the islands’ sun and sea. The umizarashi step of bleaching in seawater is now practiced only for Yaeyama-jōfu.
