Yaeyama Jōfu Ramie Weaving and Sea Bleaching

八重山上布 (Yaeyama Jōfu)

Yaeyama jōfu (八重山上布) is a fine ramie cloth from Ishigaki and Taketomi in the Yaeyama Islands, Japan's far southwest. It is famous for two things. The first is kuru (紅露, a wild yam, Dioscorea cirrhosa, whose northern limit is Ishigaki and Iriomote): its concentrated juice is rubbed onto the yarn with a bamboo brush to print ikat patterns (suri-komi nassen), a method no other Okinawan textile uses. The second is umi-zarashi, sea bleaching: the woven cloth is floated in the shallows of the sea to whiten the ramie and fix the printed color. Ramie weaving on the islands is attested by 1477, when shipwrecked Koreans on Yonaguni described it. Under Satsuma's control of Ryukyu, the islands' poll tax required women aged 15 to 50 to deliver ramie cloth: white kōnō-fu, and goyōfu woven exactly to pattern drawings (mīzu) sent from Shuri. That pressure refined the technique. After the tax was abolished in 1903, rubbed-dye printing on the ayatsuburu warp frame was devised and became the dominant method. Hand-tied (kukuri) kasuri was later revived by Arakaki Sachiko, a Living National Treasure since 2024.

Estimated Origin
Ramie weaving attested 1477 (Korean castaways on Yonaguni, recorded in the Annals of the Joseon Dynasty); formalized as poll-tax cloth under Satsuma rule from the early 17th century; printed (nassen) jōfu devised around the 1903 abolition of the poll tax
Cultural Function
Poll-tax cloth (kōnō-fu and goyōfu) under Satsuma-era Ryukyu; summer kimono
Primary Materials
Ramie (chōma, 'shiro-bū' white-leaved variety) — hand-spliced yarn for weft; spun ramie commonly used for warp since the late Meiji era
Primary Tools
Yaeyama-style high-warp loom (short, weighted, with separate ayatsuburu pattern beam and ground beam to reduce warp-ikat misalignment); ayatsuburu warp-printing frame; bamboo brush
Process Overview
Ramie cultivation -> fiber extraction and splicing -> warping and starching -> kasuri (hand-tied and dip-dyed, or rubbed-printed with kuru) -> beaming onto ayatsuburu and ground beam -> weaving on the Yaeyama loom -> sun-drying and seawater-lime bath -> umi-zarashi sea bleaching -> pestle finishing
Traditional Applications
Poll-tax cloth; summer garments
Contemporary Applications
Summer kimono, obi, tapestries, noren curtains; small goods
Notable Practitioners
