Yuki Tsumugi Silk Weaving

結城紬 (Yuki Tsumugi)

Yuki Tsumugi (結城紬) is a UNESCO inscribed silk weaving tradition of Yuki City on the Ibaraki-Tochigi border — producing the most highly valued everyday silk textile in Japan, prized for its light weight, warmth, and characteristic handspun texture. The technical foundation is three sequential hand processes that all other Japanese silk textiles have mechanized: hand-reeling cocoons into tsumugi thread (手紡ぎ tebiki — drawing fiber from water-soaked cocoons by hand), hand-spinning the reeled fiber into yarn (手績み tetsumi — joining fiber lengths by hand-twisting at the fingertip), and hand-weaving on a back-strap loom. The tetsumi joining technique — where the weaver joins short fiber lengths into continuous yarn by wetting the fiber end with tongue, twisting it against the previous end with fingertip rotation — is the defining technique.
