Yūki-tsumugi (結城紬) is a variety of silk cloth produced in Japan, chiefly in Yūki in Ibaraki Prefecture.

[1] The traditional history of yūki-tsumugi traces its origin to a crafthouse known as Nagahatabeno Ashiginu during the reign of the legendary Emperor Sujin[1] Knowledge of the method of silk production, developed by its founder, Ooyanomikoto, was said to have immediately spread out to the Yūki district and beyond.

It is said that the feudal lord of a farmer family in the Hitachi Province sent tsumugi fabric to a governor called Kamakura Kanryo every year as a gift.

[3][5] The technique involves a tedious process of manually tying thousands of resists before the yarn is dyed, based on the desired resulting pattern or design.

[8] The Association for the Preservation of the Honba Yūki-tsumugi Weaving Technique (本場結城紬技術保持会) was established in 1976 and helps promote and transmit the craft.
