Kudzu appears in Nihon Shoki (Chronicles of Japan, 8th Century) and Man’yoshu (Collection of Myriad Leaves), and is considered one of the symbols of Nara.
People have loved its flowers since ancient times, and its roots have been used to produce kudzu-yu, kudzu-mochi, medicines, and other products.
The yarn used in this project is a reused fiber made from kudzu washi: leftover kudzu powder from the production of Yoshino kudzu which would otherwise end up as waste is ground finely, kneaded into washi (fibrous Japanese paper), then incorporated with natural cotton yarn.
The raw material used is from the root that remains after the production of Yoshino kudzu.
The kudzu root is ground into a powder 20 microns in diameter, which is then strained into washi paper to make kudzu washi.
Thin strips of this kudzu washi are then entwined with natural cotton to form the fibrous threads.
