Zazanza-ori is a silk textile produced in Hamamatsu, Shizuoka Prefecture. It is a striped fabric woven with tama-ito (silk spun from tama-mayu, double cocoons created by two silkworms). Because the threads from double cocoons are entangled and can only be drawn out by hand, the yarn has natural variations in thickness, giving the fabric a distinctive texture. The weaving uses softly twisted silk threads, often dyed with plant-based dyes, resulting in stripes with a refined, natural tone. Zazanza-ori was created in 1929 by Mr. Minoru Hiramatsu of Nakajima, Hamamatsu, who began experimenting with artistic weaving in 1928. Its name derives from a local legend: Shogun Ashikaga Yoshinori once recited a poem under a pine tree in Hamamatsu—“The sound of Hamamatsu is zazan-za”—inspired by the rustling wind through the pines. Still handwoven on traditional looms, Zazanza-ori becomes increasingly supple the more it is worn, developing a natural sheen and highlighting the intrinsic beauty of silk. Today it is considered a rare and highly prized craft textile.
