Mikuriya Dyeing and Weaving is a traditional craft from Gotemba City, Shizuoka Prefecture. Practiced since the Edo period, it uses only natural Awa indigo, fermented in earthen-buried vats with lye from wood ash, lime, bran, and sake—without any chemicals. This gentle, time-honored method strengthens threads and fabrics by over 50% while producing a deep, rich indigo color beloved in Japan for centuries. The process involves repeatedly dipping threads or cloth dozens of times to achieve the desired shade, with designs created through techniques such as long board stencil dyeing, tsutsugaki freehand resist, and tie-dyeing. In addition to indigo, plant-based dyes are used to produce a range of colors, and fabrics from narrow strips to wide bolts are woven by hand into tsumugi kimono cloth, clothing, and accessories. Many works feature traditional patterns carved from stencils passed down since the workshop’s founding, blending historical artistry with enduring craftsmanship.
