Nagaita Chugata is a traditional Japanese stencil dyeing technique known for its reversible patterns achieved by applying resist paste to both sides of the fabric before immersing it in indigo dye. The method’s name refers to the long board, roughly 5.4 meters, used to stretch the cloth, and to the medium-sized patterns that fall between komon (small) and omon (large). Commonly used during the Edo period for dyeing cotton yukata worn by everyday people, the technique relies on Ise stencils, hand-made rice paste, and natural indigo. Today, artisans continue the tradition while innovating with materials such as hemp and silk, expanding its artistic expression beyond yukata.
