Originating from the Bizen area of Okayama. UNSAI weaving was traditionally used for creating durable Jika-tabi soles to protect the feet of workers. However. with the rise of mass production and efficiency. this ancient weaving technique was nearly lost. Rediscovered in the modern era as Itto UNSAI. the process now utilizes the rare Belgian shuttle loom. PICANOL. to create a fabric with unparalleled quality and texture. Every detail is meticulously crafted through countless repetitions on the loom. resulting in a single warp and weft threads of outstanding density and appearance.
