Most of Japan's wool production is not upgraded, as each farm produces only a few tens or hundreds of kilos, and such small quantities are normally not sufficient for industrial use. Since 2018, Kasagi Fiber Studio has been grazing its own sheep on a small family farm and has created a local processing circuit to fabricate high-quality wool products. Typically, wool quality is determined by the fineness of the fibers, but Kasagi Fiber Studio has developed a method of producing apparel fabrics infused with the wool's original texture, warmth and elasticity. This specialized know-how makes it possible to transform previously unused wool resources into superior-quality products.
