Established in 1911, the company has continued to pass on the traditional Japanese industry of Wasarashi, a traditional method that takes cotton fabric that is tightly knit with thin fibers and boils it for 2 days to treat and remove any impurities in the cotton. This creates Sarashi which has great water-absorbent and quick-drying capabilities. Originally manufacturing Sarashi for the demand of hand towels, underwear, or medical supplies at that time, Sasasa continues to create new products that follow modern times with more people interested in the eco-conscious lifestyle.
