小千谷縮 Ojiya chijimi textiles
Ojiya chijimi textiles (called Ojiya chijimi in Japanese) is a handicraft produced from ramie in the area around the city of Ojiya in Niigata prefecture. The most notable feature of Ojiya chijimi is the process of exposing the fabric to snow, which utilizes the bleaching effect from ozone produced when snow evaporates in the sun. The ramie material encourages the evaporation of sweat and dries quickly, so kimono made from it have a pleasantly cool feeling. Because of the natural wrinkling, Ojiya chijimi kimono have a refreshing texture which is excellent during the intense humidity of Japanese summers, making it popular throughout the country.
