Norens are curtains for doorways used in homes, businesses and restaurants. The Japanese have been using them for hundreds of years to great effect. In private homes, Japanese norens are used to separate rooms and doorways, while in businesses they are used with the intention of denoting the specialty of the shop. At restaurants, Japanese norens serve to create a sense of privacy for the customers. Besides having a practical function, Japanese norens are also meant to add an air of beauty to any space.
