Noren are traditional Japanese fabric dividers, hung between rooms, on walls, in doorways, or in windows. They usually have one or more vertical slits cut from the bottom to nearly the top of the fabric, allowing for easier passage or viewing. Noren are rectangular and come in many different materials, sizes, colors, and patterns. Exterior noren are traditionally used by shops and restaurants as a means of protection from sun, wind, and dust, and for display of shop name or logo.
