Noren are traditional Japanese fabric dividers, hung between rooms, on walls, in doorways, or in windows. They are also used at shops to indicate that the business is open and as room dividers. 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. Noren most commonly come down to neck or chest height but some go down all the way to the ground.
