sudare

Sudare (簾) is a traditional Japanese window blind consisting of thin, woven bamboo or reed slats suspended by horizontal threads. The slats form a semi-transparent screen that can be extended to shade a room while allowing air to circulate. Sudare are commonly hung from eaves, window frames, or ceilings and can be rolled up or removed when not in use. They reduce direct sunlight, cool interiors in summer, and provide privacy without completely blocking light. Because the material is porous, air can pass through, making sudare effective for natural ventilation. Modern recreations may use stronger or lighter weaves or synthetic fibers, but the traditional design remains focused on light diffusion and ventilation. A typical sudare consists of narrow bamboo slats or interwoven reeds connected by vertical threads, with a top header or cord system to raise or lower and a bottom weight to keep it taut. Some designs include decorative tassels or patterned weaving.

Sudare have a long history in East Asia, particularly Japan, where they became common in Edo-period homes and tea houses. They are associated with seasonal summer aesthetics and are used in traditional architecture as well as contemporary interiors seeking a natural, light-filtering element.

Care and maintenance involves keeping the blinds dry to prevent mold; cleaning is usually done with a soft brush or cloth, and if stained they may be lightly washed and air-dried, avoiding soaking the wooden slats.
