The membrane structure is a new technology in the fields such as architecture. It is used to form membrane structure buildings that use membrane (fabric) material for roofs and/or exterior walls, or structures that employ membrane interior/exterior parts, such as membrane ceiling.
　Since membrane structures enable various constructions of buildings, they produce a rich spatial design and environment, and exhibit attractive material feeling, taking advantage of the characteristics of the membrane materials that are very different from other building materials.
　The use of membrane structures has been established in wide range of application, including: sports facilities (such as Tokyo Dome, soccer stadiums, athletic stadiums, gymnasiums, and swimming pools), facilities that envelop people’s interaction space in a warm hug (such as Tokyo Station Yaesu GRANROOF, station squares, atriums, and park facilities), traffic space facilities (such as platform roofs and arcade canopies), buildings that contribute development of industry (warehouses, workshops, and factories), education/welfare/medical facilities, stores, and residences that utilize the advantage of the characteristics of the membrane materials and material feelings, membrane ceilings, and other applications that contribute to reduce environmental burdens.
　As the places for community activities and everyday life in all corners of the country, or as regional symbols, membrane structures are expected to contribute to the society. Membrane structures are evolving to foster space creation culture.
