Nobori
History of use. The "nobori" were significant on the battlefields of feudal Japan. The "nobori" of the time were used to denote units within an army; "nobori" became much more common in the Sengoku period, in use alongside the earlier "hata-jirushi". Though usually used to represent different divisions within an army, "nobori" were sometimes made identical, so as to produce an impressive and intimidating display of warrior flags. Today "nobori" are a common sight outside businesses, restaurants, and retail stores where they advertise a sale, a new product, and simply the name of the business. They are used  during festivals and sports events; in sports they take the place of the banners and signs common among Western audiences. They are also used to make commercial announcements, appeal for something, and identify a political party during an election campaign. They may also line the walkways, fences or walls of Shinto shrines or Buddhist temples and frequently bear the names of donors or deceased parishioners. In recent years, "nobori" influenced flags are gaining popularity around the world.
