Hakata ori refers to the ori or woven cloth produced in and around Hakata, Fukuoka prefecture. Hakata weaving techniques, which originated in China, have shaped this unique cloth. It is characterized by a tightly woven texture that is attained by using a number of thin warps (perpendicular threads) that are strongly drawn by thick wefts which raise the warps to the surface into a pattern. With excellent tightness, thickness, and durability, Hakata brocade was sought after as Japanese kimono sashes for men called obi, sashes for samurai in ancient times, and loincloths for sumo wrestlers in recent years. A silk rustling sound known as kinunari in Japanese is produced when a kimono sash is tightened, which is unique to Hakata ori.
