Iha Fuyū (伊波 普猷; March 15, 1876 – August 13, 1947) is considered the father of Okinawaology and was a Japanese scholar who studied various aspects of Japanese and Okinawan culture, customs, linguistics, and folklore. He signed his name as Ifa Fuyu in English, because of the Okinawan pronunciation. Iha studied linguistics at the University of Tokyo and was devoted to the study of Okinawan linguistics, folklore, and history. His most well-known work, Ko Ryūkyū (Ancient Ryūkyū), was published in 1911 and remains one of the best works on Okinawan studies. He devoted much time to uncovering the origins of the Okinawan people to establish their history. He had considerable influence not only on the study of Okinawan folklore but also on Japanese folklore.
