The Hayato (隼人?), literally meaning "falcon-men", were a people of ancient Japan who lived in the Satsuma and Ōsumi regions of southern Kyushu until at least the Nara period. Due to the distinct nature of their manners and customs, they frequently resisted Yamato rule. After their subjugation they became subjects of the government under Ritsuryō, and the Ministry of the Military had an office known as the Hayato-shi (隼人司?) in charge of their governance. The name also came into use by samurai as a title, hayato no suke (隼人助?). In modern times, Hayato is a Japanese male given name.
The Hayato may be the same as the Kumaso group of around the same time, but while the Kumaso are mentioned in the more legendary portions of the Nihon Shoki, the Hayato are recorded in various historical texts until the beginning of the Heian period. Though the Kumaso are generally portrayed as rebellious, Hayato are listed among the attendants of emperors and princes from as early as Emperor Nintoku's reign. This, along with a mention of Hayato crying before the grave of Emperor Yūryaku after his death, suggests that the Hayato were naturalized as personal servants by the late 7th century.
