As with all of Kōchi Prefecture, the area of Ōtoyo was part of ancient Tosa Province. During the Edo period, the area was part of the holdings of Tosa Domain ruled by the Yamauchi clan from their seat at Kōchi Castle. The area was organized into villages within Nagaoka District with the creation of the modern municipalities system on April 1, 1889, including Higashitoyonaga, Nishitoyonaga, Ōsugi, and Tentsubo. These four villages merged on March 31, 1955 to form the village of Ōtoyo. The name Ōtoyo came from taking the Ō (大) in Ōsugi (大杉, Ōsugi) and the Toyo (豊, Toyo) in Toyonaga (豊永, Toyonaga). Following this, a section of Ōtoyo was absorbed into the town of Tosayamada (present day Kami, Kōchi). On the April 1, 1972, the village became a town.
