Since the Meiji Restoration, what is now called Motoyama town has gone through several territorial changes. In 1889, 12 villages combined to become what was called Nishimotoyama Village, which was renamed as Motoyama Village a year later. In 1910 the village was reclassified as a "town." Also in 1889, 13 other villages neighboring Motoyama combined to become Yoshino Village. It was in 1955 when Motoyama and Yoshino villages combined, but soon after that 5 western wards were separated and were incorporated into the neighboring Tosa.
