As with all of Kōchi Prefecture, the area of Motoyama 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 village of Nishi-Motoyama was established with the creation of the modern municipalities system on October 1, 1889 out of 12 smaller hamlets. It was renamed Motoyama Village on June 1, 1890. Motoyama was raised to town status on June 1, 1910. On April 20, 1955, Motomachi merged with the neighboring town of Yoshino. However, on April 1, 1961, five western hamlets of Motomachi were transferred to the neighboring town of Tosa.

Motoyama has a mayor-council form of government with a directly elected mayor and a unicameral town council of ten members. Motoyama, together with the other municipalities of Tosa District and Nagaoka District, contributes one member to the Kōchi Prefectural Assembly. In terms of national politics, the village is part of Kōchi 1st district of the lower house of the Diet of Japan.
