A small post town existed in this area since the Heian period, as Oyama is located at the base of the Ashigara Pass on the main route connecting the ancient provinces of Sagami with Kai and Suruga Provinces. The area was mostly tenryō territory under direct control of the Tokugawa shogunate in the Edo period. With the establishment of the modern municipalities system in the early Meiji period on April 1, 1889, the area was reorganized into the villages of Rokugo, Kannuma, Ashigara, Kitago and Subashiri within Suntō District, Shizuoka, two months after the opening of Suruga-Oyama Station on the Tōkaidō Main Line (now Gotemba Line).

The villages of Rokugo and Suganuma merged to form Oyama on August 1, 1912. Oyama annexed neighboring Ashigara on April 1, 1955, Kitago Village on August 1, 1956 and Subashiri on September 30, 1956. The Furusawa District of former Kitago transferred from Oyama to Gotemba on September 1, 1957.


Due to its proximity to the Tokyo metropolitan area, Oyama has a mixed economy of agriculture and light industry. Rice is the principal agricultural crop.


Oyama has five public elementary schools and three public junior high school operated by the town government. The town has one public high school operated by the Shizuoka Prefectural Board of Education.
