The area of Kumiyama was part of ancient Yamashiro Province. During the Edo Period, the area was part of the direct holdings of the Tokugawa shogunate. The villages of Sayama and Mimaki were established on April 1, 1889 with the creation of the modern municipalities system. The two villages merged on October 1, 1954 to form the town of Kumiyama.

Kumiyama has a mayor-council form of government with a directly elected mayor and a unicameral village council of 14 members. Kumiyama, collectively with the city of Uji, contributes five members to the Kyoto Prefectural Assembly. In terms of national politics, the village is part of the Kyoto 6th district of the lower house of the Diet of Japan.

Kumiyama has a mixed economy. The northern half of the town area is a large rice-growing area called Ogura Pond Reclaimed Fields. To the west of Japan National Route 1, suburban agriculture is thriving. The daikon radish in particular is a regional brand called "Yodo daikon". Because Japan National Route 1 runs through the town, it is possible to quickly ship products to consumption areas. The Kumiyama Industrial Park is located in the area adjacent to the south of Ogura Pond Reclaimed Fields, and there are many establishments mainly involved in metal processing, plastic processing, and food manufacturing. This was the site of the former Kyoto Airfield, which was constructed during World War II, which was converted into an industrial park after the war.

Kumiyama has three public elementary schools and one public junior high school operated by town government, and one public high school operated by the Kyoto Prefectural Board of Education.

Although the Keihan Electric Railway Keihan Main Line passes through the western edge of the town, Kumiyama has no passenger rail service. However, in areas north of the Uji River, Yodo Station is within walking distance. In the southeast, Ōkubo Station and Iseda Station on the Kintetsu Railway's Kyoto Line in the city of Uji
