According to Japanese census data, the population of Inagi has increased steadily since the 1950s.

The area of Inagi has been settled since the Japanese Paleolithic, or for over 20,000 years, based on projectile points, stone tools and microliths found in several locations within city borders. There is evidence of several Jomon period settlements, but settlement disappeared towards the end of the Jomon period due to climate change and eruptions of Mount Fuji. The area was sparsely settled in the Yayoi period, with increasing settlement density in the Kofun period. A number of Nara period remains have been found, including the ruins of a roof tile kiln. During the Heian period, the area became part of a shōen controlled by the Oyamada clan, and later by their cadet branch, the Inabe clan into the Kamakura period, and was an area contested between competing branches of the Ashikaga clan and Uesugi clan in the Muromachi and Sengoku periods. After the start of the Edo period, the area was tenryō controlled directly by the Tokugawa shogunate. Inagi Village was established on April 1, 1889, in Minamitama District, Kanagawa Prefecture, through the merger of the villages of Yanokuchi, Higashi-Naganuma, Omaru, Momura, Sakahama and Hirao under the modern municipalities system. Minamitama District was transferred from Kanagawa Prefecture to Tokyo Prefecture in 1893. Parts of Oshitate and Tokihisa were incorporated into Inagi Village in 1949. Inagi was elevated to town status on April 1, 1957, and became a city on November 1, 1971. From the latter half of the 20th century, the development of Tama New Town contributed to its transformation from an agricultural community into a suburban residential city.

Inagi has a mayor-council form of government with a directly elected mayor and a unicameral city council consisting of 22 members. For the Tokyo Metropolitan Assembly, Inagi forms an electoral district together with the city of Tama, which elects two members. For the House of Representatives of the National Diet, Inagi is part of the Tokyo 30th district.

Inagi is primarily a bedroom community for central Tokyo, with large-scale residential development associated with the Tama New Town project from the 1960s onward. Agriculture remains important in some areas, particularly the cultivation of Japanese pears and grapes. The city is also home to manufacturing and technology companies, including paper machinery manufacturer Nippon Filcon, electronic musical instrument manufacturer Korg, and Fujitsu Frontech. Tourism and leisure also contribute to the local economy through facilities such as Yomiuriland and TOKYO GIANTS TOWN.

Higher education institutions in the city include Komazawa Women's University and Komazawa Women's Junior College. The Tokyo Metropolitan Government Board of Education operates Tokyo Metropolitan Wakaba Comprehensive High School. The city also contains the private Komazawa Gakuen Girls' Junior High School and Senior High School. Inagi has twelve public elementary schools and six public junior high schools operated by the Inagi City Board of Education.
