The area of present-day Isehara City was part of several large shōen in Sagami Province during the Kamakura period. During the Edo period, it was nominally part of Odawara Domain, although large portions were tenryō territory controlled by the shōgun in Edo through various hatamoto.

After the Meiji Restoration and with the establishment of the district system in 1878, the area came under the control of Ōsumi District (大住郡, Ōsumi-gun), Kanagawa Prefecture and became Isehara Town on April 1, 1889 with the establishment of the modern municipalities system. On March 26, 1896, Ōsumi District and Yurugi District were merged to create Naka District. The town began to experience rapid growth after the opening of Isehara Station on the Odakyu Electric Railway on April 1, 1929. On December 21, 1954, the town expanded through merger with neighboring Oyama Town and three villages. Its area expanded further on September 30, 1956, through annexation of a portion of neighboring Okazaki Village. Isehara was elevated to city status on March 1, 1971.


Isehara has a mayor-council form of government with a directly elected mayor and a unicameral city council of 20 members. Isehara contributes one member to the Kanagawa Prefectural Assembly. In terms of national politics, the city is part of Kanagawa 16th district of the lower house of the Diet of Japan.


Known primarily as a bedroom community for Yokohama and the greater Tokyo area, Isehara is also home to Amada Co, a machine tool manufacturer and a number of manufacturing plants. It is also home to a Maru-Chan (Toyo Suisan) instant noodle factory.


Isehara has ten public elementary schools and four public middle schools operated by the city government. The city has two public high schools operated by the Kanagawa Prefectural Board of Education, and the prefecture also operates one special education school for the handicapped. There is also one private high school. Tokyo-based Senshu University, Sanno University and Tokai University all have a campus within Isehara.
