The area of present-day Kurihara was part of ancient Mutsu Province, and has been settled since at least the Jōmon period by the Emishi people. During the later portion of the Heian period, the area was ruled by the Northern Fujiwara. During the Sengoku period, the area was contested by various samurai clans before the area came under the control of the Date clan of Sendai Domain during the Edo period, under the Tokugawa shogunate.

With the establishment of the modern municipalities system on April 1, 1889, the area was organized into Kurihara District, Miyagi Prefecture.

During the Meiji period, many mines were dug in the mountains of Kurihara, and the Hosokura mine was at one point Japan's largest producer of lead and zinc. The mine closed in 1987.

The city of Kurihara was established on April 1, 2005, from the merger of the towns of Ichihasama, Kannari, Kurikoma, Semine, Shiwahime, Takashimizu, Tsukidate, Uguisuzawa and Wakayanagi, and the village of Hanayama (all from Kurihara District, which was dissolved as a result of the merger). The new city hall is located in former Tsukidate. Although technically referred to as a "city", Kurihara in fact functions more like a county composed of ten separate towns. This arrangement is similar to English unitary authorities in the United Kingdom, such as Herefordshire.

During 2011 Tōhoku earthquake, Kurihara–specifically the former town of Tsukidate–experienced the strongest shaking, with a Shindo 7 intensity.

Kurihara has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 26 members. Kurihara contributes two seats to the Miyagi Prefectural legislature. In terms of national politics, the city is part of Miyagi 6th district of the lower house of the Diet of Japan.

The economy of Kurihara is largely based on agriculture. Mining, which once formed a significant percentage of the economy has largely disappeared with the closure of the last mines in the 1980s.

Kurihara has 13 public elementary schools and eight public junior high schools operated by the city government and five public high schools operated by the Miyagi Prefectural Board of Education. The prefecture also operates one special education school for the handicapped.
