The area of present-day Shōnai was part of ancient Dewa Province. After the start of the Meiji period, the area became part of Higashitagawa District, Yamagata Prefecture. The town of Amarume was established on April 1, 1889, with the creation of the modern municipalities system, and the town of Karikawa on April 1, 1937. Karikawa merged with the neighboring villages of Kiyokawa and Tachiyazawa on October 1, 1954, and was renamed Tachikawa. On July 1, 2005, the towns of Tachikawa and Amarume merged to form the new town of Shōnai. [citation needed]
The economy of Shōnai is based on agriculture.
Shōnai has five public elementary schools and two public middle schools operated by the town government, and one public high school operated by the Yamagata Prefectural Board of Education.
