The area of present-day Daisen was part of ancient Dewa Province. During the Edo period, the area came under the control of the Satake clan, who had been relocated to Kubota Domain from their former holdings in Hitachi Province. After the start of the Meiji period, and the establishment of the modern municipalities system, the area became part of Semboku District, Akita Prefecture in 1878.[5]

The city of Daisen was established on March 22, 2005, from the merger of the city of Ōmagari, the towns of Kamioka, Kyōwa, Nakasen, Nishisenboku, Ōta and Semboku, and the village of Nangai (all from Semboku District).[5]

The city contributes five members to the Akita Prefectural Assembly. In terms of national politics, the city is part of Akita 3rd District of the lower house of the Diet of Japan.
