The town of Gosen was created within Kitakanbara District, Niigata with the establishment of the modern municipalities system on April 1, 1889. The modern city of Gosen was established on November 3, 1954, from the merger of the town of Gosen with the village of Sumoto, Kawahigashi and Hashida (all from Kitakanbara District). On January 1, 2006, the town of Muramatsu (from Nakakanbara District) was merged into Gosen.
