Uzen-Nagasaki Station began operation on July 20, 1921. The station briefly acted as the terminal station of the Aterazawa line, until December 11, 1921, when the line was extended to Sagae. With the privatization of the JNR on April 1, 1987, the station came under the control of the East Japan Railway Company. In 2004, platform 1 of the island platform was transformed into a west-side exit at the request of residents on the west side of the station.

The Station will start accepting Suica Cards in Spring 2024, with the extension of the Sendai area Suica zone to Yamagata Prefecture.
