Ubara Station opened on 1 April 1927 on the Sotobō Line in what is now the city of Katsuura, Chiba Prefecture. Freight handling was withdrawn in November 1961. After the privatisation of Japanese National Railways on 1 April 1987 it passed to JR East. From 1990 it was operated under a kan'i itaku (simplified-commission) arrangement, and from February 2017 the over-the-counter window closed and the station became fully unstaffed. Suica IC-card service was introduced on 14 March 2009.

Under a 2025 cooperation agreement between JR East and Japan Post, the Katsuura-Ubara post office moved onto the station grounds on 16 June 2025 and was renamed Ubara Station Post Office; its staff now handle fare adjustment and passenger information for the station during the post office's weekday counter hours.
