Minami-Hashimoto Station was opened on November 1, 1932, as Okawara Siding (大河原停留場, Okawara teiryūjō), a rail siding on the Sagami Railway. It was renamed Sagamimachi Siding (相模町停留場, Sagamimachi teiryūjō) in 1940. On April 1, 1941, it was elevated in status to a Sagamimachi Station (相模町駅, Sagamimachi-eki). On June 1, 1944, the Sagami Railway was nationalized and merged with the Japanese Government Railways, at which time the station received its current name. On April 1, 1987, with the dissolution and privatization of the Japanese National Railways, the station came under the operation of JR East. Scheduled freight services were discontinued from 1996. Automated turnstiles using the SuicaIC card system came into operation from November 2001. The station building was complexly rebuilt in 2006.
