Hachihonmatsu Station was opened on 4 April 1895. It is located in the northwest of the Saijō Basin and is surrounded by mountains. The area around the station is the uppermost part of the Seno River system, which flows to Hiroshima City, but it turns into the Kurose River system, which flows to Kure in the east, with the watershed near the Kamigumi district on the east side. Mountainside alluvial fans have also been cleared, and many terraced rice fields can be seen. Before World War II, the main settlement was located only on the north side of the railroad tracks, in the Kamigumi area on the north and northeast sides of the station, and on the south side of the station, there were almost no houses and it was all paddy fields. On the northwest side of the station was the Imperial Japanese Army's Kawakami Ammunition Depot, which has been managed by the U.S. Forces in Japan after the war. Since the 1960s, the mountains northeast of the station have been cleared to create an industrial park, and much of the paddy fields were reclaimed and converted into a commuter town for Hiroshima and Mihara. Since development progressed mainly on the south side of the station, in 1968 a new station building was built on the overpass directly above the tracks to improve access to the south side, and the station building on the north side was closed. The villages on the north side of the station are lined up along Prefectural Route 46. The section near the station on Prefectural Route 46 was the former Sanyōdō highway in the Edo period.

With the privatization of the Japanese National Railways (JNR) on 1 April 1987, the station came under the control of JR West.

In the 2019 fiscal year, the station was used by an average of 3883 passengers daily.
