The entire line between Kobe Station and Shimonoseki Station was originally opened by the private Sanyō Railway company. The section between Hyōgo Station (in Kobe) and Akashi Station (in Akashi, Hyōgo) opened first in 1888. In 1889 the line was extended to the east to Kobe Station (as a dual track section) and Tatsuno Station (in Tatsuno, Hyōgo Prefecture) to the west. The Sanyō Railway was progressively extended to the west, reaching Okayama and then Fukuyama in 1891, Hiroshima in 1894 and in 1901 it reached Bakan (now Shimonoseki) Station. Under the Railway Nationalization Act of 1906 it was purchased by the Japanese government and renamed Sanyō Main Line.

The Hyogo – Himeji section was duplicated in 1899, and the Hiroshima – Kaitaichi section in 1903. After the line was nationalised, further duplications occurred between Kamigori – Yoshinaga in 1910/11, Hatabu – Shimonoseki in 1915 and Himeji – Agaho in 1917. Work to duplicate the remainder of the line commenced in 1921, and opened in stages until completed in 1930, with the exception of the section between Iwakuni and Kushigahama, where construction of a new direct line had commenced. This direct line, which bypassed the coastal section via Yanai involved significant tunnelling, and unexpected geological instability delayed completion of the line until 1934, and then as a single track. Although the new line became the Sanyo Main Line at that time, in 1944 the original coastal alignment was duplicated and returned to the formal Sanyo Main Line, with the former bypass line becoming the Gantoku Line.

The Kobe – Akashi section was electrified in 1934, extended to Himeji in 1958, Hiroshima in 1962 and (except for the Wadamisaki Line, which was electrified in 2001) the entire line was electrified in 1964, to coincide with the opening of the Tōkaidō Shinkansen between Tokyo and Shin-Osaka the same year.

The Sanyō Main Line approximately parallels the Inland Sea but some sections could be shortened by tunnels. In 1934, the Gantoku Line between Iwakuni and Tokuyama was opened and replaced the former line which traverses Yanai adjacent to the Inland Sea. In 1944, this new alignment was replaced again by the previous coastal alignment because the coastal line was upgraded to dual tracks.

The Sanyō Main Line was connected to Kyushu by ferry from Shimonoseki and Shimonosekiko Station (Port Shimonoseki). In 1942, the Kanmon Tunnel under the Kanmon Straits was completed and the Sanyō Main Line was extended to Moji Station. A second tunnel duplicating the section opened in 1944.

Prior to the opening of the San'yō Shinkansen, many expresses operated on the Sanyō Main Line as it served as a major transport corridor through Western Honshu and connecting to Kyushu. The Shinkansen was extended as the San'yō Shinkansen line, first to Okayama Station in 1972, and then to Hakata Station in 1975. On both occasions, many express services on the Sanyo Main Line were withdrawn, and since 1972, the line has been mainly used by local and freight services. CTC signalling was commissioned between Mihara and Shimonoseki in 1984.

The section between Kobe and Nishi Akashi was severely damaged by the 1995 Great Hanshin earthquake, and took ten weeks to repair.

The 2018 Japan floods resulted in the Okayama – Shimonoseki section closing on 6 July 2018.^[2] The majority of services were restored between 8 July – 18 July of that year, but the Yanai – Tokuyama section remained out of service until 9 September of that year.^[3]

The Army leased the line in 1915 for use during WW1 and subsequent hostilities in China, and passenger services were suspended between 1919 and 1930.
