Ryōseki-dōri Station opened on 4 December 1910, when Tosa Electric Railway (土佐電気鉄道) extended the future Gomen Line from Kako Station to a now-vanished terminus called Ōtsu just 0.4 km east of here. That Ōtsu stop opened the same day; the line was pushed on to Gomen-nakamachi-dōri seven weeks later in January 1911, and Ōtsu was discontinued sometime after 1912. A turnout was added on 1 November 1984, and in 2003 the tracks here were re-aligned during embankment work on the Funairi River — the platforms reaching their present positions on 21 June and 5 July 2003. The stop passed to Tosaden Kōtsū on 1 October 2014 after the operator merger. The stop is sometimes signed as "Ōtsu Ryōseki-dōri."

The name Ryōseki refers to a place at the foot of the Nebiki Pass in Nankoku, reached by an old highway running north from the stop. A now-vanished stop called Ōtsu once stood 0.4 km east of here and was the line's terminus when it opened in December 1910.
