History
Ōtaguchi Station opened on 28 October 1934 as an intermediate stop on what was then the Kōchi Line, operated by Japanese Government Railways. Located in the town of Ōtoyo in Kōchi Prefecture's Nagaoka District, the station sits 80.4 km from the Dosan Line's starting point at Tadotsu. The track curves through the station, so limited-express trains slow as they pass through. After successive transitions to Japanese National Railways and, upon the 1987 privatisation, to JR Shikoku, Ōtaguchi today operates as an unstaffed island-platform stop with a single passing siding, carrying the station number D30.

Notes
The station name comes from the sangō (honorific mountain title) of nearby Buryaku-ji temple, '大田山' (Ōtazan), whose Yakushi-dō hall is designated a National Treasure of Japan.
