History
Tosa-Nagaoka Station opened on 1 May 1952 as a new station inserted between Yamada-Nishimachi and Gomen on the existing Dosan Line, when the line was operated by Japanese National Railways. It is situated 114.1 km from the Tadotsu starting point of the line, in the city of Nankoku, Kōchi Prefecture. With the privatisation of JNR on 1 April 1987, control of the station passed to JR Shikoku, which assigned it the station code "D39". The station is an unstaffed single-platform halt with no station building, just a short shelter on a narrow platform; the area surrounding it is mostly paddy fields stretched along National Route 195. One morning up-bound train passes through without stopping.

Notes
The platform speakers do not announce train approaches — they exist solely to broadcast delay notices.
