Kotsuka Station (古津賀駅, Kotsuka-eki) is a train station in Shimanto, Kōchi Prefecture, Japan, operated by the Tosa Kuroshio Railway.

[2] The station is also served by JR Shikoku Ashizuri limited express services from Nakamura and Sukumo to Kōchi, with one train a day (in the direction of Kochi only) stopping at Kotsuka.

The station, which is unmanned, consists of a side platform serving a single track.

A parking area with vending machines and a bike shed is located at the base of the embankment off National Route 56.

A flight of steps leads from this parking area to the platform and the station is thus not wheelchair accessible.
