History
Kaina Station opened on 18 December 1963 as an unstaffed intermediate stop when Japanese National Railways completed the Nakamura Line between Kubokawa and Tosa-Saga. With the 1987 privatisation of JNR, control passed briefly to JR Shikoku, before transferring on 1 April 1988 to the newly-formed third-sector Tosa Kuroshio Railway as part of the Nakamura Line's conversion. The station consists of a single side platform on a hillside cutting in what is now the town of Kuroshio, Kōchi. There is no station building, only a platform shelter, toilet, and bike rack. The Nakamura Line's spiral loop section is located near the station.
