• Ainokaze Toyama Railway Line: Etchu-Daimon ⇄ Kureha

Kosugi Station opened on 20 March 1899 as a general station of the state-built Hokuriku Line, when the Takaoka–Toyama section was extended, at Sanga in Kosugi-machi, Imizu-gun. The 12 October 1909 route-name decree placed it on the Hokuriku Main Line, and the Kanazawa–Toyama freight yard section was electrified with alternating current in August 1964. The station passed to JR West and JR Freight at the 1 April 1987 privatisation, and a dedicated ticket office (Midori-no-madoguchi) opened in March 1989. During the JR West era a number of limited-express services — Thunderbird, Shirasagi, Hokuetsu and Hakutaka — stopped here. A south entrance was added on 20 December 1996 to align with the opening of the al·Plaza Kosugi shopping centre, and on 14 March 2015, with the opening of the Hokuriku Shinkansen to Kanazawa, the station was transferred to the Ainokaze Toyama Railway.

On 7 July 1990 the stationmasters of Kosugi and Komatsu signed a sister-station agreement at JR West's Kanazawa Branch headquarters, formally pairing the two Hokuriku Main Line stops.
