History
Kagaonsen Station opened on 11 October 1944 as Sakumi Station (作見駅), the wartime promotion of a 1943 signal stop on the Hokuriku Main Line. It was renamed on 1 October 1970 after a fierce dispute among the Katayamazu, Yamashiro and Yamanaka onsen communities over which station the new Hakuchō limited expresses would call at; the JNR settled the contest by consolidating express stops at this midpoint station and rebranding it as the gateway to the Kaga onsen district. With the 1987 privatisation it became part of JR West. On 16 March 2024 the Hokuriku Shinkansen's Kanazawa–Tsuruga extension opened, adding a Shinkansen platform here while the conventional line transferred to IR Ishikawa Railway.

Notes
Despite the name, no onsen of that name exists in the vicinity; the station serves as a transfer hub for buses to the actually-named Yamanaka, Yamashiro and Katayamazu hot-spring resorts.
