History
The station opened on 1 August 1927 as Echigo-Tomaru Station of the privately owned Iiyama Railway, serving the Tomaru district of what is now Tsunan town, Niigata. The Iiyama Line was nationalised on 1 June 1944, bringing the station under the wartime Ministry of Transport. Renamed Tsunan on 1 October 1968 to match the surrounding town's name, the station shed freight in 1982 and baggage in 1984. Upon the 1987 privatisation of JNR it joined JR East. On 28 April 1995 the station building was rebuilt jointly with the Riverside Tsunan hot-spring facility — its second storey houses a public bath — and ticket sales today are handled from the onsen front desk under a simplified-agent arrangement.

Notes
Following the 1995 rebuild, Tsunan Station shares a building with the Riverside Tsunan hot-spring complex — the second-floor public bath is open daily except Mondays, and the ticket counter doubles as the onsen reception.
