Tsunashima Station opened on 14 February 1926 as Tsunashima-Onsen Station, named for the hot-spring resort the operator hoped to develop. It was rebuilt as an island-platform stop in July 1933 and renamed Tsunashima on 20 October 1944, with wartime regulations dropping the "Onsen" suffix as resort closures stripped the original meaning. Elevation works begun in March 1962 ended on 26 November 1963 with a new 700-metre viaduct that removed three level crossings at a cost of 377 million yen. The station building was refurbished in 2001 with a new north exit and see-through gates, and platforms were extended in 2012 to handle ten-car Fukutoshin-Line through trains. The retail complex Etomo Tsunashima below the viaduct opened on 13 March 2020 (TY14).

The 2.2 km gap to the neighbouring Hiyoshi Station is the longest interstation distance on the entire Tōyoko Line.
