Tosu Station opened on 11 December 1889 as one of the original stops on the privately-run Kyushu Railway when it linked Hakata with Chitosegawa. A line to Saga followed on 20 August 1891, establishing the junction with what became the Nagasaki Main Line. The station was nationalised on 1 July 1907 and joined the Kagoshima Main Line in 1909. The current wooden station building was constructed in July 1903 and enlarged in 1911. From 1925 to 1984 the adjacent Tosu marshalling yard handled a large share of Kyushu's rail freight, with around 700 staff working a 420,000-square-metre site. JR Kyushu took over at privatisation in 1987 and SUGOCA IC service began on 1 March 2009.

The pillars on platform 5 are painted blue, red and green — colors that corresponded to the "Kamome", "Huis Ten Bosch" and "Midori" portions of the triple-decker limited express running when the pillars were painted, a train that was divided at Hizen-Yamaguchi and Haiki.
