Chōshi Station opened on 1 June 1897 as the eastern terminus of the Sōbu Railway, 120.5 km from Tokyo. The Sōbu Railway was nationalised on 1 September 1907 and the station passed to JR East at privatisation on 1 April 1987. On 5 July 1923 the privately operated Chōshi Electric Railway Line opened eastward to Tokawa, reusing the trackbed and infrastructure left by the short-lived Chōshi Sightseeing Railway of 1913–1917. The 1936 two-storey wood-frame-and-mortar station building was destroyed by fire in 1945 during the Second World War, and the third-generation building was completed in January 1948. Scheduled freight ceased on 31 March 1978.

The entrance to the Chōshi Electric Railway's bay platform, set between JR platforms 2 and 3, is sheltered by a Dutch-style structure erected in November 1990, which replaced a roof added there in December 1974.
