Chōyō Station opened on 12 February 1928 as a Ministry of Railways station. It was placed under contracted operation on 1 September 1961, freight handling ended on 1 October that year, and it became unstaffed when baggage handling ended on 20 February 1971. On 1 April 1986 the line was converted from Japanese National Railways' Takamori Line to the third-sector Minami-Aso Railway; service was suspended after the Kumamoto earthquakes of 14 and 16 April 2016 damaged bridges and tunnel structures on the line, and full service resumed on 15 July 2023 when the Tateno–Nakamatsu section was restored. It is a ground-level station with one side platform serving one track, and although unstaffed it retains its wooden station building.

Minami-Aso has short hours of sunshine because of the surrounding caldera rim, but since the rim is broken at Tateno, this area receives long hours of afternoon western sun, which is the origin of the name "Chōyō" (long sun). The section that was once the station office has been converted into the café "Hisanagaya," which is open only on Saturdays and Sundays.
