• JR Nippo Line: Takarabe ⇄ Nishi-Miyakonojo

Isoichi Station was opened on 28 April 1929 by Japanese Government Railways as an intermediate stop on the new Kokuto East Line. By December 1932 the route had been joined to networks to the north and south, and the entire stretch from Kokura to Kagoshima via Isoichi was redesignated as the Nippō Main Line. Freight handling ended in September 1962 and baggage handling in October 1979, when the station also became unstaffed. The 1993 floods cut the line between Nishi-Miyakonojō and Kagoshima for several weeks. JR Kyushu took over on 1 April 1987, and the station was reassigned from the Kagoshima branch to the new Miyazaki branch in April 2022.

Before the Second World War the station stood next to the Imperial Japanese Army's 23rd Infantry Regiment garrison, giving the site military as well as civilian importance.
