Arii Station opened on 8 August 1940 as a station on the Japanese Government Railways Kisei-Nishi Line, built during the extension from Shingū to Kii-Kimoto (today's Kumanoshi). The line was reorganised as part of the Kisei Main Line on 15 July 1959 once the through route from Kameyama to Wakayama was completed. Freight handling was withdrawn in 1962, and the station became unstaffed on 21 December 1983 when parcel service also ended. With the privatisation of Japanese National Railways on 1 April 1987, control passed to JR Central. The original wooden station building has since been demolished and replaced by a trapezoidal prefabricated shelter, and the station has no ticket vending machine and no boarding-station certificate machine.

The station name combines the old place names Arima and Ido, the village of Arii having taken its identity from this fusion before the area was absorbed into Kumano City.
