• JR Hanwa Line: Yamanakadani ⇄ Musota

Kii opened on 16 June 1930 when the Hanwa Electric Railway extended its line from Izumi-Fuchū to Hanwa-Higashi-Wakayama (now Wakayama). It became a Nankai Yamate Line station when Nankai absorbed Hanwa on 1 December 1940, and was nationalised on 1 May 1944, joining the Ministry of Transport and Communications' Hanwa Line. The 1987 break-up of Japanese National Railways transferred operation to JR West. Selected morning and evening rapid services began stopping there on 13 March 1988, and Kii became an all-day rapid stop when the Kishūji Rapid service began on 10 May 1999. ICOCA contactless ticketing was introduced on 1 November 2003, and the staffed Midori-no-Madoguchi closed on 18 March 2022. The station carries the line code JR-R51.

Because the line climbs over the Onoyama Pass through the Izumi Mountains, the 8.1-km gap between Kii and its northern neighbour Yamanaka-Dani is the longest inter-station distance on the Hanwa Line.
