• Kisei Line: Kii-Shinjo ⇄ Shirahama

Asso Station opened on 20 December 1933 as part of the Japanese Government Railways' Kisei West Line, on its extension from Kii-Tanabe toward Kii-Tomida. The station building was rebuilt in June 1948 after war damage, and the surrounding line became part of the Kisei Main Line on 15 July 1959 when the Kisei route was unified. Freight handling ended in January 1986 and the station was destaffed that March. With the privatisation of Japanese National Railways on 1 April 1987 it passed to JR West, and ICOCA acceptance began on 13 March 2021. The single island-platform structure remains the only railway station within Kamitonda, Wakayama Prefecture.

Locals know Asso as one of the Kinokuni Line's three notoriously hard-to-read station names, alongside Shimizu-ura and Haya.
