• JR Hanwa Line: Kumeda ⇄ Higashi-Kishiwada

Shimomatsu opened on 1 April 1984 between Kumeda and Higashi-Kishiwada on the Japanese National Railways' Hanwa Line. The City of Kishiwada bore the full 700-million-yen construction cost, and the resulting petitioned station is the most recently opened on the entire Hanwa Line — no new station has been added there since. The 1987 break-up of JNR transferred operation to JR West. Automatic ticket gates went in on 4 June 1998 and ICOCA contactless ticketing followed on 1 November 2003. The Midori-no-Madoguchi ticket office closed on 28 July 2016, replaced the next day by a Midori-no-Kenbaiki Plus self-service machine. Station code JR-R39 was assigned on 17 March 2018, and the Plus machine itself was removed on 23 August 2024.

To distinguish this station from Kudamatsu on the San'yō Main Line in Yamaguchi Prefecture, tickets are stamped '(Han) Shimomatsu' and ICOCA logs show it as 'Shimomatsu' in katakana.
