• Kikuchi Line: Kitakumamoto ⇄ Uchigoshi

Tsuboigawa-kōen Station opened on 9 January 1995 on the Kikuchi Line of Kumamoto Electric Railway, a private operator, and is located in Chūō-ku of Kumamoto City. The stop was built to serve the new Tsuboigawa Flood Control Park and Tsuboigawa Green Space that were under development at the time, and only local trains call there. The station sits 2.6 km from Kami-Kumamoto, the starting point of the line, and consists of a single side platform at grade with no station building, an unattended stop equipped with an entry-side IC card reader after the operator adopted the regional Kumamon IC CARD on 1 April 2015. Station numbering KD05 was introduced on 1 October 2019.

Although named for an adjacent flood-control park, the station's nearest cultural draw is the prefecturally designated Inariyama Kofun, a tumulus that sits a short walk from the platform.
