• Nagasaki Main Line: Nakabaru ⇄ Kanzaki (Saga)

The station opened on 30 September 1942 as Mitagawa Signal Box on the Japanese Government Railways Nagasaki Main Line, becoming Mitagawa Station for passenger service on 1 December 1943. Station management was outsourced from 5 March 1974, freight ended on 19 February 1976 and parcel handling ended on 1 February 1984, before the station became unstaffed on 20 January 1985. JR Kyushu took over on 1 April 1987 with privatisation. Following the late-1980s excavations of the nearby Yoshinogari archaeological site, the station was renamed Yoshinogari-Kōen on 1 October 1993 to advertise the historical park, and a new overhead-bridge station building opened on 1 March 2000. SUGOCA service began on 1 March 2009, and from the 12 March 2011 timetable revision one daily round of the Midori and Huis Ten Bosch limited express services began stopping here to serve park tourists.

JR Kyushu uses both spellings of the station's name in its official materials: 吉野ケ里公園駅 with the katakana ケ and 吉野ヶ里公園駅 with the small ヶ both appear on its website and in its publications.
