History
Okoba Station opened on 26 December 1909 as part of the then-Kagoshima Main Line, established by the Imperial Railway Agency. The hilltop site, far from any settlement, was chosen to serve steam locomotives climbing the grade from Hitoyoshi: trains stopped here for water, and the spiral plus switchback alignment provided a level platform on the steep climb to Yatake. With the coastal route completed on 17 October 1927, the inland line was redesignated as the Hisatsu Line and Okoba was reassigned to it. Freight ended in 1974, baggage in 1984, and the station became unstaffed in 1986. JR Kyushu inherited it in 1987, and in 2007 the station was designated industrial heritage.

Notes
Okoba is the only station in Japan to combine a spiral (loop) line with a switchback; the surrounding masonry water tower and "morning-glory" fountain were designated industrial heritage in 2007.
