History
Yamamoto Station opened on 1 December 1898 as a station of the private Karatsu Kōgyō Railway, predecessor of today's Karatsu Line. The freight-only Kishidake branch of the Karatsu Line opened from here on 17 January 1912 and added passenger service on 21 September 1912. On 1 April 1929 the North Kyushu Railway (predecessor of the Chikuhi Line) reached Yamamoto from Higashi-Karatsu, making it an interchange between the Railway Ministry and a private operator. On 1 March 1935 the North Kyushu line was completed through to Imari, and on 1 October 1937 North Kyushu was nationalised as the Chikuhi Line. The Kishidake branch was abolished on 20 August 1971. The Chikuhi Line was restructured on 22 March 1983: the new Niji-no-Matsubara - Wadata - Karatsu route opened and the old Niji-no-Matsubara - Kuri - Yamamoto stretch closed, also shifting station operations to a contracted basis. Yamamoto was destaffed on 20 January 1985, and on 1 April 1987 with the JNR breakup the station became JR Kyushu — at which time it also became the eastern terminus of the western Chikuhi Line section.

Notes
Yamamoto was once the only transfer station between the Karatsu Line and the Chikuhi Line, and it was the starting point for the Kishidake branch of the Karatsu Line — at peak it had five lines fanning out in five directions and was a thriving interchange where the Express "Hirado" stopped. The 1971 closure of the Kishidake branch and the 1983 Chikuhi Line restructuring (which routed the Chikuhi - Hakata/Meinohama traffic via Karatsu Station instead of Yamamoto) drained away its transfer role, and today it is a quiet intermediate stop.
