• JR Nambu Line Hamakawasaki Branch: Inagi-Naganuma ⇄ Inadazutsumi

Yanokuchi Station opened on 1 November 1927 when the Nambu Railway extended west from Noborito to Ōmaru in present-day Inagi, on the southern fringe of Tokyo. The line was nationalised on 1 April 1944 and the station passed to JR East at privatisation on 1 April 1987. Automated fare gates entered service on 17 September 1993 and Suica IC cards followed on 18 November 2001. A grade-separation project lifted the down platform onto a viaduct on 25 July 2004 and the up platform on 9 October 2005, eliminating an adjacent level crossing on the Tsurukawa Highway. The Midori-no-Madoguchi ticket office closed on 30 October 2016 and smart platform-edge doors entered service on 25 November 2023.

Yanokuchi is the southernmost JR East station inside the boundary of Tokyo Metropolis on the Nambu Line, and from here onwards the line's Tokyo segment is administered by the company's Hachiōji Branch.
