History
Musashi-Mizonokuchi Station opened on 9 March 1927 as a station on the Nambu Railway's Kawasaki - Noborito section, in Kawasaki, Kanagawa Prefecture. The Nambu Railway was nationalized on 1 April 1944, becoming part of the Japanese Government Railway and later Japanese National Railways (JNR). Freight services were discontinued on 1 March 1976, and a Midori-no-Madoguchi staffed ticket office opened on 1 July 1976. Following the privatization of JNR on 1 April 1987, the station came under JR East. Automatic ticket gates were installed at the permanent ticket gate on 2 November 1993, and the station building was rebuilt as an elevated station with a north-south pedestrian passageway on 9 August 1998. Suica IC card use began on 18 November 2001. Following the post-Tōhoku-earthquake reschedule, the station became a Nambu Line Rapid stop on 9 April 2011. The station became JR East's sixth "Eco Station" demonstration site on 17 April 2017. Platform doors were installed on platforms 1 and 2 on 19 April 2024, and smart platform doors on platform 3 on 24 December 2024.

Notes
From 1 July 2024 to 14 March 2025, JR East used Ayaka Hirahara's debut song "Jupiter" as the station's departure melody, marking the centenary of both Kawasaki City and the Senzoku Gakuen — both of which are tied to Hirahara, who studied at the Senzoku Gakuen College of Music. Hirahara arranged and performed the melody herself and served as the station's stationmaster for a day at the launch event.
