Mizonokuchi Station opened on 15 July 1927 as a station on the Tamagawa Electric Railway's Mizo-no-kuchi Line, written in Japanese with the katakana "no" (溝ノ口駅) and placed beside the existing Nambu Railway station. The line was regauged in July 1943 and absorbed into the Ōimachi Line. With the line's extension to Nagatsuta the station was elevated on 20 January 1966 and at the same time its Japanese spelling was changed to the hiragana form used today. A major rebuild began in January 1989 and the fourth track entered service on 11 September 1992, leaving the station with two platforms and three tracks in use; the present two-island, four-track elevated layout followed the quadruple-tracking of the Den-en-toshi Line, with the down platform switched to track 1 in July 2008, the up platform to track 4 in June 2009 and Ōimachi Line trains running through to Mizonokuchi from 11 July 2009. Platform doors on tracks 1 and 4 began operation on 10 December 2017.

Mizonokuchi shares its setting with the adjacent JR East Musashi-Mizonokuchi Station on the Nambu Line; the two are connected by the pedestrian deck "Kirari Deck," which lets passengers move between the Tokyu and JR sides without descending to street level.
