History
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, with the fourth track entering service in September 1992 to give the station its present two-island, four-track elevated layout. Platform doors on tracks 1 and 4 began operation on 10 December 2017.

Notes
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.
