• Oedo Line: Tsukijishijo ⇄ Tsukishima

Kachidoki Station opened on 12 December 2000 as part of the Toei Oedo Line in Chuo Ward, taking station number E-17. The opening forecast called for around 14,000 daily boardings, but high-rise residential and office development in Harumi and Kachidoki drove ridership past 60,000 boardings-and-alightings by fiscal 2002, just two years after opening. A major expansion programme from fiscal 2010 added an outer-loop side platform on the south side, leaving the original island platform to inner-loop trains only, joined and enlarged the previously divided north and south concourses, and added a new street-level entrance; the new layout went into service on 11 February 2019, with the overall project completing in June 2020 at a total cost of around 16 billion yen.

Kachidoki is the only station on the Toei Subway whose name is written partly in hiragana rather than entirely in kanji.
