History
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, separated the inner-and-outer-loop 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.
