History
Machiya in Arakawa ward is served by three operators clustered around the same intersection. The earliest stop was an Ōji Electric Tramway streetcar halt opened on 1 April 1913 (now Machiya-ekimae on the Toden Arakawa Line / Tokyo Sakura Tram). Keisei Electric Tramway added its station on 19 December 1931, and the Eidan Subway Chiyoda Line followed on 20 December 1969 with an unusual stacked split-platform underground arrangement. The Chiyoda Line facilities transferred to Tokyo Metro at the privatisation of TRTA on 1 April 2004, and Keisei Main Line numbering in 2010 assigned the stop the code KS04.

Notes
The Chiyoda Line platforms here are stacked vertically — the Yoyogi-Uehara-bound platform sits 10.4 m below ground and the Ayase-bound platform a further 5.9 m beneath it — because the surface roads above were too narrow for a normal side-by-side layout.
