History
Shimo-Ochiai Station opened on 16 April 1927 on the Seibu Shinjuku Line in Shinjuku, Tokyo, operated by the private Seibu Railway. It sits between Takadanobaba and Nakai, 3.2 kilometres from the line's Seibu-Shinjuku terminus, with two ground-level side platforms. Seibu introduced system-wide station numbering during fiscal 2012, and the station was assigned the code SS03. The stop is served by roughly six trains per hour in each direction during the off-peak period and provides walking access to Tokyo Fuji University, the International Catholic Hospital and Otomeyama Park alongside the Kanda River.
