• Oedo Line: Shin-egota ⇄ Nakai

Ochiai-minami-nagasaki Station opened on 19 December 1997 as part of the Toei Line 12 extension from Nerima to Shinjuku, in Shinjuku Ward, Tokyo. Line 12 was rebranded as the Ōedo Line on 20 April 2000. The station sits on the Shinjuku-Toshima boundary — its provisional name was simply Minami-Nagasaki, but officials hyphenated the names of the two neighbourhoods to acknowledge the location — and remains the westernmost and northernmost stop in Shinjuku Ward. PASMO IC-card acceptance began on 18 March 2007, and a third street-level entrance (A3) integrated with the i Terrace Ochiai-Minami-Nagasaki retail building was added on 30 March 2012. The platform is laid out as a single underground island serving two tracks with a noticeable curve.

The arrival announcement names Sekisui Kinzoku (関水金属, known abroad as Kato Precision Railroad Models) and its Hobby Center Kato among the nearby landmarks — a tip of the hat to the model-railway manufacturer whose head office stands just steps from the station.
