History
Higashi-Nagasaki Station opened on 15 April 1915 on the Seibu Ikebukuro Line in Toshima, Tokyo, 3.1 km from the line's southern terminus at Ikebukuro. The district itself was named Nagasaki, but the station was given the "Higashi" (east) prefix to avoid confusion with the much larger Nagasaki Station in Kyushu. The station has two ground-level island platforms serving four tracks, and is sized for ten-car trains, although only all-stations local services call. In fiscal 2012 the Seibu Railway introduced its line-wide numbering scheme, and Higashi-Nagasaki was assigned station number SI03.

Notes
The local district is actually called Nagasaki; the station carries the "Higashi" (east) prefix purely to distinguish it from the famous Nagasaki Station in Kyushu, more than 1,000 km away.
