Shin-Koiwa Station opened on 10 July 1928 on the Sōbu Line in what is now Katsushika ward, eastern Tokyo, and came under East Japan Railway Company at the privatisation of Japan National Railways on 1 April 1987. The station serves both Sōbu Line Rapid trains and Chūō-Sōbu Line local services, with two island platforms over four tracks. After a cluster of platform incidents between July 2011 and June 2013 — thirteen in which passengers were struck by trains — JR East installed automatic platform gates on the Rapid Line platforms in 2018; because the line uses 300-metre trains, the resulting set of doors was reported as the longest of its kind installed at any station at the time.

When automatic platform doors were installed on the Sōbu Rapid Line platforms in 2018, the 300-metre-long installation broke the previous world record set by East Tsim Sha Tsui station in Hong Kong.
