• Tsurumi Line: Anzen

Ōkawa Station opened on 10 March 1926 as a freight-only stop on the Tsurumi Rinkō Railway, a private operator serving the Keihin industrial belt. Passenger service began on 28 October 1930; the line was nationalised on 1 July 1943, making the station part of the Ministry of Railways' (later JNR) Tsurumi Line, and it was destaffed on 1 March 1971. With the privatisation of JNR on 1 April 1987 the station passed to joint operation by JR East and JR Freight; Suica IC service began on 22 March 2002. The last freight train ran on 10 March 2008, and the scheduled freight slots were abolished on 15 March 2008. Ticket-machine sales and IC top-ups ended on 30 September 2016. The station carries number JI 61.

Ōkawa is the southernmost rail station in Kawasaki and lies at the end of the Tsurumi Line's Ōkawa branch. Passenger trains run only during weekday morning and evening peaks (with three trains total on weekends as of 2025), so for around eight hours during the daytime there is no service; passengers can reach Musashi-Shiraishi on foot in about 15 minutes. The station name honours Heizaburō Ōkawa, Japan's first paper-making engineer and "king of paper," whose Fuji Paper Company was, when the line opened, closely tied to the Asano zaibatsu that owned the Tsurumi Rinkō Railway.
