Sasakawa Station was opened on November 10, 1931 as a station on the Japanese Government Railway (JGR) for both freight and passenger operations. At the time, it was the terminal station for the Narita Line, until the line was extended to Matsugishi on March 11, 1933. After World War II, the JGR became the Japan National Railways (JNR). Scheduled freight operations were suspended from October 1, 1962. The station was absorbed into the JR East network upon the privatization of the Japan National Railways (JNR) on April 1, 1987.
