The JR Central station has two elevated island platforms serving four tracks, of which only the inner tracks (tracks 2 and 3) are normally used. The station building is underneath the platforms and has automated ticket machines, TOICA automated turnstiles and is staffed.
Gamagōri Station opened on September 1, 1888 when the section of the Japanese Government Railway (JGR) connecting Hamamatsu Station with Ōbu Station was completed. This line was named the Tōkaidō Line in 1895. On July 24, 1936, the Mikawa Railway (now part of Meitetsu) connected to Gamagōri Station. The JGR became the JNR after World War II. The JNR portion of the station was extensively remodeled in the mid-1960s, with a new station building completed from 1968-1969. The Meitesu portion was likewise remodeled in the early 1970s, with a new station building and bus terminal completed in 1972. With the dissolution and privatization of the JNR on April 1, 1987, the JNR station came under the control of the Central Japan Railway Company. The Tōkaidō Line tracks were elevated in 2003-2005, and a JR station building was completed in 2006. Automated turnstiles using the TOICAIC Card system came into operation from November 25, 2006.
Station numbering was introduced to the section of the Tōkaidō Line operated JR Central in March 2018; Gamagōri Station was assigned station number CA47.[1][2]
