The station has four opposed side platforms serving a total of four tracks. The Shinkansen platforms are located on passing loop tracks, allowing faster trains to pass on the two central tracks. The Shinkansen tracks are elevated, and the Tōkaidō line tracks cross underneath. The station building has automated ticket machines, TOICA automated turnstiles and a staffed ticket office.
These cities and towns formed the "Alliance for Mikawa Station". Kōta town subsequently recommended Ashinoya near Kōda Station. Okazaki city recommended Shōna-chō, Okazaki, Anjō city recommended Furui-chō near Hekikai Furui Station, and Nihongi-chō where the Tōkaidō Shinkansen and Tōkaidō Main Line intersect as possible candidate locations. The alliance entrusted the decision to the Aichi prefectural government. On January 5, 1984, the prefectural government decided to build the station in Nihongi, Anjō. Construction work started on July 29, 1985, and the station was opened on March 13, 1988.
Station numbering was introduced to the section of the Tōkaidō Line operated JR Central in March 2018; Mikawa-Anjō Station was assigned station number CA55.[1][2]
