Kazusa-Azuma Station has dual opposed side platforms serving two tracks, with a three-sided rain shelter built onto each platform.

After World War II, the JGR became the Japanese National Railways (JNR).

The station has been unattended since 1954, when scheduled freight operations were also discontinued.

With the division and privatization of the Japan National Railways on April 1, 1987, the station was acquired by the East Japan Railway Company.
