|Voice Actor|| Sachiko Chijimatsu (1-20)|
Kazuko is very supportive of her children and husband, as well as the Getter Team who she treats like family. She dislikes weapons, having lost her parents from an airstrike in wartime, causing a trauma to act up. This in turn causes some rifts with Dr. Saotome as he was forced to develop weapons against the Dinosaur Empire.
Kazuko is often seen having dinner with her family and their guests during certain times. Occasionally, viewing a battle brings about her traumas and while she does not want her family involved, Kazuko allows them fight knowing that they have to.
