Tamako Nobi, known as Nobita's mother in the Doraemon series, plays a very minor but symbolic role in the film Doraemon the Movie: Nobita's Great Adventure in the Antarctic Kachi Kochi. She is depicted as a slim woman with rounded glasses, similar in appearance to her son, and typically wears a simple blouse and skirt with an apron. Her background is that of a typical Japanese housewife who manages household chores and cooking, often with the help of Doraemon. Her personality in the movie is consistent with her established character: strict and serious about Nobita's responsibilities, such as doing homework and obeying rules, but she also cares deeply for him. Her motivation is to ensure Nobita stays on track, and she expresses her love through discipline and routine. In the story, her role is limited to the very end: after the group returns from their Antarctic adventure and Doraemon shows Nobita that the alien planet's ice is melting, Nobita's mother calls him and Doraemon for dinner. This moment grounds the extraordinary journey in everyday family life, highlighting her function as the anchor of Nobita's home environment. She has no notable abilities beyond her domestic skills, and her relationship with Nobita is that of a caring but firm mother who expects him to grow up responsibly. There is no character development for her in this film; she remains a steady, familiar presence that bookends the adventure.
