Nobita's mother, whose full name is Tamako Nobi and whose maiden name is Tamako Kataoka, is a central figure in the household and appears in the series more frequently than her husband. She is a stay-at-home homemaker responsible for cooking, cleaning, and managing the family finances, and she is known for her stern and serious demeanor, especially when it comes to Nobita's academic performance. Tamako is deeply invested in her son's education and frequently scolds him for his poor test results, laziness, and tendency to hide failing grades, punishing him mainly through long lectures rather than physical discipline. Despite her strict exterior, she genuinely loves Nobita and cares for him deeply, as shown when she prepares his favorite meals and snacks, worries when he runs away from home, and prays for his safety. Her motivations are rooted in a desire for Nobita to succeed and become responsible, and she occasionally turns to Doraemon for help by asking him to use his gadgets to solve household problems or guide Nobita. In terms of role, she is the primary parental authority in the daily stories, providing both conflict and warmth, and her interactions with Doraemon are often practical, as she sometimes enlists his futuristic tools for chores or parenting. Key relationships include her husband Nobisuke, with whom she shares the tasks of raising Nobita, her son Nobita, whom she both disciplines and nurtures, and Doraemon, whom she treats as a helper and a member of the family. Over the course of the series, her personality shows some development, with early portrayals being somewhat more lenient and sweet before she became known for her stricter manner, though she consistently demonstrates her love through actions like preparing lunches and showing concern during moments of crisis. Notable abilities include her skill in household management, her sharp eye for detecting Nobita's mischief, and her resourcefulness in maintaining the household budget, often vetoing unnecessary expenses such as a computer for Nobita. She is also physically recognizable by her round glasses, which Nobita inherits from her, and her typical homemaker attire. Overall, Tamako embodies the archetype of a caring but firm mother whose strictness masks a deep and unwavering affection for her family.
