Tamako Nobi, born Tamako Kataoka, serves as Nobita Nobi’s mother and Nobisuke Nobi’s wife. Her maiden name arose from the author’s indecision, finalized through random kanji selection. She adopted the Nobi surname upon marrying Nobisuke after a formative train pass incident in their youth. Her family comprises a younger brother, Tamao, an older brother, and a living mother. Physically mirroring Nobita, Tamako sports short hair and round glasses, which she sometimes removes to unveil large, expressive eyes. Her design fluctuates across adaptations, alternating between black or brown hair and varied attire, frequently featuring aprons or skirts. Balancing strict discipline with heartfelt familial devotion, Tamako shifted from gentleness to sternness in response to Nobita’s perpetual laziness and academic struggles. She reprimands his negligence, enforces punishments like allowance cuts or pet bans, and resists frivolous spending, prioritizing frugality. Yet she softens for modest academic progress or remorse over excessive strictness. Her terror of insects—especially cockroaches—triggers comedic overreactions, echoing Doraemon’s fear of mice. As household manager, Tamako meticulously oversees finances, cooking, and cleaning, sometimes aided by Doraemon. She affectionately calls him “Dora-chan” and humorously mishandles his gadgets, sparking unintended chaos. Spin-offs like *Nobita’s Resident Evil* reimagine her drastically: a zombified antagonist who kills Nobisuke. Later entries experiment with hallucinatory visions or epilogue cameos, diverging from her domestic norm. Her past reveals parallels to Nobita’s flaws—childhood laziness and secretiveness—highlighted in time-travel narratives where her younger self faces maternal scolding. Hobbies include ikebana and singing, while her avoidance of beer contrasts with tipsy antics when consuming other alcohols. Though secondary, expanded media explore her depth. She temporarily permits Nobita a pet dog after its helpfulness, bending her usual animal restrictions. In *Robot Kingdom*, she tearfully embraces Doraemon as family, revealing latent tenderness beneath her pragmatic exterior.
