Nobita's mother Tamako Nobi is Nobisuke's wife. Doraemon's series features her as a major supporting character. Nobita's test marks (which are usually zero) are very important to her. If she finds where Nobita hides his examination answer sheets, she yells, reduces his pocket money, cusses him, throws him out of the house, and sends him away (possibly in the future), or spanks him (rarely). Nobita's mother is also serious about him doing his homework, which he doesn't usually do. Additionally, she sends him shopping errands, but Nobita usually forgets to buy them afterward. When Tamako senses an animal in the house, Nobita is usually the suspect. Occasionally, she cooperates with Suneo and Gian to punish Nobita and Doraemon.
