Nobita’s stay-at-home mother. She can be very strict, is usually seen scolding Nobita or sending him out of the house (a typical Japanese household punishment used by parents, unlike grounding which is a Western punishment). She actually loves her son very much, but is disappointed by his lazy attitude and academic failures. Several episodes involve Nobita trying to avoid his mother’s scolding by using Doraemon’s gadgets. Her maiden name is revealed to be ‘Kataoka’. She has a tendency of stopping Nobita from going out to play and force him to study. However, on cold weather days, she almost always urges Nobita to go out and play. In a couple of episodes, Nobita sees her in the past. She is proved to be braver than Nobita but as clumsy as him.
Nobita’s father and laid-back salaryman. He is very considerate of Nobita, often seen arriving home from work to placate Tamako’s anger towards Nobita; this habit may come from Nobisuke’s own childhood, since his father (and Nobita’s grandfather) was very similar to Tamako. He has trouble quitting smoking and is self-conscious about his inability to pass the driving test. He also has a poor memory, is a borderline alcoholic, and sometimes arrives home drunk from nightly business meetings. He was once an aspiring art student. He also likes golf, which most Japanese businessmen and employees play.
Mini-Doras are actually gadgets of Doraemon. They are mini versions of Doraemon, each with a different color. They can think and feel for themselves, and communicate with Doraemon through the “Mini-Dora” language. They act as helpers for all sorts of tasks, such as repairing the internal mechanism of Doraemon.
