Tamako Nobi

Tamako Nobi (野比 玉子のび たまこ) (maiden name Tamako Kataoka 片岡 玉子かたおか たまこ) (Tammy in the United States and UK airings) (height: 5'10​") is Nobita's mother, Nobisuke Nobi's wife, and the semi-tertiary villainess of the Doraemon series. She is very serious about Nobita's test marks, (which are zero most of the time) When she finds out where Nobita hides his examination answer sheets, her punishments involves yelling, reducing his pocket money, or (rarely) spanking him. Nobita's mother is also serious about Nobita doing his homework, which he generally never does. She also sends him out on shopping errands, but Nobita usually forgets to buy them after he returns home. Tamako dislikes animals in the house and Nobita is the usual suspect for this when Tamako seems to sense an animal in the house.

Her real name is Tamako Kataoka, but it was changed to Tamako Nobi when she married Nobisuke Nobi (her brother-in-law's older brother). She usually tells Nobita to study and not to play, but during winter, she urges Nobita to go out and play but Nobita refuses and tells her it is better to warm up in the blanket. She is always worried about her weight and tries different diets to reduce it. She is always jealous of Mrs. Honekawa, though she doesn't show it.
