Known as Sidney, Specky, Nobi Nobi and Noby, in some of the English localizations of the anime, Nobita is usually depicted as an elementary school student in Tokyo's Nerima Ward and the only child of Nobisuke and Tamako Nobi, who is perpetually looked after by the series' title character, a robotic cat from the future sent back in time by Nobita's descendant.
