Doraemon (Japanese: ドラえもん) is a Japanese manga series written and illustrated by the manga writing team Fujiko Fujio. The series has also been adapted into a successful anime series and media franchise. The story revolves around a robotic cat named Doraemon, who travels back in time from the 22nd century to aid a pre-teen boy named Nobita Nobi (野比 のび太 Nobi Nobita?).

Doraemon is sent back in time by a young boy named Sewashi Nobi to improve the circumstances of his grandfather, Nobita, so that his descendants may enjoy a better future. In the original timeline, Nobita experienced nothing but misery and misfortune manifested in the form of very poor grades and bullying throughout his life. This culminates in the burning down of a future business he sets up which leaves his family line beset with financial problems. In order to alter history and better the Nobi family's fortunes, Sewashi initially wanted to send a super-robot to protect Nobita, but with his meager allowance he could only afford an imperfectly-made factory-rejected toy: an anthropomorphic robot cat called Doraemon.

Doraemon has a pocket from which he produces gadgets, medicines, and tools from the future. Some of the gadgets are based on real Japanese household devices with fanciful twists, but most are completely science fiction . Thousands of gadgets have been featured in the series with such as the "bamboo-copter" , a small head accessory that allows flight and the "Anywhere Door," a door that opens up to any place the user wishes.

Nobita's's closest friend is Shizuka Minamoto, who also serves as his romantic interest. They are tormentors are tormented by the bully "Gian" and the cunning and arrogant Suneo. A typical story consists of Doraemon using one of his gadgets in order to assist Nobita in various ways, often causing more trouble than he was trying to solve.
