In December 1969, Doraemon comic titles published continuously in six children's monthly magazine. Magazines are magazines Yoiko, Youchien, Shougaku Ichinensei, Shougaku Yonensei, and since 1973 the magazine Shougaku Gonensei and Shougaku Rokunensei. Stories contained in these magazines is different, which means the author of this story should be written more than 6 stories each month.

In the original storyline to the manga, Doraemon is sent back from 22nd century to the present day to aid Nobita Nobi, a highly-unlucky fourth-grader from Nerima in Tokyo, by his great-great-grandson Sewashi. He sent Doraemon to the present day to help out his great-great-grandfather so that Doraemon will help improve Nobita's circumstances so that his descendants, including Sewashi, could enjoy a better future. When Doraemon is "off-duty", his sister Dorami sometimes goes back in time from 2112 to the present day to visit Nobita.

The story focused on Nobita everyday life, the main character. Doraemon has a four-dimensional pocket which he filled with objects from the future. Often Nobita come whining because of problems at school or in the neighborhood, after begging or forced, Doraemon will issue a tool that helps Nobita resolve the problem, get revenge, or just show off to friends.

However, Nobita usually goes too far, ignoring the advice or command Doraemon, and as a result fell into a deeper problem. Sometimes, Nobita's friends steal the device and ends in chaos due to incorrect use.

Television series

After a brief and unpopular animated series in 1973 by Nippon Television, Doraemon remained fairly exclusive in comic from until 1979 when a newly formed animation studio, Shin-Ei Animation (Now owned by TV Asahi) produced an anime series of Doraemon. This series became incredibly popular.

Doraemon co-creator Fujimoto Hiroshi (Fujiko F. Fujio) died on Sept. 23, 1996, of liver failure at age 62; he is survived by his wife Masako and three daughters. Co-author Motoo Abiko (Fujiko Fujio A), who split off in 1987, said "We separated because we would go our own ways. But we both wanted to create the same comics."

Apparently, Mr. Fujimoto initially came up with Doraemon in 1969 after tripping on his young daughter's toy, hearing a neighborhood cat fight, and wishing he had a machine to generate a new comic concept. Between the toy's shape, the cats' yowling, and the longing for a machine to solve his problems, he came up with a robot cat with a pocket containing all sorts of problem-solving gadgets.
