From the outset they adopted a collaborative style where both worked simultaneously on the story and artwork, but as they diverged creatively they started releasing individual works under different names, Abiko as Fujiko A. Fujio (藤子不二雄Ⓐ, Fujiko Fujio Ē), and Fujimoto as Fujiko F. Fujio (藤子・F・不二雄, Fujiko Efu Fujio). Throughout their career they won many individual and collaborative awards, and are best known for creating the popular and long-running series Doraemon, the main character of which is officially recognized as a cultural icon of modern Japan.[4] Some influences of most of their projects are the works of acclaimed manga artist Osamu Tezuka and many US cartoons and comic books - including the works of Hanna-Barbera.
