Osamu Tezuka was a Japanese manga artist, cartoonist and animator. Born in Osaka Prefecture, his prolific output, pioneering techniques and innovative redefinitions of genres earned him such titles as "the Father of Manga" , "the Godfather of Manga" and "the God of Manga" . Additionally, he is often considered the Japanese equivalent to Walt Disney, who served as a major inspiration during Tezuka's formative years. Though this phrase praises the quality of his early manga works for children and animations, it also blurs the significant influence of his later, more literary, gekiga works.

A manga artist, also known as a mangaka, is a comic artist who writes and/or illustrates manga. As of 2006, about 3,000 professional manga artists were working in Japan.
