Adaptations of Tezuka stories

Osamu Tezuka was a Japanese manga artist, cartoonist, animator, and film producer. 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.

Tezuka began what was known as the manga revolution in Japan with his New Treasure Island published in 1947. His legendary output would spawn some of the most influential, successful, and well-received manga series including Tetsuwan Atom, Jungle Taitei, Black Jack, and Hi no Tori, all of which won several awards.
