Astro Boy, national fame and early animation (1952–1960)

By 1952, Ambassador Atom had proven to be an only mild success in Japan; however, one particular character became extremely popular with young boys: a humanoid robot named Atom. Tezuka received several letters from many young boys. Expecting success with a series based around Atom, Tezuka's producer suggested that he be given human emotions. One day, while working at a hospital, Tezuka was punched in the face by a frustrated American G.I. This encounter gave Tezuka the idea to include the theme of Atom's interaction with aliens. On 4 February 1952, Tetsuwan Atom began serialization in Weekly Shonen Magazine. The character Atom and his adventures became an instant phenomenon in Japan.

Due to the success of Tetsuwan Atom, in 1953, Tezuka published the shōjo manga Ribon no Kishi (Princess Knight), serialized in Shojo Club from 1953 to 1956.

In 1954, Tezuka first published what he would consider his life's work, Phoenix, which originally appeared in Mushi Production Commercial Firm.
