"Mighty Atom," originally created by Osamu Tezuka, began serialization in the April 1952 issue of the monthly boys' magazine "Shonen" (Kobunsha), following the long-running science fiction manga "Mighty Atom," which began in the April 1951 issue and ran for a year. Full-scale television broadcasting began a year later. At the time of its launch, television stations shot live TV dramas based on popular novels, similar to feature films. However, beginning in 1957, attempts were made to produce film works that could be both broadcast on television and shown in theaters. This led to the creation of television films, which were produced outside the confines of a television studio and shot on 16mm film.
