In the year 2003, Professor Tenma is distraught when his son Tobio is killed in a car accident. He loses himself in his latest project, creating Atom, a robot boy programmed to be forever good.

Upset that his Tobio-substitute can never grow up, Tenma sells Atom to Ham Egg, the cruel ringmaster of a robot circus. Atom meets the kindly Professor Ochanomizu, who adopts him, inspires him to become a crusader against evil, and eventually builds him a robot "sister," Uran.

Tetsuwan Atom was the first television anime series to air in a 30-minute programming slot. It was broadcast by Fuji Television and aired on Tuesdays when broadcast began in 1963. The first episode debuted on New Year's Day with a 27.4% viewership rating, with the series later peaking at over 40% rating by the following year. From 1964 onward, the airing was changed to Saturdays.

When American television producer the late Fred Ladd helped NBC Enterprises adapt the series for broadcast in the United States in 1963, the title Astro Boy was used instead of the manga's English title Mighty Atom. The change was forced because of its similarity to the contemporary American superhero character Mighty Mouse, which Osamu Tezuka used as a basis for the character Atom.

Mixed Feelings
This review focuses on the original Japanese version (193 episodes) as released on the Tetsuwan Atom Complete BOX DVD sets and is slightly updated from my previous preliminary review.

Tetsuwan Atom is the first “full-length” (30-minute) weekly TV anime. With an ambitious project devoid of a high production budget, Osamu Tezuka pioneered production methods like limited animation, use of recycled footage, and outsourcing animation work when there was hardly any precedent to learn from. Especially early on, this was in many ways an experiment, and it cannot be viewed under the same critical lens as even subsequent 60s works.

In its most basic premise, Tetsuwan Atom has ...
