Astro Boy in "Captain Atom" (1951)

Astro initially debuted in the 1951 manga Captain ATOM. His character was received so well by readers that by April of the same year he appeared in his own series, Tetsuwan Atomu, which later got a paperback release in 1975. The series proved such a success that it launched into an international franchise of anime, manga, films and video games. Tezuka, originally designed after traditional Disney characters of the time, Astro's style reflects that of Mickey Mouse. A simple cartoon style of character, although Tezuka would implement some of his own styles into the drawings that would become commonplace for most anime and manga that came after.

Astro became one of the first major manga characters in Japan to successfully adopt widespread merchandise. He has appeared on everything from food items, T-Shirts, mugs, calendars, and stickers. He also became a very successful line of toys and action figures. His success in merchandise continues today especially in items such as Funko's Pop figures.

Since his conception, Astro has become so popular in Japan that he has cemented a status as a cultural icon. Astro's influence as an illustrated character can be compared to others from separate countries such as MIckey Mouse, Popeye, Felix The Cat, Bugs Bunny and TinTin.

Creation and conception

Tezuka atom
Tezuka was a lifelong fan of Disney and he styled many of his early characters based on famous Disney characters. Astro would continue this trend of characters designed after Disney characters, using a simplistic cartoon style. Astro bears a strong resemblance to Mickey Mouse Disney's most popular character. The most prominent feature of Astro's design that borrows from Disney is in the head. His head uses a large circular shape, also being used by many popular American animated characters at that time. Psychologically this suggests Astro's innocence.


Astro Boy wears a green belt, black underpants, red boots and has two spikes on his head.
