# The Cast of Astro Boy: Legends Behind the Iconic Anime Series Astro Boy (original title: Astro Boy, known internationally as Astro Boy or Tetsuwan Atomu) remains a cornerstone of anime history and a beloved sci-fi classic. Since its debut in 1963, the series has captivated audiences with its heartfelt storytelling, futuristic themes, and unforgettable characters. Central to its enduring legacy is the carefully assembled cast that brought this 1960s masterpiece to life — from the voice talents that gave Astro Boy emotion and charm to the supporting characters that shaped the rich world around him. ## The Voice Behind Astro Boy: His Human Heart At the heart of Astro Boy is Reiko Osaka, the voice of Astro Boy (Tetsuwan Atomu), whose warm, expressive narration became the emotional anchor of the show. Osaka’s performance captured the innocence, courage, and resilience of the robot boy, making Astro more than a mechanical hero — he became a symbol of hope in a dystopian world.
