Description
The character known as Higeoyaji, whose real name is Shunsaku Ban, is a recurring figure throughout the Astro Boy franchise and many other works by Osamu Tezuka. His nickname, which translates to "Old Man Mustache," is a direct reference to his most distinctive physical feature. He is typically depicted as a short, portly, middle-aged man who is balding and possesses a thick, white, U-shaped mustache. His standard attire is business casual, often seen in sport coats and ties. He is also known for speaking with a Kansai accent.
Higeoyaji was created in 1944 and is considered one of Tezuka's earliest characters. The visual design was inspired by a caricature drawn by a classmate in high school, which depicted the classmate's own grandfather. Tezuka adopted and refined this image, and the character made his official debut in the 1945 manga Ghost Men.
Personality-wise, Higeoyaji is defined by his loud, boisterous, and deeply opinionated nature. He is a hardboiled devotee to justice who will not hesitate to physically intervene if he sees someone being threatened or oppressed. Despite his courage and good intentions, he is also known for his short temper, a tendency to overreact, and a habit of jumping to conclusions or speaking too harshly. While generally a strong supporter of robot rights, some adaptations, such as the 2003 anime, initially portray him as distrustful of robots before he warms up to them after working with Astro.
His role within the Astro Boy story is versatile, but he consistently serves as an adult ally and mentor to the main character. In most incarnations, he is Astro's homeroom teacher, a position from which he advocates for the robot boy's right to attend a human school. Simultaneously, he often works as a private detective, and in several versions, including the original manga, he balances both roles. This dual life allows him to team up with Astro to solve crimes and mysteries around Metro City. In the 2003 anime, his role is specifically that of a private detective who primarily investigates lost pets at the start.
Higeoyaji has several important relationships that define his place in the narrative. He is a good friend of Professor Ochanomizu, which is often how he first meets Astro. He frequently serves as a guardian to his nephew, Kenichi, who often assists him in his detective work. In the 2003 series, he is shown as the uncle of a young woman named Yuko Kisaragi, who is exasperated by his recklessness. He also has a long-running and notable feud with the villain Skunk Kusai, who often taunts him.
The character has appeared in nearly every iteration of the story, showing some development and variation across them. In the 1963 anime, he is a loud and somewhat clumsy but formidable fighter. The 1980 series presents him as a man with a variety of hobbies, including judo and flower arranging, who crashes a live television interview to defend Astro's right to an education. The 2003 series gives him a small character arc, moving from a distrust of AI to becoming a believer in robot rights thanks to Astro. In the 2009 CGI film, he is a minor character renamed Mr. Mustachio, appearing as Toby Tenma's teacher.
Flashback sequences or spin-off series show younger versions of the character. In the manga arc Once Upon a Time, Astro meets a younger Higeoyaji who has black, jagged hair and no mustache. The prequel series Atom: The Beginning features him as a skinny fifteen-year-old with a full head of brown hair and a passion for science and robotics.
Regarding his abilities, Higeoyaji is far more capable than his portly frame might suggest. He is a strong contender in a fistfight and is known to use judo effectively. His profession as a detective grants him sharp investigative skills, and in one episode of the 2003 series, he uses his knowledge of medicine and biology to create a virus designed to neutralize dangerous nanobots. Such moments highlight his hidden depths and resourcefulness.
