Description
Higeoyaji, whose real name is Shunsaku Ban, is a recurring character throughout the Astro Boy franchise and a prominent figure in Osamu Tezuka's broader body of work. The nickname Higeoyaji translates literally to "Old Man Mustache," a direct reference to his most distinguishing physical feature: a thick, white mustache that dominates his face. He is consistently depicted as a short, portly, middle-aged man who is balding, and he typically dresses in business casual attire such as sport coats and ties. His distinct visual design originated from a caricature drawn by one of Tezuka's high school classmates of his own grandfather, which Tezuka adapted into a character when he was just sixteen years old.
The character's personality is as bold and unmistakable as his appearance. Higeoyaji is loud, boisterous, and outspoken, with a short temper that often leads him to overreact or jump to conclusions. Despite these impulsive tendencies, he is fundamentally good-natured and possesses an unwavering devotion to justice. He is known to be physically courageous, not hesitating to use his fists to protect others or confront wrongdoers. Underneath his gruff and sometimes harsh exterior, he is a loyal ally who genuinely cares for the well-being of those around him, particularly his students.
Within the Astro Boy narrative, Higeoyaji serves a dual professional role. He is most frequently portrayed as a schoolteacher, often serving as Astro Boy's homeroom instructor, while simultaneously working as a private detective. This combination allows him to be both a mentor in the classroom and an active participant in solving crimes and mysteries throughout Metro City, sometimes teaming up with Astro himself. His opinion on robots has varied slightly across different adaptations. In most incarnations, particularly the original manga and the 1980s series, he is a strong and vocal supporter of robot rights, gladly welcoming Astro into his classroom as a student. However, in the 2003 anime series, he is initially portrayed as distrustful of artificial intelligence, but he quickly warms up and changes his beliefs after working alongside Astro and witnessing his character firsthand.
The character maintains several key relationships that are central to his role. He is a good friend of Professor Ochanomizu, which is how he often becomes acquainted with Astro. He has a family connection to a nephew named Kenichi, who frequently appears as his assistant in detective work, and in the 2003 series, he is the uncle of a niece named Yuko Kisaragi. He also has a long-running and well-documented feud with the villain Skunk Kusai, who often taunts him.
Higeoyaji's portrayal has seen subtle shifts and variations across different series and films, demonstrating his adaptability as a character. In the original manga and the 1963 anime, he was directly adapted as a loud and somewhat clumsy detective who is nonetheless a strong fighter. The 1980s series emphasizes his role as a caring teacher and friend to Professor Ochanomizu, while also highlighting unusual hobbies like judo and flower arranging. In the 2003 series, his role is somewhat scaled back, and he works as a private detective focused on minor cases like lost pets before becoming involved in larger adventures. In the prequel series Atom: The Beginning, he appears as a fifteen-year-old science enthusiast without his signature mustache, showing a much younger version of the character. The 2009 CGI film renames him Mr. Mustachio, where he works as a schoolteacher for Toby Tenma. Across these different versions, his core attributes of being a short-tempered, justice-driven, and ultimately good-hearted individual remain consistent, solidifying his role as a beloved fixture in Tezuka's universe.
