Happōsai Sarutobi is a character from the 1982 anime series Sasuga no Sarutobi. His surname, Sarutobi, meaning flying monkey, is a nod to the legendary ninja Sasuke Sarutobi, suggesting a background steeped in agility and prowess, while his given name, Happōsai, translates to Eight Treasures, hinting at a wide array of skills or knowledge. Within the story's world, he is established as a figure of significant history and authority, having been one of the founders of Shinobinomono High School, a special institution dedicated to ninja training, where he previously served as the principal. The series primarily follows the adventures of his grandson, the protagonist Nikumaru Sarutobi, a short and chubby seventeen-year-old student at the same high school who wields a super technique known as the kamikaze. As a family member, Happōsai is the father of Kasumi Sarutobi, making him a direct link to the younger generation of ninjas navigating their training and rivalries. His role appears to be that of an elder and a mentor, embodying the wisdom and foundational knowledge of the ninja arts, distinct from the energetic and often comedic exploits of the students. The depth of his personal motivations and any significant character development he undergoes over the course of the series are not detailed in available records, but his position as a founder and former principal underscores his integral connection to the setting and the legacy his grandson inherits.
