Hiroshi Nohara is the father of the Nohara family and works as a section chief at Futaba Shoji, serving as the family's primary income source. He shoulders significant financial pressures, including a 32-year mortgage, and typically works extended hours, though he finds time for his family. Hiroshi is a devoted husband to Misae and a caring father to Shinnosuke and Himawari, consistently committed to their well-being despite frequent disagreements over minor matters. His relationship with Shinnosuke involves shared humorous tendencies, like appreciating attractive individuals, often sparking light-hearted conflicts with Misae. In *Crayon Shin-chan: Unkokusai's Ambition*, Hiroshi joins a time-travel mission to the Sengoku period after a Time Patrol officer enlists the family's help to fix disruptions caused by the antagonist Unkokusai. During this journey, Hiroshi and Misae are transformed into a ball by Unkokusai's subordinate Ogin, rendering him largely passive for a portion of the adventure. His primary motivation stems from the theft of Misae's handbag containing critical family documents like their savings passbook and legal seal. Hiroshi's personality blends responsibility and lightheartedness. He exhibits typical salaryman traits, enduring demanding work while maintaining family cohesion. Though he occasionally dreams of office romances, he remains faithful to Misae. Comedic elements include his notoriously odorous socks, often weaponized by other family members. Financially, he relinquishes his salary to Misae, who tightly controls household expenditures, leaving him minimal personal spending money. The film's resolution sees Hiroshi return to the present timeline with his family after Unkokusai's defeat. The aftermath reveals an altered reality dominated by Unkokusai (Pierre Jakoman), prompting another confrontation. Hiroshi plays a supportive role in this segment, culminating in the restoration of normalcy following Jakoman's ultimate defeat.
