Himawari Nohara is the infant daughter of the Nohara family, born on September 27, 1996. She possesses light skin and short, curly orange hair, typically dressed in a yellow sleeper with a white bib. As a baby, she doesn't speak verbally, though subtitles sometimes convey her thoughts. She exhibits a mischievous and energetic nature, crawling at high speeds and often treating the family dog, Shiro, as a plaything. Himawari shows a distinct attraction to shiny objects like jewels and brand-name goods, even discerning real jewelry from fakes. This extends to mimicking her mother's interest in handsome men; her brother Shinnosuke sometimes calms her using cutout masks of actors. She copies Shinnosuke's antics, disrupts the household, and avoids blame due to her infancy. She dislikes onions and refuses them, leading to reprimands, yet cares for her family. In "Crayon Shin-chan: Blitzkrieg! Pig's Hoof's Secret Mission," she travels to Hong Kong with her parents to rescue the kidnapped Shinnosuke. During the climax at Pig's Hoof headquarters, her interference with the antagonist Mouse's computer operation disrupts a virus spread, enabling Shinnosuke to resolve the crisis. Future depictions, like "Super-Dimension! The Storm Called My Bride," show her as a 20-year-old police officer wearing a yellow biker jacket, black-and-yellow pants, green gloves, boots, and a white scarf. She retains her habit of blushing at compliments and a similar facial expression when noticing attractive men. Her police work involves assisting arrests, though she neglects frequent family visits. Non-canonically, such as in Movie 20, she appears as the princess of the Sunflower People, wearing a longer princess dress variant of her sleeper adorned with purple pearls, an extended collar bib, and a tiara. Special manga chapters depict her at age five, displaying playful and chaotic behavior similar to Shinnosuke, causing significant trouble that even a 10-year-old Shinnosuke struggles to manage. Her name, meaning "sunflower," originated from a viewer submission contest, reflected in floral motifs occasionally seen on her clothing and toys.
