Shinnosuke Nohara, known as Shin-chan, is a mischievous five-year-old kindergarten student living in Kasukabe, Japan. His personality blends habitual trouser-dropping to perform the "buri buri" dance (or "wiggly wiggly"/"super cute" dance), scatological humor, and vocalizing phrases like "Buri! Buri!" with brutal honesty and flashes of unexpected maturity. He often misuses language, creating malapropisms such as "promotion" for "promise" and blended greetings like "okonban gozaimasu". Shin-chan displays contradictions, showing surprising competence in activities like running, surfing, kendo, fishing, skiing, and swimming, yet exhibiting laziness regarding chores. His obsessions include the superhero Action Mask, chocolate corn biscuits ("Chocobi"), and an intense dislike of green peppers. He regularly flirts with older women using lines like "Hey, baby, you like onions?", a trait shared with his father and paternal grandfather, but shows no interest in romantic relationships with peers, rejecting advances from kindergarten-aged girls. Family relationships significantly shape him. He inherits stubbornness and gluttony from his mother, Misae, and shares a tendency to admire young women with his father, Hiroshi. Despite frequently teasing his mother, they share a strong bond, evidenced by his distress during her hospitalizations. He acts protectively toward his younger sister, Himawari, often including her in adventures and showing concern for her safety. The family dog, Shiro, was rescued by Shin-chan from abandonment, though he often neglects pet care duties. As a founding member of the Kasukabe Defense Force (KB) with friends Toru Kazama, Nene Sakurada, Masao Sato, and Bo Suzuki, Shin-chan participates in group missions. His dynamic with Toru is notable; though Toru frequently denies their closeness, Shin-chan consistently supports him during emotional crises, and Toru demonstrates deep loyalty in return, such as chasing Shin-chan's departing train in *My Moving Story! Cactus Large Attack!*. In *Arashi o Yobu Jungle* (released as *Storming Jungle* or *Bungle in the Jungle*), Shin-chan's role expands during a cruise ship journey. When monkeys kidnap all adults, he leads his friends and sister on a rescue mission to a jungle island. He interacts with the "Paradise King," who controls the monkeys, and ultimately collaborates with Action Mask to defeat this antagonist and save the captured adults, highlighting his crisis leadership and resourcefulness. Beyond films, video game adaptations like *Arashi no Yobu Cinema Land no Daibouken* utilize his penchant for costumes—such as Action Mask, monkey, frog, and bee outfits—to grant abilities like wall-jumping or tongue-based attacks. These costumes sometimes reference his film adventures, including the monkey outfit from *Arashi o Yobu Jungle*. A persistent fan theory suggests Shin-chan's origin stems from a real child named Shinnosuke Nohara who died in a car accident saving his sister, with his grieving mother's sketches inspiring creator Yoshito Usui. This theory remains unverified by official sources.
