Keiichi Nakagawa works as a patrol officer at the Kameari Kouen-Mae Police Box. His Japanese and French heritage underpins a high-class upbringing and education. He is the sole heir to the Nakagawa Corporation, a multinational conglomerate led by his father Ichiro Nakagawa. This position grants him extreme wealth, enabling access to luxury like a red Ferrari and extravagant actions such as ordering Fijian ice for immediate helicopter delivery. Despite his privilege, Nakagawa demonstrates a dedicated work ethic and commitment to his police duties, consistently earning approval from his supervisor Daijiro Ohara. Nakagawa's appearance reflects his affluent background. He is tall and always wears a distinctive yellow police uniform custom-designed by Pierre Cardin, valued at approximately ¥300,000. This uniform features pinstripe details across all clothing pieces in the manga, though the hat is absent in the anime. Seasonal variations include a short-sleeved summer version. His brown hair is swept back, extending to his neck, with eye color depicted as dark blue in the anime and black in the manga. Personality-wise, Nakagawa is even-tempered and cooperative, making him an ideal officer within the police box. He frequently opposes the controversial schemes of his colleague Kankichi Ryotsu, though his attempts to dissuade him rarely succeed. Nakagawa exhibits intelligence in business and finance, reflecting his corporate upbringing, but his sheltered life results in naiveté about everyday realities. Under his composed exterior lie occasional emotional vulnerabilities stemming from his familial relationships. His mother Sayuri, a pianist and singer, and his fashion-model younger sister maintain globally busy schedules, while his CEO father allocates only minutes annually for rushed meetings. This familial absence leads to documented periods of loneliness and near-insanity when reunion attempts fail. Rare displays of erratic behavior can occur during alcohol consumption or repeated personal failures. Nakagawa's relationships are defining. Physical interactions with his family are minimal due to their demanding careers. Professionally, his dynamic with Ryotsu blends steady friendship with frequent exasperation over Ryotsu's antics; Nakagawa often provides financial or logistical support via Nakagawa Corporation employees for Ryotsu's less problematic ventures. His rapport with Reiko Katherine Akimoto reveals significant parallels: both share mixed Japanese-European heritage, extreme wealth, specialized talents, and nearly identical approaches to advising colleagues, establishing them as platonic counterparts. Nakagawa remains a "chick magnet" in police marriage surveys, though his romantic tendencies appear ambiguous. Beyond the narrative, Nakagawa's cultural recognition includes a bronze statue in Kameari's Lirio Hall district, depicting his signature smile and sophisticated demeanor. This statue is one of 15 commemorative installations celebrating the franchise's setting and characters.
