Mr Yamada, whose given name is Kento, is the father of the Yamada household in the anime Chi's New Address. He works as a graphic designer, a profession that occasionally requires him to be away from home or to work at his desk, leaving him less available during the day to spend time with Chi, the family’s kitten. Despite his busy schedule, he is a caring and attentive parent who shows his affection for Chi through practical actions: he regularly buys toys and snacks for her, worries when she is left alone at home, and takes on the less pleasant tasks of bringing her to the veterinarian and trimming her claws. Initially, Chi is drawn to his vintage jeans as a scratching post, and she also associates him with food, which helps her quickly warm up to him. When Chi falls asleep and he pets her, she often dreams of her original mother, suggesting that his gentle touch provides her with comfort and security. His role in the story is that of a supportive and responsible family man who, together with his wife Miwa and son Yohei, adapts to the challenges and joys of living with a curious kitten in a new pet‑friendly apartment. While his primary motivation is to provide a safe and happy home for his family, he also develops a genuine attachment to Chi, treating her as a beloved member of the household. Throughout the series, he shows growth in his willingness to handle the day‑to‑day care of a pet, from bathing her to managing her mischief, and his bond with Chi deepens as she learns to trust him. His notable abilities include his patience in dealing with Chi’s unpredictable behavior and his resourcefulness in solving the practical problems that arise from sharing a small home with an energetic kitten.
