Nobita's father in Eiga Doraemon: Nobita no Esekai Monogatari is Nobisuke Nobi, the head of the Nobi household and a gentle, easygoing presence in the family home. He works as a section chief at an ordinary company, representing a modest middle-class Japanese salaryman, and he is known for his relaxed, laid-back temperament, which in many ways resembles his son's own unhurried nature. His background includes a difficult childhood shaped by the hardships of wartime Japan, an experience that left him with a quiet resilience and a deep appreciation for the simple warmth of family life. He is married to Tamako and also acts as a caring father figure to Doraemon, treating the robot as a true member of the household. In the film, his role is modest but meaningful. Early in the story, he is shown watching the news report about the discovery of a mysterious painting of a lake, a moment that introduces the central mystery of the rare blue color known as Artria Blue, which cannot be reproduced in the present day. Later, at the film's conclusion, he appears in a quieter but important scene: after a news commentator dismisses a child's drawing as having no monetary value, Nobisuke disagrees and observes that the drawing conveys the feelings of the artist, who simply drew something he loved. He praises the picture as a good one, and this encouragement directly inspires Nobita to try painting a new portrait of his father. His motivation throughout is a sincere desire to support his son and to value the emotional honesty of art over its commercial worth, reflecting his belief that genuine expression matters more than technical skill or market value. His key relationships are with his wife Tamako, with Doraemon, and especially with Nobita, to whom he offers gentle guidance rather than pressure or criticism. In terms of development, he serves as a steady, supportive anchor who reinforces the film's central theme that art is about loving what one draws, and his affirming words give Nobita a renewed sense of confidence and purpose. He has no special abilities, gadgets, or supernatural talents; he is an ordinary working man who is somewhat clumsy at practical tasks and sports, but his notable strength lies in his perceptive warmth and his ability to recognize and encourage the sincerity in other people's efforts.
