This paragraph talks about the character played by Ryuhei Matsuda in the film. He plays the role of an eccentric part-time philosophy lecturer who spends his days doing nothing but lying around his brother's house reading manga. He has a peculiar personality, often using strong arguments and occasionally saying surprising things. When he becomes passionate about something, he shows incredible energy and determination. The story is told from the perspective of his nephew, Yukio (played by Tatsuki Nishi), who initially doesn't have a good impression of his uncle. However, a chance encounter leads the uncle to meet a woman he falls in love with at first sight (played by Mikayoshi), who needs to return to Hawaii to take over her grandmother's coffee plantation. The uncle and nephew then embark on a journey to Hawaii, starting their quest to pursue the woman of his dreams. The film is adapted from the children's literature of the same name by Kitamura in 1972.
