After the death of his father, Hideo and his mother Shigeko leave
Ueda, Nagano, for
Tokyo, where she starts a job at a
ryokan, while Hideo moves in with his uncle's family. He befriends the slightly younger Junko, the daughter of Shigeko's employer Naoyo, herself the mistress of a married businessman who finances the ryokan. The two children start making repeated trips around the city together, which finally lead them to the ocean that Hideo only knows from pictures. Hideo is eventually left alone when his mother runs off with a guest and Junko moves away after her father sold her mother's business. ==Cast==
