Ōe, an ageing Tokyo novelist, is caught in a sudden summer shower in the back lanes of Tamanoi, and a young woman named Oyuki ducks under his umbrella and takes him to her room in the unlicensed quarter. Through the summer he visits her regularly, never telling her who he is. When she hints that once her debts are paid she would like to become his wife, he quietly stops coming and lets the relationship end with the autumn.
The narrator goes east of the river to research settings for a novel about a schoolteacher who runs away from his family. His real affair with Oyuki starts to mirror the plot he is drafting. Treating experience as material keeps him partly a spectator, so he can feel tenderness without committing, and the observing stance becomes both his art and his evasion.
The narrator dresses shabbily and hides his name and profession, and Oyuki takes him for a shady figure, perhaps a seller of illicit books. Because nobody in the quarter knows him, he is freed from reputation and obligation and can move through its life as he pleases.
The book argues that the texture of an older, Edo-flavoured Tokyo lives on only in poor, unregulated districts like Tamanoi. The official city of cafés, radios and Ginza glitter erases the past, so the nostalgic has to seek it in places respectable society looks down on, knowing they too are about to disappear.
