The Setting Sun

Kazuko's family, an old aristocratic line stripped of most of its wealth by postwar land reform and taxation, retreats from Tokyo to a small mountain house, and Dazai stages the family's material decline as the literal end of an entire class: Kazuko's mother, described as the last person capable of eating soup with real elegance, embodies a grace that has no further use in the world Kazuko now has to survive in, farming vegetables she was never raised to grow.

Naoji, Kazuko's morphine-addicted brother, supplies the novel's other major voice through diary entries and letters reproduced at length, and his self-loathing account of the same collapse reads as Kazuko's opposite response to identical material: where she is groping toward reinvention, he is dissolving, and Dazai lets both readings sit side by side rather than favoring one. The narrator's own phrase for herself and Naoji, 'victims of a transitional period of morality,' names the novel's real subject: not poverty itself, but the vertigo of inheriting no rules for how to live once the old ones have stopped applying and no new ones have arrived to replace them.

Kazuko's pursuit of Uehara, a dissolute, married novelist she has idolized since glimpsing his photograph as a girl, is deliberately not romantic in any conventional sense. She wants a child by him specifically as an authored act, proof that she can generate a new moral order for herself rather than simply inherit the collapsing one she was born into, and Dazai is careful to make this project cost her Uehara's affection almost entirely, since what she's really courting is the child, not the man.

Postwar land reform and the new constitution's abolition of the peerage genuinely did dismantle Japan's old aristocratic class within a few years, and Dazai, who came from a wealthy landowning family himself and spent his career fascinated by decline and self-destruction, wrote The Setting Sun the year before his own suicide by drowning with a lover in 1948. The title's imagery, an old Japan setting like the sun over Kazuko's mother's generation, is deliberately answered by Kazuko's own closing claim to represent a new dawn rather than an ending, even as her creator's biography suggests he found that claim harder to believe than his narrator does.
