The Setting Sun (New Directions Book)
Novel by Dazai Osamu, published in 1947 as Shayo. It is a tragic, vividly painted story of life in postwar Japan.  The narrator is Kazuko, a young woman born to gentility but now impoverished. Though she wears Western clothes, her outlook is Japanese; her life is static, and she recognizes that she is spiritually empty. In the course of the novel she survives the deaths of her aristocratic mother and her sensitive, drug-addicted brother Naoji, an intellectual ravaged by his own and by society's spiritual failures. She also spends a sad, sordid night with the dissipated writer Uehara, and she conceives a child in the hope that it will be the first step in a moral revolution.  --The Merriam-Webster Encyclopedia of Literature
