No Longer Human, also translated as A Shameful Life, is a 1948 novel by Japanese author Osamu Dazai. It tells the story of a troubled man incapable of revealing his true self to others, and who, instead, maintains a facade of hollow jocularity, later turning to a life of alcoholism and drug abuse before his final disappearance. The original title translates as "Disqualified as a human being" or "A failed human". The book was published one month after Dazai's suicide at the age of 38. No Longer Human is considered a classic of postwar Japanese literature and Dazai's masterpiece, which enjoys considerable popularity among younger readers. It ranks as the second best-selling novel by the publishing house Shinchōsha, behind Sōseki Natsume's Kokoro.
