No Longer Human

No Longer Human is a 1948 novel by Osamu Dazai. It is a Japanese novel about a troubled man who cannot show others who he really is, so he hides behind a mask of easy humor and lightness. As the book goes on, it moves through loneliness, personal decline, and a growing dependence on alcohol and drugs, while staying focused on the inner state of its central figure rather than on a plot driven by action.

This is a good fit for readers drawn to direct psychological fiction, especially stories built around shame, distance, and self-concealment. The tone is intimate and stripped down, and that is part of what makes the novel stand out. It is often associated with postwar Japanese literature and with writing that stays close to a character’s mind, making it a strong choice if you want something compact, bleak, and very character-centered.
