More than seven decades after they were first released, the dark novels of Osamu Dazai have become a publishing sensation, as a new generation of readers engage with his bleakness, humour and brilliance There’s no question that Japanese literature has been one of the outstanding successes for British bookshops in recent years: in 2024 close to half of the bestselling translated fiction titles were from Japan. Much of the Japanese fiction translated into English fits into broad categories – cats, crime, coffee shops – but one surprise bestseller stands alone. Sales of books by Osamu Dazai, who killed himself in 1948 aged 38, have rocketed in the last few years. His best-known novel, No Longer Human (1948), has sold more than 75,000 copies in the UK alone. An intense semi-autobiographical account of one man’s alienation, it was the last work of fiction completed before Dazai’s death.
