Osamu Dazai
Also known as Shūji Tsushima, Tsushima Shūji, Dazai Osamu, 太宰 治, 津島 修治
Japanese postwar literature reached some of its most honest personal expression in No Longer Human, a modern classic that continues to sell tens of thousands of copies annually and has been translated into more than 60 languages. Written by Shūji Tsushima under the pen name Osamu Dazai, this prominent body of mid-twentieth-century fiction explores themes of alienation, personal isolation, and self-destruction with direct psychological clarity.
Career & Background
Born in 1909 into a powerful landowning family in Kanagi, Aomori Prefecture, Tsushima attended school in Kanagi, middle school in Aomori City, and Hirosaki Higher School before entering the French Department at Tokyo Imperial University in 1930. He left the university without earning a degree after boasting that he had never attended a single lecture during his five years there. His early life was complicated by addiction, financial instability, illness, and recurring suicide attempts. He married Oyama Hatsuyo in 1931 and later married Ishihara Michiko in 1939, with whom he had three children, including the writer Yūko Tsushima.
Adopting the pen name Osamu Dazai, he published his early novel Gyofukuki in 1933 and assembled his early short stories in the 1936 collection Bannen (The Declining Years), expecting posthumous publication following a 1935 suicide attempt. After World War II, Dazai established himself as a leading member of the Burai-ha (Decadent School) literary group, gaining significant attention with short works like 'Villon's Wife' and major postwar novels. On June 13, 1948, Dazai died by drowning in Tokyo's Tamagawa Josui canal in a double suicide with Tomie Yamazaki at age 38, six days before his body was found on his 39th birthday.
Writing Style & Themes
Dazai's literary work is noted for its ironic wit, gloomy humor, brilliant fantasy, and deeply autobiographical perspective. Influenced by Ryūnosuke Akutagawa, Murasaki Shikibu, and Fyodor Dostoevsky, his narratives frequently address emotional isolation, personal debauchery, and social disillusionment. He demonstrated versatility across forms, publishing subtle autobiographical fiction as well as works like Otogi Zoshi (1945), which reinterpreted traditional Japanese tales. His candid portrayal of psychological struggle and alienation continues to attract readers across multiple generations.
