Shuji Tsushima (1909–1948), better known by his pen name Osamu Dazai, was a Japanese writer. Many of his works, including the novel No Longer Human (1948) and the novella Schoolgirl (1939) are considered modern classics in Japan. His life was marred by addiction, depression and impoverishment, but his works soared in popularity, particularly in the post-war years. He died by suicide in 1948.
