Osamu Dazai
Tsushima kept his promise and settled down a bit. He managed to obtain the assistance of established writer Masuji Ibuse, whose connections helped him get his works published and establish his reputation. The next few years were productive for Tsushima. He wrote at a feverish pace and used the pen name "Osamu Dazai" for the first time in a short story called "Ressha" ("列車", "Train") in 1933: his first experiment with the first-person autobiographical style that later became his trademark.
