Sudden Shower is one of the most representative masterpieces of Junnosuke Yoshiyuki and the 31st Akutagawa Prize winning work. In previous studies, many people thought that the novel only described how the 「slutty youth」 generated a feeling for the prostitutes and criticized the works focusing on relieving fatigue and trauma through female bodies. However, a more in-depth study on the image of prostitutes portrayed in the Sudden Shower is a great tool for Junnosuke Yoshiyuki to criticize the post-war Japanese society from the special perspective of whoremasters and prostitutes.
