The ‘Rashomon Effect’ is a phenomenon that recognizes the essence differently from one case to the other. It is a coined word derived from Akira Kurosawa’s movie “Rashomon”, which adapts Rashomon of Akutagawa Rinosuke and Yabunonaka.. The popular Rashomon effect has been remodeled from various countries all over the world, and Akutagawa literature, which can be regarded as a prototype of the contents, has been neglected. Therefore, I would like to consider what the prototype meaning of ‘Rashomon effect’ originates from Akutagawa literature. The character of Akutagawa literature can be seen in today’s media as a selfish behavior of a human being with a strong desire for achievement that truly believes in a fictional world while repeating false words and actions. Akutagawa has given the Rashomon pavilion and the courtroom as a symbolic space where events are held in Rashomon and Yabunonaka, and it is a starting point of modern consciousness and human perception. And the judgment in the Yabunonaka resulted in the fact that the reality of the event was blocked, not the truth. In addition, he focused on the characters of the characters who represent the times in the symbolic space of modern times. It was in the form of a Yabunonaka that the character of each person in Akutagawa literature could be maximized. All were divided into seven paragraphs, and conflicts and confrontations between the characters were originally blocked. As a result, human narrow-minded egoism has left the fact that the nature of the event itself can be interpreted differently. Here, there was the prototype meaning of ‘Rashomon effect’. Kurosawa, who did not miss such an awareness of the artist, used it as a technique for directing the film “Rashomon” and derived the philosophical theme of “Rashomon Effect” based on Akutagawa literature. The original meaning of ‘Rashomon Effect’ originating from Akutagawa literature was accepted and communicated even beyond the times and countries.
