A number of Akutagawa's works during the Taisyo period were a reorganization of the ancient narrative literature during the Heian and Kamakura periods. This study aims to clarify the modern spatial perception in Akutagawa's works by comparing his works with the pre-reorganized works. We found out the following things. First, Akutagawa's works are semantically and spatially richer than the pre-reorganized works. Second, in the pre-reorganized works the style of spatial description is more perticular while in Akutagawa's works the description is more universal.
