It is the intention of this paper to develop an understanding of architecture from an interdisciplinary point of view, based on an analysis of the concept of "architectural" in Tanizaki Jun'ichiro's essay JOZETSUROKU. Tanizaki argued that the value of novel's plot is like an architectural beauty. We interpret and clarify this argument by using other Tanizaki's essays. "Architectural" means the quality of a work which contains an organic composition. To create a work of art with well trained and sophisticated sense of beauty results in a work which holds a nature of "architectural".
