Kurokawa explores the features of Japanese art, culture, and architecture and shares the concepts of: "Ma (interval in time of space); Engawa (veranda); the concept of Senu hima, the moment of silence between acting and acting as described by Zeami in his treatises on the Noh drama; street space; Rikyu grey; permeability = transparency; lattices; and Hanasuki" in his pursuit of symbiosis and the notion of intermediary space. The concepts are rich in metaphor, and 'intermediary space' evokes anarchistic ideas like a Temporary Autonomous Zone (TAZ) by Hakim Bey and 'cruel optimism' by Lauren Berlant.
"The second condition necessary to achieve symbiosis is the presence of intermediary space. Intermediary space is so important because it allows the two opposing elements of a dualism to abide by common rules, to reach a common understanding. I call this a tentative understanding. Intermediary space does not exist as a definite thing. It is extremely tentative and dynamic. The presence of intermediate space makes possible a dynamic, vibrant symbiosis that incorporates opposition."
