Kisho Kurokawa architect & associates (KKAA) has provided technical expertise in the fields of architecture, urban design, regional and new town planning, landscape design, socio-economic planning, long-range development planning, and futures forecasting for government and private agencies both in Japan and abroad. When approaching a particular project, the architects, planners and engineers comprising the Group focus on the concepts of the "symbiotic theory", postulating that architecture as well as urban and social structures should enhance the ambivalent, heterogeneous nature of man. This theory, which has inherently been manifest in every culture, aims to probe the interrelationship between architecture and nature, man and technology, history and the future, and various differing cultures by creating intermediacy and having these elements supplement each other. In applying these concepts, the practicing consultant includes in each project plan an understanding of how the structural and causal variables are integrated within a constantly changing environment. The group thus strives to discover the best possible solutions for concrete social needs. Based on the above-described organization and design approach Kisho Kurokawa architect & associates (KKAA) have executed more than 100 projects over the past 40 years.
