We analyze life in urban district on the outskirts of Tokyo by ANT. This research is used to identify social and technological elements that are regarded as essential in the modern day and to develop methods that will link to a practical approach. Our presentation describes these methods in detail. We believe that it may be possible to identify particularly important elements in design methods that respond to the complications of the modern day in early modern wisdom and customs, which until now have been overlooked. Today, as the foundations of social norms and traditions that have previously been regarded as self-evident are swaying and the risk society is advancing, these new design methods can be used to respond to an array of issues with a high degree of complication, such as the deterioration of the mental environment and environmental problems without any discernible solution. Since the modern era began, design has solved social problems through the development of objects and systems. However, in terms of the problems stated above, it can also be pointed out that design is both unable to suggest basic solutions and, in addition, forms a part of the social structures that cause these problems. Approaches that follow laws of causality tied to modern methodology cannot be applied to complicated problems where the relationship between cause and effect is unclear. The use of new design methods makes it possible to decipher complicated relationships and apply pre-modern systems to modern life.
