The great transformation from industrial to sustainable society is one of the most important challenges today. “Sustainability” is a key concept to constitute the society of 21th century. This concept that should combine and adjust different fields, like economy, society and environment is however so ambiguous and comprehensive that it is often criticized as meaningless word. In the Symposium we will learn its precise contents defined by an economist, examine if/how we can use it as law category. We consider the new content of property right which can promote the sustainable development, not only in nation state, but also in Asian Region. We will try to get some hints of the concrete law policies for transformation from some examples of reconstructing activity in earthquake-stricken areas.
