Regenerative Preservation of Built Environment

Development of comprehensive methods and technologies to realize sustainable megacities and local communities against big earthquakes

In recent years, damage earthquakes have occurred frequently in many countries including Japan. It is also said that big earthquakes in the subduction zone around Japan and at the inland active faults under megacities will occur in the not-so-distant future in Japan. In order to realize sustainable society and local communities against such big earthquakes, we are working on the regenerative preservation of built environment and the improvement in the safety of living space by reducing the earthquake damage and the ripple effects not only from a view point of natural science but also social science.
