| Abstract: | Nationwide, Japan has investigated the current state of underground space use for district in which urban redevelopment has been completed, as well as land utilization under buildings in ward sections of Tokyo. These investigations have shown that promotion of effective use of underground space is essential to integrating the surface and subsurface in order to create a community that provides good amenities and enhances safety in urban areas. To fully achieve this goal, it will be important to develop projects in close cooperation with planners, users and administrators. |
