THE TRANSFIGRATION FOLLOWED ENHANCEMENT PERMISSION : Case study on Narai important preservation district for groups of historic buildings

The object of this research is to investigate relationship between the institutional systematization of the architectural reconstruction and the change in townscape, exemplifying Narai Important Preservation District for Groups of Historic Buildings located in Nagano Prefecture as a case study. We compared important changes in the periods before and after specified as the conservation district. And then we confirmed that the systematization brought changes to the historic townscape. Essentially, the value of historic townscape resides in the district itself. The systematization might cause the danger to create "pseudo-historical townscape", and might lose local characters in local historic districts.
