In Japan, the revision of the HeritageConservation Act in 1975 added to the protection of ''traditional buildings''. The establishment ofthis system was driven by the public from the bottom up. In the constructionclimax of the 1950s and 1960s, the common practice was to ''demolition and buildnew ones''. At that time, the ''Cultural Relics Preservation Law'' could only protect individual culturalrelics, and the historical blocks of the film could not be protected. Later,they realized that the protection of the ecological environment is for thehuman body. The protection of the historical environment involves the humanmind. This should also be an essential part of modernization, which led to therevision of the Cultural Relics Preservation Act. The ''traditional buildings'' here are roughlyequivalent to the historical streets of Europe, including traditional commercialstreets, traditional residential areas, handicraft workshops, and modernforeign-schedule 80 stainless steel pipesstyle ''foreign halls''. The law stipulates that ''the area where traditional architecture is concentrated and thehistorical environment is integrated with the surroundingenvironment'' should be protected as ''the traditional building group protection area''. The local urbanplanning department first determines the scope of protection through urbanplanning, and then formulates the local preservation regulations. The countrychooses its higher value as the ''important traditional architectural group preservation area''. There are currently47 state-level ''important traditional buildings'' in Japan, and 800 are conductinginvestigations.check here
Japan’s revised ''Cultural Relics Preservation Law'' stipulates that allnew construction, expansion, reconstruction and alteration of topography, treecutting and other activities in the ''conservation area of traditional building complexes'' must be approved, andthe urban planning department should make protection plans. The content is:Identify the objects of protection, list the detailed list of protections,including the various elements that make up the overall historical style;formulate plans for protection and renovation, trim the ''traditional buildings'' as they are, andrebuild ''non-traditional buildings''. Decoration, renovation or demolition of some serious impacts; inaddition to improving infrastructure, governance environment and related firesafety, tourism display, transportation and other aspects of planning. Thedecree also stipulates the method of financial subsidy. The central governmentand the local government each contribute 50% of the subsidy to the outside ofthe traditional building. The subsidy for each household can account for50%-90% of the repair cost. Each protected area can be subsidized by 6-8households per year, which is a plan for gradual remediation.
The Washington Charter, adopted in 1987,summarizes the practices and experiences of countries and summarizes the issuesof protecting the commonality of historical sites. The document lists what thehistorical location should protect:
