Résumé en anglais
At the beginning of modern era, the Japan government gave citizens the right to deal with their properties including immovable properties; land and buildings. City planning laws allowed people to make enormous modern buildings in quite a wide aria of the town. It might be one of he reasons of quick modernization of Japan. Many important historic environments were destroyed or are still in critical situation on the other hand.Our conservation of historic townscape had to start with such conditions. Citizens’ right about immovable properties must be guaranteed as much as possible. Wooden houses of middle class citizens might happen to come to the stage of rebuilding. Two storied traditional buildings could be actually too small. To make the conservation rules and systems have been a work to find the balance between cultural values and modernization of the city. After all, conservation system of historic townscape in Kyoto selected the way to continue the character in some way with modern buildings, and to keep the traditional style in some selected districts, rather than preservation of buildings themselves.
