Today, historic climates have been preserved by the Ancient Capitals Preservation Law in eight cities including Kyoto. However, the validity to the government expenditures or the land use regulations by this law has not been shown clearly. So, based on the consciousness of the Kyoto citizen, we measured the economic value of this preservation in monetary term, using CVM and Conjoint Analysis. Then we economically evaluated this law, and considered validity of this law and land use regulations by this law. As a result, this economic value is about 2.3 billion-yen per year and the Kyoto citizen dose not want strict regulations for land use.
