Abstract
Although the economical effect of historical sites is a core issue when considering them as a resource for tourism, the matter has hardly been verified in actual situation. This paper discusses the real economical effect of sites, drawing on results from questionnaires that have been collected during the summer of 2005, from two archaeological parks of the Jomon period in Japan: Sannai-Maruyama and Goshono. For two sites, the economical effect has been evaluated with consideration for the consumer behaviour of visitors.
