This study considers the Olympic legacy in relation to the Games of the XXX Olympiad in 2012. First, it argues the concept of an Olympic legacy and verifying 2012 Candidature procedure and questionnaire. Second, it analyzes the 2012 candidate file and Report of the IOC evaluation commission for the Games of the XXX Olympiad in 2012 to obtain additional information about the plan for leaving a legacy in each candidate city. Third, it provides further insight into the legacy of the Olympic movement. Based on analysis of the 2012 candidate files, the legacy created in the host city/region is presented in terms of both tangible and intangible aspects. The intangible legacy serves as a driving force for the tangible legacy. The IOC evaluation commission is appreciative of the importance of such a legacy, which includes city development, the possibility for development of sports, and plans for environmental improvement. However, in order to maintain the uniqueness of the Olympic movement, the IOC should construct a system to take stock of intangible legacies as well. In the final analysis, it appears necessary to make best use of the ideas expressed in the fundamental principle of Olympism, which is to construct a legacy for reorganizing sports education.
