Abstract
Japanese PFI Law was enacted in Japan in 1999. In these eleven years almost all PFI projects were for buildings, while the infrastructure projects were only about 5% in total. Regarding to the road projects that have been managed by the government, there are various bottlenecks for the implementation of PFI. The purposes of this paper are firstly to investigate the time series trend of the PPP projects in the wor ld, secondly to make international comparative study of the PPP-related institutions, and thirdly to propose the desirable improvements of the Japanese institution in many countries. The key issues of the proposal are the support systems for the risk management by the government which squares the rationale and transparence and the deregulation. Finally introduction of PFI scheme into the toll roads which managed by the public corporations of local governments are proposed as a first step in Japan.
