Abstract
Since the end of WWII, social capital stock has been rapidly accumulated in Japan. But it seems that the financial resource will be limited in the near future. In this study, patterns of social capital stock since 1953 are analyzed in terms of both regional and sectoral distribution. And their impact on productivity is evaluated. Furthermore, several predictions are made with regard to the compositions of the social capital stock in Japan upto 2050. Plausible assumptions indicate that it will be very difficult to construct new social capital stock beyond 2025.
