Recently in the urban area such as Tokyo, people suffer from water shortage while heavy rains cause flooding. It is because of both facts that city water supply is depend on the source far from urban area and that rainwater can not penetrate underground so that most of ground surface has been paved with asphalt. One of the solutions to this problem is the rainwater catchment system such as rainwater storage or rainwater-permeation facilities. Although they have been popularized gradually in Japan, mainly large scale ones have been installed school buildings and public ones, etc. It is clear that their effect becomes even stronger as the rainwater catchment systems installed increase. For more increase in them, it is necessary that the rainwater catchment system will be widely used by an individual. Some local governments have built financial support systems that help an individual install his house. In this paper, the existing state of financial support systems on WWW that differ from each local government is investigated.
