Since rainwater hasn't been recognized as a valuable water
resource in Japan it hasn't been used to its full potential. Our main concern
is the efficient rainwater collection. In the recent past people living in
urban areas suffer from water shortage while occasional heavy rains cause
flooding. A city's water supply usually depends on a far-away source.
One of the solutions to this problem is a rainwater
utilization system using cisterns or seepage pits. These have been popularized
gradually in Japan, mostly equipping public buildings. To make rainwater
collection more standard individuals have to start using it as well. Therefore
some local governments have established financial assistance program for people
equipping their homes with rainwater collection systems.
In this paper, the existing state of financial assistance
differing from one local government to the next is investigated.
