Generally speaking, Japanese islands are plentiful in annual precipitation
about 1,600 mm in average, however, annual precipitation is different from place
to place and from time to time. Small islands located in the southern part of
Tokyo such as Izu islands and Ogasawara islands, there are primitive rain water
cistern such as Toshima, Shikine-jima, Hachijo-jima and Aogashima.
