Japan s water storage

Water use in Japan developed in close association with the production of rice paddies from ancient times. After rice paddy cultivation was introduced, the construction of small ponds was started, and then, with expansion of the manorial system and later backed by efforts of warring feudal lords to maintain and increase rice production, the use of water from small and medium rivers e.
