Japan Water Agency-Independent Administrative Corporation

Objective and Activities
The Japan Water Agency is an "Independent Administrative Agency" undertaking activities of public interest in an efficient, self-supporting manner by introducing a management style typically found in private businesses.
The Agency, with its management philosophy of "Providing a Stable Supply of Safe, Quality Water" at a reasonable price, is engaged in the construction and refurbishment of major dams for water utilization (for domestic, industrial and agricultural water supply) and river management (flood control, the maintenance and promotion of normal functions of water flow) purposes; estuary barrages; lake and marsh water level controlling facilities; and facilities for the development and utilization of water resources such as channels, and the operation of completed facilities in an integrated manner in the seven river systems designated as river systems for water resources development.
In discharging its responsibilities, the Agency obtains the consent of water users for their contribution to share the cost through conference with the prefectural governors concerned and carries out projects according to project implementation plans approved by the Ministers supervising the Agency under the Water Resources Development Basic Plans.
Since the activities of the Agency have diverse objectives and are carried out in many different fields, four ministers, i.e., the Minister of Land, Infrastructure and Transport, the Minister of Health, Labor and Welfare, the Minister of Agriculture, Forestry and Fisheries and the Minister of Economy, Trade and Industry, are responsible for supervising the Agency.
  1. Areas involved in the water resources development river systems account for about 17% of the total land area or about 51% of the total population of Japan, representing Japan's vital areas for its economy and people's life, where about 46% of the nation's industrial outputs or about 56% of GDP are produced. In those areas, the amount of water developed by the Agency by 2006 was approximately 334 m3/s, which is 88% of the 381 m3/s available in those areas as developed water.
  2. The Agency is the sole comprehensive organization dealing with water in Japan that has the capability to coordinate many water users with different uses, such as domestic, industrial and agricultural water, and scattering over extensive areas involving more than one prefecture, and to carry out projects in an efficient manner.
  3. Having constructed and operated 62 facilities comprising dams and water channels, the Agency has accumulated many advanced technologies for dam and water channel development projects.
  4. Projects are funded with grant money from the National Government for river management projects, subsidies from the National Government for agricultural, domestic and industrial water source development, contributions from water users and loan money.
