Message from the president
We are making every endeavor to meet with the expectations of people as a team of professionals in water business.

For over 60 years, since its predecessor, Water Resources Development Public Corporation, we have constructed and managed water resource development facilities in seven river basins that support the lives of more than half of the national population. Through the stable supply of water to major metropolitan areas such as the Tokyo, Chubu, and Kinki areas, we have contributed to the improvement of the quality of life of the Japanese people and the development of the national industry and economy.
In recent years, we have been facing mounting challenges to fulfill our mission and role due to increasing meteorological risks, including droughts and extreme floods caused by climate change. Other pressing issues include the pursuit of carbon neutrality to address global warming, preparedness for large-scale earthquakes, and the urgent need to take measures against aging facilities.
To address these challenges, we are implementing training programs in advanced dam operation technologies utilizing ensemble rainfall forecasting. Furthermore, from fiscal year 2025, our branch offices will be reorganized into comprehensive management offices to ensure more functional operations, including during disaster response.
Japan Water Agency will continue to demonstrate its unique strengths and contribute to society in playing a role in integrated water basin management by improving operational efficiency and maintaining and enhancing our cultivated technologies as a "team of professionals in water business".
