Message from the president
Japan Water Agency (JWA) is a public organization with the crucial mission of ensuring a stable supply of water, which is indispensable for the lives and socio-economic activities of the Japanese people, and protecting the lives and property from water-related disasters. It is a "group of water professionals" equipped with advanced technologies and expertise to manage the entire water network, from upstream water source facilities to the waterway networks in the middle and lower reaches, in an integrated and wide-area manner.
For over 60 years, from the days of our predecessor, the Water Resources Development Public Corporation, JWA has constructed and managed water resource development facilities in seven river systems that are vital to the lives of more than half of Japan's population. Through the stable supply of water to major metropolitan areas such as the Tokyo, Chubu, and Kinki regions, it has contributed to improving people’s lives and the development of Japan's industrial economy.
In recent years, the risk of hydro-meteorological disasters due to climate change has been increasing year by year, and water-related disasters occur throughout the country almost every year. The situation facing JWA is becoming increasingly challenging, including responses to such large-scale natural disasters, preparations for major earthquakes, and measures to address the aging of facilities.
Under such circumstances, we have implemented various measures in line with the times. These include the launch of centralizing operations and ensuring flexible operational management including during disaster response. Furthermore, we have formulated a new environmental policy based on recent trends in Japan's environmental policies and JWA's past initiatives.
JWA leverages its accumulated expertise in the construction and management of water resource development facilities such as dams and irrigation canals, as well as in the development and utilization of water resources, including total water resource management, to promote integrated water resource management (IWRM) in overseas, improve water resource development and management capabilities in countries around the world, and is aiming to contribute to disaster prevention and mitigation. As the risks associated with climate change increase globally, we believe that the knowledge and experience of JWA, as a "group of water professionals," would greatly contribute to reducing the risks of water-related disasters and achieve SDGs. Thank you.
