We plan flood and water resources management and nature rehabilitation projects to create safe and sound riverswith healthy and sustainable ecosystem.

In various parts of Japan, many severe natural disasters have resulted from recent typhoons and localized rainstorms. With our extensive experience and technologies in river planning, we are working to develop flood control plans and information sharing systems to protect people from natural disasters and to create a disaster-resistant country. We are also working on creating sound water cycle in existing and new river systems that will promote a healthy ecosystem and allow people to relax and engage with nature.
