It is a rock-fill dam with a central impervious core constructed on the Masutani River in the Kuzuryu River system, mainly for agricultural use but also for water supply, industrial use, and flood control. This dam is one of the largest agricultural engineering projects in Japan and is the culmination of our expertise in fill dam design. For more than 20 years leading up to its completion, we provided comprehensive consulting services ranging from project planning and basic surveys to basic design, detailed design, and technical support during construction.
Shotaro Kuno (our first president) and others launched the Aichi Irrigation Project to alleviate water shortages in the Chita Peninsula. 112 km of main canals, 1,012 km of branch canals, and the Makio Dam were constructed as a national project. In the project's second phase, we were involved in the design of the canals, bypass tunnels, etc., and designed the canals with consideration for harmony with urban areas. We were also in charge of sediment control measures for the Makio Dam.

This is a movable weir with a weir length of 220m, constructed on the Yasu River, a first-class river flowing into Lake Biwa, to prevent disasters caused by flooding, maintain agricultural productivity, and stabilize agricultural management. The four Inflatable rubber gates used for the flood discharge are one of the largest in Japan. Fishways were also adopted to facilitate the movement of fish inhabiting the Yasu River. We participated in the project from the conceptualization stage and were in charge of the basic design and detailed design.

International Business
We contribute to peace and prosperity in the international community. We extend a helping hand to those seeking a better tomorrow.
As a reliable partner to developing countries, we strive to address challenges through development cooperation based on three pillars: nation-building, infrastructure and industrial development, and human resource development. We are committed to building a better international environment primarily through Official Development Assistance (ODA) projects, development assistance policies for developing countries, and measures to reduce economic disparities.
In Mindanao, the Integrated Rural Development Project was implemented with the following main components to reduce poverty and achieve sustainable development in settled areas left out of development for many years due to inadequate support.
1. Infrastructure development (irrigation, water supply, roads, etc.)
2. Agriculture/environmental conservation (agricultural productivity improvement, livestock, and forestry development)
3. Organisational development

Rwanda is one of the most densely populated countries in Africa and one of the poorest countries in the world. In addition to improving the severe food shortages, an action plan for agricultural and rural development was developed to enhance livelihoods and improve the lives of people experiencing poverty by improving hillside farming techniques, soil conservation, wetland development, etc.

Rehabilitation of Gates of Taunsa Barrage
[Pakistan]
Situated on the Indus River, the Taunsa barrage has played an essential role as the backbone of the Indus irrigation system, supplying irrigation water and supporting the development of roads, railways, and pipelines. However, the weir has deteriorated considerably in the 45 years since its construction. We carried out a design study to restore the weir's functionality, and a rehabilitation project was implemented with grant funding.
