Managing Director of the International Division

International Division

YEC is characterized by its strong professionalism and connected team strength, which transcends genres and leverages its advantages as an integrated development consultant. With technological ability as its foundation, YEC makes use of both sensitivity and reason, responding to client requests with devotion to the highest standards and providing services in its role as a dynamic, high quality, and ambitious consultant.

YEC was established in 1963 with the desire to contribute to human society for millennia to come. In the half century since then, YEC has continued to advance its purpose and has grown to have multiple integrated development consultants within Japan. In 1991, International Division was established for the purpose of strengthening overseas operations.

The International Division consists of a project promotion office, which cooperates with overseas offices, such as Jakarta and Myanmar, as well as local departments, and plays a proactive role in the organization. It is centered on the Business Management and Marketing Department and the five technical departments (Social and Economic Infrastructure Department, Water Resources Department, Urban Environment System Department, Utility Planning Department, and Electric Power System and Plant Department).

The division already has achievements in development projects such as infrastructure improvement in over 100 countries and regions, including in Asia, Africa, the Middle East, Latin America, and the South Pacific. Additionally, it actively takes part in projects that support peacebuilding and peace restoration worldwide, taking pride in its role as a company that contributes on a global scale.

Capitalizing on the results it has so far achieved, YEC will continue to tackle infrastructure improvement projects using ODA for water resources, disaster prevention, water supply and sewage systems, waste management, electricity, broadcasting and communications, roads and transport, and so on. At the same time, YEC will proceed with a focus on new fields, such as smart communities, rebuilding assistance after natural disasters, such as earthquakes, tsunamis and cyclones, and new business models like PPP.

Currently there are many problems that need to be addressed, including global issues such as natural disasters, poverty, global warming, biodiversity and infrastructure development in emerging nations. YEC, which is engaged in many technical fields, is able to flexibly accept and address the challenges of complex and difficult multi-sector projects using its comprehensive abilities. In addition to advanced technological skills, YEC approaches projects with the Japanese spirit of harmony and consideration for others and contributes to global stability and development.

Our challenge will contribute to disaster mitigation and Water Resource Development.

Takeshi Watanabe
Water Resources Department, International Division

Water Resources

There are growing concerns about the future of the earth’s water resources due to increasing demand and global warming, partially a result of the global population increase and industrialization of emerging economies. Meanwhile, the Earth’s water resources are unevenly distributed, and countries without access to safe water are concentrated mainly in Africa and Asia. Sources and methods of exploiting water resources include rivers, groundwater, desalination, and recycled water, and there is a need to make better use of recyclable water resources at an economically viable cost and to consider sustainable water consumption.

In the field of water resources, YEC’s overseas consulting businesses handle large-scale projects, sometimes extending to development planning, detailed design, and the construction management of entire catchment areas or countries. The progress and results of this work are largely determined by the abilities of the consulting personnel, the conditions in and availability of information about the target country, and the abilities of the local staff. To contribute to the development of water resources in developing countries, YEC capitalizes on the knowledge and experience gained through its numerous project accomplishments.

Disaster Risk Management

It has been pointed out that in order to systematically improve responsiveness to natural disasters, it is important to develop and strengthen organizations, arrangements, and capabilities at the community level. In particular, because of poor warning systems and the lack of escape routes and shelters at the community level in developing countries, information on disasters such as earthquakes and tsunamis is not transmitted to residents quickly or accurately. Additionally, there are situations where it is difficult to properly carry out emergency aid. As such, there is a need to strengthen the disaster prevention capabilities of inhabitants. Meanwhile, deforestation in upstream areas, agricultural development and urbanization have advanced in recent years, and landslides into dams and reservoirs have increased. As such, there is a critical need for long-term, comprehensive landslide management incorporating both upstream and downstream areas.

In addition to yen loan projects in the above fields, YEC also engages in technical cooperation for grant projects in the above fields in Southeast Asia, the Middle East, Africa, and South America.

Losses and damages from natural disasters are growing, both in developed and developing countries, and the role of overseas consulting in the field of disaster prevention has become extremely important. Based on the advanced expert knowledge of our specialists, plans for national development are being drafted and implemented, particularly in developing countries, with the aim of constructing societies able to withstand natural disasters. Our company sees great value in completing difficult projects through cooperation with the governments of various countries and regional inhabitants, including the poor, as a consulting business from Japan, a country with significant experience with natural disasters. To the best of our ability, we will continue undertaking projects that capitalize on the disaster know-how of our country and the expert knowledge of our personnel.

Realizing Safe and Reliable Utilities for Urban Environment and Recycling-based Societies

Katsumi Fujii
Urban Environment System Department, International Division

Water Supply & Sewerage

In Japan, we can get plenty of water just by opening a faucet. However, there are many regions in the world where the infrastructure to access safe and reliable drinking water has yet to be developed. Unfortunately, many people in such regions suffer from water-related diseases, which can be fatal. Moreover, the development of sewage systems and sewage treatment is even more delayed than that of water supply systems. Water pollution is serious, with black sewage water being used for irrigation and untreated water posing a threat to drinking water resources. Throughout the world, there are regions that don’t even have toilets, where inadequate hygiene education affects people’s health.

We suggest methods for the delivery of safe and reliable drinking water and for efficient sanitary sewage treatment to people around the world and provide support (planning, designing, and construction supervision) for the development of necessary facilities. We also give instructions related to hygiene education and the improvement of operations of water supply and sewerage systems and human waste and effluent treatment. We support water sanitation and hygiene in developing countries in both tangible and intangible aspects.

Solid Waste Management

Garbage trucks, garbage incineration plants, and final disposal sites are taken for granted in Japan but that’s not the case in every country in the world. There are areas where garbage is strewn everywhere in towns and where garbage left in open spaces spontaneously combusts. Needless to say, if the garbage is left out, it causes not only vermination but also spreads diseases.

Garbage is said to be a “mirror of society.” We study the characteristics of garbage, which differ according to social environment, climate, and lifestyle, and suggest a mechanism for collecting and treating garbage that is optimal for each area or lifestyle. We also provide support (planning, designing, and construction supervision) to improve the necessary equipment and facilities, such as garbage trucks, recycling centers, and final disposal sites. The concept of the 3Rs (Reduce, Reuse, and Recycle) has spread all over the world. However, we need to take time to educate the public. The provision of related technical assistance is one of our important jobs.

Delivering electricity to everyone

Kyoji Fujii
Electric Power System and Plant Department, International Division

Electric Power System and Plant

Electricity powers our modern lifestyles and is indispensable to economic development and manufacturing growth. However, there are still many countries where only about a tenth of the citizens have access to electricity, and other countries where frequent power outages are a major concern. YEC’s Electric Plant Division supports the stable supply of electricity in developing countries throughout the world, starting with Africa, and contributes to the establishment of peace, the improvement of living conditions, and economic revitalization. The division has also sped the introduction of renewable energy sources, such as solar power, and microgrid systems that combine renewable energy and electricity storage facilities in the Pacific Island States. This has helped reduce greenhouse gas emissions, global warming, and power generation costs.

Let's think about the social infrastructure development togethers

Kazuo Iwai
Social and Economic Infrastructure Department, International Division

Urban Development / Regional Development

The main societal issues in developing countries are poverty reduction and peacebuilding.
To solve these problems while also maintaining respect for the opinions of the people of developing countries, the department takes into account the personal, organizational, and systemic/societal levels of each country when engaging in various projects, such as capacity development, and supports cooperation that enables self-help and self-reliance.

Furthermore, to improve developing countries economically, socially, and culturally, it is necessary to concretely examine those countries’ infrastructures, industrial development, social systems, etc., based on the distinctive features of their cities or regions. These must be coordinated to engage in systematic urban planning and regional development. To realize the visions of the future that developing countries seek, the department supports plan implementation and uses both hardware and software to carry out technological migration for stakeholders, such as governmental institutions and citizens, using concrete drafting techniques for local development strategies and planning.

PPP/Industrial Development and Promotion

This is an age with a rising global need for social and economic infrastructure development, particularly in emerging economies demonstrating remarkable growth. Therefore, it is crucial that we aim for the establishment of local infrastructure and industrial development, while maximizing resources, such as capital, technology, products, and industrial know-how, in both the private and public sectors.

Starting with feasibility studies on the commercialization of public facilities and infrastructure development using PPP (Public-Private Partnership), which taps into the capital and know-how of the private sector, we carry out initiatives aimed at realizing development projects coordinated with governments and people.

Additionally, in developing and emerging countries, we carry out projects using a business model that includes provisions for the poor, implementing regional development plans that capitalize on local industrial features, promote local products, and support the expansion of BOP (bottom of the economic pyramid) businesses. The objectives are to improve the quality of life for citizens, including the poor, and reduce socioeconomic disparity.

Road / Bridge / Transport / Railways

Roads and railways are the most basic form of social capital, being essential to the transport of goods and the movement of people, and are thus indispensable to balanced national development and the development of national economies. However, the inadequacy of actual road and railway networks and the poor operation and maintenance of existing infrastructure continue to pose problems for developing countries.

We survey the current conditions of the transportation and social infrastructures of developing countries, identify the issues target countries and regions face, and contribute to the creation of a master plan enabling efforts for future needs. Whether supervising the design and construction of road and railway infrastructure or studying local construction technologies and construction work safety management, we work with local stakeholders to tackle project initiatives. In the case of particularly unstable countries, we carry out research and design through remote management, using a third country as a base.

By supporting capacity development for local stakeholders to operate and manage facilities independently, we enable the continuous maintenance of facilities provided under ODA, and thus play an important role in these aspects as well.

Providing opportunity to make a better life for the world

Kiyofusa Tanaka
Utility Planning Department, International Division

Broadcasting & Communication

The history of YEC’s advance into the field of broadcasting began with a comprehensive development planning survey for radio and television broadcasting in Indonesia, conducted in 1990. Since then, YEC has achieved results in the broadcasting field on a global scale, from rehabilitating television stations following the defeat of the Taliban in Afghanistan to the renewal of medium wave radio facilities in Nigeria and Tuvalu. With Japan’s advances in technology, the Information Technology and Communication Section has also engaged in planning for terrestrial digital broadcasting and has proposed courses of action and plans for the transition to digital broadcasting in various countries, such as Ecuador, Paraguay, such as Ecuador, Paraguay, Sri Lanka, Maldives as well as Botswana. Additionally, the department has also crafted proposals for an Early Disaster Warning System using terrestrial digital broadcasting in Peru, and there are expectations for a global strategy merging YEC’s disaster prevention technology with its communications technology.

Architecture

The Public Facility Section began with the design of an Algerian cement factory in 1975. Following this, it started receiving orders from developing countries like Nigeria for the construction of primary schools. The department also carried out the construction of the Valley of the Kings visitor center in Egypt, in addition to preparing construction plans for government office buildings in the Maldives and for post-disaster and tsunami reconstruction support. Recently, against the background of Japanese industrial technology, the department has also had a hand in constructing facilities as well as genuine, reliable architecture. In particular, at the Bandung Institute of Technology, which is currently under construction, design plans for experiment and training facilities that include advanced research equipment are being implemented. On both the Public Facility Section's side and the Indonesian side, it is anticipated that these plans will enable the creation of university facilities equipped with incubator functions.
