About Us

Introducing an overview of KEI aiming to gain further recognition and
trust from donor agencies such as developing country governments and JICA.

Message from President

On May 1, 1987, Katahira & Engineers International (KEI) was established mainly to contribute to the socioeconomic development and growth of developing countries.

With its highly dedicated professional staff, KEI has since gained worldwide recognition as an effective consultant for successfully implementing international development projects.

In the past 35 years, KEI has been in the forefront of the implementation and completion of more than 900 JICA ODA grant aid, and other foreign assisted development projects in some 60 countries world-wide, where it provided consultancy services for equipment management, business sustainability, technology transfer, detailed design, construction supervision, etc. in a wide variety of disciplines. Over the years, KEI has received high competence ratings as the consultant of successfully completed projects from various donor agencies including ADB, the World Bank and JICA, and has also received appreciation from the governments of satisfied recipient countries.

KEI has thus gained substantial experience and capability to cope with complex challenges in project implementation. The completed projects have helped in achieving peace in places of conflict, promoting poverty reduction, improving the environment, and enhancing overall socio-economic development in all the countries involved. KEI looks forward to a continued involvement in subsequent donor assisted projects particularly with JICA ODA assisted projects, and offers its assurance of the same high level of consultant professionalism and proficiency.

JICA ODA assistance (include OECF & JBIC) has greatly enhanced the socio-economic conditions of numerous developing countries over 35 years. It is hoped that such assistance will continue for many more years to come and in a greater number of developing countries in the world.

In the past several years, donor agencies and the governments of developing countries have been investigating opportunities to engage the private sector in helping to meet infrastructure development needs. In response to these new challenges, KEI has broadened its services to address solutions for Public-Private-Partnership PPP) schemes and for Built-Operation-Transfer (BOT) projects, and already has acquired experience in this area in Egypt, Indonesia, Vietnam, and Philippines. KEI has a firm foundation and a clear mission to exert our best efforts in order to contribute to the continuing progress of developing countries.
