President’s message”The Target Mission of JAT”

Since its establishment in 1976, Japan Techno Co., Ltd. (hereinafter referred to as JAT), as a development consultant in the water supply field, has contributed to rural water supply, sanitation improvement, water supply and sewerage improvement and technical cooperation projects in developing countries. The mission aimed by JAT is to “solve problems related to water and the environment on a global scale” and “contribute to world peace through development cooperation”. The achievements from working on water and environmental issues in countries around the world for nearly half a century gives great pleasure. Inclusively, I would like to express my sincere appreciation for the support given to us by our clients and many persons concerned.

According to an announcement by the United Nations, the world population is expected to reach 8.5 billion persons in 2030 and 9.7 billion persons in 2050 from the current 7.7 billion persons. On the other hand, in the SDGs (Sustainable Development Goals) for 2030 of UN, water and sanitation issues are directly or indirectly involved in many of the goals and are most fundamental and essential themes for realization of world peace. This is most closely related to JAT’s business domain, and JAT intends to tackle the demand for water infrastructure requirements around the world with enthusiasm and pride.

I ask for your continued guidance and encouragement.

President      Akihiko UCHIYAMA
