サンエイ Company Profile

Towards the realization of an ideal circular society.

Sun-Ei Co., Ltd. has been dedicated to "improving water environments" since its founding in 1983. In a world largely covered by water, the water environments we can engage with may be just a small part. However, water is not only a resource that supports people's lives but also the origin for all living beings and a treasure of the entire planet. For us, who specialize in the improvement of such "water" environments, it can be said that our mission is to seriously confront water while looking to the future and to devote all our efforts to fulfilling our work. Moreover, fulfilling this mission sincerely can be regarded as our contribution to society and the Earth. As the call for global environmental conservation grows louder, the needs for our services are expected to diversify increasingly, requiring the best technological capabilities, rich creativity, and flexible responsiveness. To meet these significant expectations, Sun-Ei will continue to make efforts to protect water, challenge new endeavors, and strive for comprehensive engineering in water environment improvement.
