Company Profile


World Suiko Representative Director Yasuharu Go


  1. "World Suiko" is a company where every people put their effort and wisdom for the realization of rich livable environment by providing water treatment technologies.
  2. We seek balanced development of human and natural harmony through "water" for our society, including the global environment, and explore true happiness of life as a human being.
  3. We focus on the growth of the individual and honor their hard work, assistance to others to establish social enterprises. This will contribute to society through the development of business.

Based on these principles, our company has been founded.

Due to globalization, the distance between people has been shortened and closeness has been maintained yet I feel individuality is becoming rare. Everyone is privileged to have a happy life but in reality it is not.

If we think in the large frame of this world, human life is merely a small thing, however, peer group with the same aspirations, diligence if continues to work together, I believe we could to protect one aspect of mother nature through water treatment approach.

"We care about the health of the Earth."

As always, we look forward to your continued support in future too.
