Water shortage is a real and immediate global challenge!
For all living things on this Earth, water is an essential material. All lives, human race, animal, plants, require water (freshwater) to live and prosper. It is needed not only to sustain life, but it is an essential material for civilization.
But in addition to increased intake by population growth with the development of modern civilization, the disappearance of glaciers due to global warming, depletion of lakes and rivers, desertification is compounding the shortage. It is not an exaggeration to say the situation surrounding freshwater is a real and immediate world wide crisis.
There are variety of methods to obtain fresh water, but we are committed to contribute to the world with the environmentally friendly “Atmospheric Desalination ” method.
►About the global water resources
History and Development of establishment
In 1999, UN reports touched on the global water shortage crisis. “What can I do to help?” is the basic desire that started this research.
- There are various means of intake, but we concluded that it is the best to produce fresh water directly from the atmosphere. With the cooperation from Ibaraki University, “Atmospheric water production” research started.
- During this study, we found a way to efficiently produce fresh water from the atmosphere. We obtained a patent filed in December 2008. ►Intellectual property right
- Based on various data collected from our experimental machines, feasibility of this method was established. At this point, we establish a company to carry on the feasibility prospect.
Commercialization Plan

Hideya Koshiyama
- Water, like agricultural product, it is important to produce water at the site where it is needed.
- We will provide to the world a desalination unit that can produce ” inexpensively, anywhere, anytime to anyone.”
- Key component of the machine will be domestically produced in Japan, and other required peripheral equipment will be produced / acquired and assembled locally where it’s needed.
We look forward to working with the local entities as partners in or near the area of demand. - We are seeking business partners in the area of demand.
