Our company was founded in 1946, with the original mission of creating comfortable public spaces through electricity, air, and water. Our primary business operations have been electrical work and equipment installation. Recently, we have been working on energy conservation projects.



In 2011, we received patents in Japan and the U.S. for "Eco-vision," an energy-saving central air conditioning system developed by our company. As of March, 2013, approximately 60 of the units have been installed throughout Japan.



Early models have been in use for almost seven years, and have continued to reduce energy consumption. Investment costs can be recouped in three to five years by facilities such as general hospitals, shopping malls, and hotels where air conditioning is used for relatively long periods of time.

The rate of energy reduction is variable, but it ranges between 65-95%.

Our pumps used for air conditioning are considered to have the best performance in terms of energy conservation in Japan.

We have not yet worked with overseas clients, but are looking forward to doing business in many different countries.

We hope to work with firms in your country too.
