[Company strength]
We provide total solutions corresponding to plumbing facility construction and overall maintenance thereof. The solutions range from pinpoint solutions for each problem to large-scale repair, including countermeasures against deterioration of water-supply piping as well as improvements of the water environment by water modification. We can provide one-stop services for solutions ranging from inspection/diagnosis, repair work, regular maintenance, and transportation of specially controlled industrial waste, which are normally handled by a plurality of specialized companies. We have undertaken more than 140,000 projects in a wide range of fields including ordinary households, buildings, factories, medical institutions, and educational institutions.


[Business description]
We have been engaged in construction and maintenance of plumbing facilities for over 100 years/3 generations since our founding in 1909 (Meiji-era 42). We have undertaken more than 140,000 projects. Our fundamentals lie in a corporate spirit that encourages us to keep sincerely facing up to the wellness of "city, water, and life". Under this corporate spirit, at the beginning of the 21st century, we set our business goal as “restore the water environment”. We are transforming our business into a water environment total engineering business. Today, buildings throughout Japan need to be renewed. Therefore, we are working day and night providing countermeasures against red rust, red water and scale, which we recognize as important issues to be solved.

[Representative's message]
Our company aims to flourish and evolve together with customers and society as a trinity, through our water environment total engineering business. Needless to say, the starting point that defines overall standards in every value is based on "only life existing here at this moment". We will continue our corporate actions in order to make the water environment better for the sake of “only life existing here at this moment”. We will keep walking on the road of self-accomplishment through our daily tasks, by trying to make today better than yesterday, and further, trying to make tomorrow better than today.  We will keep striving for the future with the hope that our everyday efforts eventually promote the self-evolution of every person who engages in our business mission. 


[Company structure for market development/overseas expansion]
People’s requirements for coping with environmental problems are increasing year by year. Moreover, the performance of the water supply and sewerage systems constructed during the period of high economic growth is deteriorating more than ever. We have been actively developing our own new construction methods, products having water purification functions as well as water purification materials, such as “The Bio Water” and an urolith removing agent. Our product, “The Bio Water” provides a countermeasure against red rust, red water and scale simply by being set in a water pipe. We will continue our efforts to solve various problems relating to “water”. Furthermore, we are engaging in research and development for effective river water purification and so on with research institutions such as universities. With such efforts, we will continue working on difficult “water” problems that can be solved only by our original method.
