Management Philosophy

Contribute to help, create and maintain a safe and secure society

Message from President

The Basic Act on Sport states in its preamble that “sport plays an important role in maintaining and improving physical and mental health and is indispensable for realizing a healthy, vibrant, and long-lived society.”

Swimming is an effective sport for both aerobic exercise and strength training. Thanks to the buoyancy of water, it places less strain on joints such as the knees, reducing the risk of injury, and it also offers relaxation benefits. Swimming is a method of maintaining and improving health that can be enjoyed by people of all ages, from children to the elderly.

Aqua Product is primarily engaged in the design and construction of swimming pools, as well as the design and installation of pool filtration systems and wastewater treatment facilities. Our pools and filtration systems are used in schools, public facilities, hotels, and condominiums, playing an important role in supporting the physical and mental health and well-being of local communities.

As a member of the Nippon Filcon Group, we strive to realize our management philosophy of “contributing to the creation and maintenance of a healthy, safe, and secure society,” thereby delivering value to our stakeholders.
