Have a lifelong relationship through housing
--Aiming to be one and only company for customers--

Our motto is to have a lifelong relationship through housing, since we hope those who have become our customer to be a fan of us through the home their family is living in, as well as the building for many years, not only by themselves but down to posterity.

We continue to go ahead of the times with our housing and provide homes that customers require. Our relationship with customers will not end when we close a deal. We will develop a lifelong relationship from new construction through after-sales maintenance to renovation. With the aim of becoming a company that customers will thank, we will contribute to them for a better environment to live and enriched life.

Moreover, we consider that improvement in both hardware and software is important for us to realize our philosophy of a lifelong relationship. Hardware is quality of our product. Software is our service. By continuously providing intangible value, i.e., satisfaction, even after the completion of the house, we will strive to enhance customer satisfaction.

Seiyo Housing will develop products that enable us to accurately respond to the needs of the community and customers and will carefully and sincerely address customers’ questions and relieve their anxiety, aiming to be one and only community-based company for customers by providing high quality housing and homes.
