Our technical capabilities, construction capabilities and customer base are our greatest strengths.
Our core competencies consist of our three greatest strengths--technical capabilities and construction capabilities driven by Sekisui House technologies, and a solid customer base derived from the industry’s highest number of dwellings built--together with our unique value chain, which maximizes value for customers. These core competencies are the source of the value we create.

The Sekisui House Group handles all processes relating to homebuilding, from product and technology development to sales, design, construction and after-sales service, and aims to provide superior products and services that lead to customer trust and satisfaction.
These strengths have helped us build a strong customer base, boasting the highest cumulative total number of dwellings built in the world.
We also aim to further improve the efficiency of our operations by pursuing initiatives to reduce costs through the integration of development, production and construction.

SHEQAS - Seismic energy absorption system
Sekisui House original earthquake-resistant structures certified by the Japan's Minister of Land, Infrastructure, Transportation and Tourism
Sekisui House’s proprietary SHEQAS seismic control system reduces building movement by converting seismic energy into heat energy, and can reduce building deformation by approximately 50%. Made of special high-damping rubber, the SHEQAS damper maintains its effectiveness even after multiple large earthquakes or aftershocks, providing housing in which residents can continue to live with peace of mind. In fiscal 2019, SHEQAS was used in 97% of the homes we built.
Airkis high-quality indoor system
Reduce indoor concentrations of chemical substances to less than 50% of the guidelines values set by the Japanese government.
Airkis is the Sekisui House original high-quality indoor air system. It reduces indoor concentrations of five major chemical substances to less than 50% of the guideline values set by the Ministry of Health, Labour, and Welfare, assuming that children use about twice as much air as adults. In fiscal 2019, 88% of the steel-frame detached houses built by Sekisui House used the Airkis high-quality indoor air system.
Design-build construction system to guarantee solid construction quality
Design-build construction system through wholly-owned subsidiary Sekiwa Construction companies and Sekisui House Association
Each detached house we build has a unique design and is tailor made for the specific customer, so on-site quality control is a critical process for a successful build. We enter into contracts directly with customers without going through agents and we have established a design-build construction system to ensure reliable construction quality. The wholly owned Sekiwa Construction companies and the Sekisui House Association consisting of building contractor partners promote improvement in the level of skills through training, and thoroughly implement quality control.
Customer Center with a full-time staff of 1,500 employees, roughly 10% of Sekisui House's entire workforce
Appropriate maintenance of the house is needed to make sure residents can live in continued comfort, and Sekisui House considers this maintenance to be part of a home's intrinsic value. This is why we have Customer Centers nationwide. Information about customer housing is also managed on a central company wide system. After moving in, questionnaires and other tools are used to collect customer feedback. This information is distributed throughout the Company and utilized daily as an important source of information for product development and service improvements.
Solid Customer Base
With our highly respected technical and organizational capabilities, Sekisui House has been leading the housing industry for over 50 years in developing housing-related businesses and building a solid customer base boasting the largest number of housing units in the world.
The strength that comes from leveraging our strong customer base and collaboration within the group has helped expand the supplied housing business to meet the changing needs in society, through such segments as the real estate management fees business and remodeling business.
