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.


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.



Combining three systems for zoning, ventilation and air purification, SMARTECS keeps air inside the home clean while also controlling temperature.

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 Sekisui House 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.

After-sales service

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.
