Four Key Values and the SDGs
Promoting sustainable management through our Four Key Values under our philosophy of “Love of Humanity”
Our Sustainability Vision, which we adopted in 2005 and which comprises our Four Key Values and 13 Guidelines, continues to serve as the basis of our approach to value creation. At the root of this is the mindset and the roles we have demonstrated throughout our 60 years of history. These include promoting lifelong contentment, protecting the life and property of our customers, protecting the global environment, and conserving the ecosystem. These are beliefs we continue to support.
Corporate Philosophy (fundamentally, “love of humanity”)

At the core of the Sekisui House Group's corporate philosophy is a love of humanity: recognizing the irreplaceable value in each and every person, we maintain a fervent hope for the wellbeing of others and a sense of joy in others' joy, doing whatever we do in good faith and a spirit of service. This philosophy took root in 1989 with the unanimous approval of every group employee.
Four Key Values and 13 Guidelines
In 2005, we announced our Sustainable Vision targeting balanced management based on four key values that focus on sustainability as the cornerstone of our management. In 2006, we formulated 13 guidelines as guiding principles based on these four key values.
Four Key Values, 13 Guidelines and the SDGs (Direct and indirect contributions through our businesses)
The Sekisui House Group declared its Sustainability Vision 10 years before the United Nations adopted its sustainable development goals, or SDGs. The SDGs were adopted in 2015 as common objectives of the international community in terms of maintaining the health of society, the economy, and the environment. Since establishing its Four Key Values and 13 Guidelines in its Sustainability Vision, our group has taken a direct approach to pioneering and implementing sustainability.
Many expect that, going forward, social issues will become more complex and increasingly global in nature. To address these issues, we are placing ever greater emphasis on implementing the SDGs and targeting “Society 5.0,” which is a vision of an optimized future society utilizing the Internet of Things (IoT) and artificial intelligence (AI).
We remain committed to enhancing our corporate value and contributing to the achievement of the SDGs through our business with diligence and a spirit of innovation.
