Building on Three Pillars — How Sekisui House Integrates Innovation, Sustainability, and Global Expansion
At Cadira, we place importance not only on regular IR meetings but also on engaging directly with companies through on-site visits and dialogue. Recently, we had the opportunity to tour three key facilities of Sekisui House: the Eco-First Park, Tomorrow’s Life Museum Kanto, and the Kanto Factory. Below is a brief summary of our visit.
This visit offered valuable insight into the company’s environmental technologies, residential design innovations, and production systems. We were also able to gain a glimpse of Sekisui House’s strategic expansion into the U.S. market. It was an opportunity to witness firsthand how the company integrates technological innovation, environmental commitment, and global expansion as the three pillars of its corporate value creation.
Our first stop was the Eco-First Park in Koga City, Ibaraki Prefecture, a 30,000-square-meter environmental education facility showcasing Sekisui House’s sustainability initiatives. This park exemplifies the company’s philosophy of “changing society through housing,” allowing visitors to experience and understand its environmental practices through interactive learning.
The tour featured explanations on the sorting and processing of construction waste, utilization of renewable energy, biodiversity-conscious landscaping, and environmentally advanced model homes. Each new home generates about 1.5 tons of construction waste, which is transported to this facility and sorted into 27 categories, some of which are further processed through automated crushing systems.
Although certain materials such as PVC incur high processing costs, Sekisui House is aiming to raise its material recycling rate from 80% to 90%. These efforts not only contribute to environmental outcomes but also strengthen brand value and social trust. The company is working collaboratively with materials manufacturers and leveraging IT systems to manage waste more efficiently, illustrating a clear focus on balancing sustainability and operational efficiency.
Next, we visited the Tomorrow’s Life Museum Kanto, an interactive residential exhibit designed as a “housing theme park” where families can explore ideas for future living. One highlight was Shawood, Sekisui House’s signature wooden housing brand.
The design process has shifted from traditional “intuition and experience” toward science-based engineering, allowing for larger open spaces, Net Zero Energy House (ZEH) compatibility, and the combined use of engineered timber and MJ metal connectors to deliver both structural strength and aesthetic design. Each Shawood home is custom-built, with features like tile-shaped solar panels that harmonize functionality with visual appeal.
Our final stop was the Kanto Factory. Despite being over 50 years old, the facility has undergone significant automation and is actively meeting strong demand for both steel-framed and wooden homes. Components are managed individually for each home, and the final assembly is completed with careful human inspection and craftsmanship—demonstrating a deep commitment to quality.
The factory also serves as an export base for Shawood materials bound for the U.S., highlighting Sekisui House’s ambitions for overseas growth. The company currently delivers about 15,000 homes annually in the U.S., primarily using the 2×4 construction method. However, it plans to expand Shawood sales to 3,000 homes per year by 2031.
While the U.S. market tends to place less emphasis on earthquake resilience, resulting in concerns about over-specification and pricing, product differentiation is progressing, and initial market responses have been positive.
That said, Sekisui House’s environmental messaging—such as resource circulation, zero emissions, and the "Gohon no Ki" landscaping initiative—has yet to fully resonate with U.S. consumers. Instead, priorities like power outage resilience and compatibility with central air conditioning are currently more persuasive. Whether environmental awareness will grow in the U.S. remains to be seen.
Overall, this site visit reinforced our impression that Sekisui House is far more than a conventional homebuilder. Its core strengths lie in the depth of its technological expertise, its robust design infrastructure—including a team of 1,500 first-class architects—and its precise on-site execution capabilities. Equally impressive were the company’s advanced and practical environmental initiatives, including thorough waste sorting and biodiversity-conscious planning, which are integral to its reputation and brand equity. Sekisui House’s aspiration to “export its model” and drive growth—particularly in the U.S.—signals a bold strategic ambition, and we look forward to continuing our dialogue with the company going forward.
