Greeting

Since 1951, when we became the first company in Japan to commercialize prestressed concrete (PC) technology, our group has consistently advanced technological innovation and quality excellence. Through these efforts, we have contributed to the development of social infrastructure and urban environments across both the civil engineering and building construction sectors.

Leveraging the PC technology we have cultivated over our long history, together with the collective strength of our nationwide manufacturing plants and group companies that provide optimal equipment and materials, we have established a unique value proposition as a general contractor. This integrated capability represents a significant advantage that underpins our business foundation.
In our current “Mid-Term Management Plan 2025,” we have defined the following long-term vision:
“Contributing to the realization of an environmentally friendly, safe, and comfortable society through advanced technological capabilities.”
Based on this vision, we have set forth five fundamental policies. These policies guide the strategies we must pursue over the medium to long term as we strive for sustainable growth.
This management plan serves as a vital roadmap for our group as we move forward in a rapidly changing society and business environment, where predicting the future has become increasingly difficult. The driving force behind our sustainable growth is without question, the capabilities of each and every employee. Upholding our core belief that “Safety and quality are the foundation of our company,” we remain committed to executing the fundamentals with absolute certainty, honing our technical skills, embracing challenges, and continuing to approach manufacturing with sincerity and integrity.
We will continue to value the trust of all our stakeholders and, together, create new value while contributing to the realization of a sustainable society.
