About the Company
Our mission
Breaking new ground, together
Above all, we value the techniques and wisdom the construction industry has built up over many years, and the ingenuity honed on construction sites.
That is why our aim is not to replace them. It is to combine them with technology and other new approaches, making possible what was long thought difficult and further expanding what construction can do.
To “break new ground” does not mean rejecting what already exists. It means carrying its value forward while forging options no one has seen yet and new norms for construction.
Polyuse cannot take this on alone. Together with clients, contractors, designers, research institutions, partners and everyone involved on site, we pool our knowledge, respect one another and build trust as we co-create a new future for construction.
“Breaking new ground, together” means working with everyone in construction to create the new norm for how we build, and carrying it into the future.
That is our mission.
story 01
Labor shortage
What's lacking isn't just the number of people. It's the gap between regions. Japan's skilled construction workforce shrank from 4.55 million in 1997 to 2.96 million in 2025, and that decline is felt directly in the daily lives of regions that rely on public works.Polyuse One can be run by as few as two people. Crews build to consistent quality without expert skills, so clients get the same quality of structure wherever they order. Evening out construction capacity across the country is exactly what we are working on.*Source: MLIT material based on the MIC Labour Force Survey (2026).
story 02
Aging infrastructure
The infrastructure built during Japan's era of rapid economic growth is now coming due for renewal all at once. By 2040, about 75% of road bridges are expected to be more than 50 years old. There is more to repair, and fewer people to repair it.With 3D-printed construction that sets printed parts in place on site, we shorten construction periods for repair and renewal, and give society more capacity to fix aging infrastructure fast.*Source: MLIT, “Current State and Future of Aging Social Infrastructure.”
story 03
A disaster‑resilient Japan
The government's national resilience initiative aims to build a “strong and flexible nation” that protects lives, minimizes damage and recovers quickly. By turning construction processes that depended on individual skill into work anyone can carry out, we build up that preparedness as fast as it is needed.
A country that can build the infrastructure it needs, anywhere
Our goal is to install 100 Polyuse One machines across Japan by summer 2027, building a network that puts construction 3D printing technology within reach from anywhere in the country.
