Our Foundation
Technology and Trust
At TOA CORPORATION, our identity is shaped by an enduring philosophy that has guided us for over a century: contributing to a prosperous society through construction, grounded in our core values of Technology and Trust. This principle is not merely a slogan, but the foundation of our corporate culture and decision-making.
We believe that true value is created through sincere construction—a commitment to integrity, quality, and high ethical standards in every project we undertake. This sincerity builds lasting trust with clients and communities, enabling us to take on complex and challenging projects worldwide. Under our unwavering Safety First principle, we prioritize the well-being of both people and the environment.
This strong foundation empowers our teams to address societal challenges such as urbanization and climate change, transforming them into opportunities to co-create sustainable value for future generations.
Create Value, Build the Future
What We Build
From the Sea to the Future
TOA CORPORATION delivers a wide range of infrastructure projects that support daily life and economic activity across regions, with marine construction as one of our core strengths. Since our founding, we have played a leading role in developing ports, coastal facilities, and marine infrastructure that form the backbone of logistics, transportation, and energy networks.
Operating in Japan and overseas, TOA undertakes projects in diverse environments, from coastal and offshore sites to a wide range of onshore construction sites. These projects require not only advanced engineering capabilities but also a deep understanding of local conditions, regulations, and stakeholder needs. By working closely with clients, local partners, and communities, we deliver construction solutions that maintain high standards of quality, safety, and reliability.
Through these projects, TOA plays a role in connecting people, regions, and the world—delivering construction solutions that support long-term growth and generate lasting value for society.

Our Approach to Sustainable Construction
In line with Singapore’s 2030 mandate for all new harbor vessels to be electric, biofuel-powered vessels, or net-zero alternatives, TOA is set to deploy electric boats in the Woodlands area as part of its Proposed Coastal Development project. Located near the ecologically sensitive Mandai River and mangrove forests, this initiative aims to minimize environmental impact and conserve the natural environment. This marks the first deployment of electric vessels on a construction site in Singapore, setting a benchmark for sustainable maritime operations.
