Why Penta Ocean Construction?

Penta-Ocean Construction was founded in 1896 as Mizuno-gumi in Kure City, Hiroshima Prefecture, and we recently celebrated the 130th anniversary of the company’s founding. Over a number of decades, our initial marine civil engineering business expanded to land civil engineering and building construction.

Our overseas ventures started with the Suez Canal Dredging Project in 1961, and we have been involved in many milestone projects, mostly based in Singapore, since our first entry into the market in 1964.

A substantial increase in business volume in domestic civil engineering and building construction segments propelled our consolidated net sales beyond the ¥700 billion threshold for the first time in FY 3/25. Our aspiration is to grow and evolve into a company where all three business units contribute to profitability in a well-balanced manner.

The Goal to Aim for – a Genuine Global General Contractor –

Penta-Ocean Construction Group aims to become a “Genuine Global General Contractor” who practices sustainability management. A genuine global general contractor is defined by the absence of barriers among the three business units (Civil Engineering, Building Construction and International), enabling their seamless inter-departmental collaboration.

Moreover, Diversity, Equity and Inclusion (DE&I) are deeply embedded in its corporate culture, and employees of diverse backgrounds can thrive equally and continue growing, regardless of nationality, gender, or field of expertise. Our belief, “The Greatest Contribution to Society is the Construction of High-quality Infrastructure,” is profoundly ingrained in our construction business activities.

Not only do we strive to deliver reliable safety and quality backed by advanced technologies, but we will also earnestly endeavor to tackle all sustainability issues from an ESG perspective, across all aspects of our business. With this conviction, we are committed to fostering sustainable development of society, as a genuine global general contractor with distinctive strengths in port, coastal and waterfront areas and overseas.
