会社について

【About Hiraiwa Construction Co., Ltd.】 ■ What kind of company is it, and when is it needed? Hiraiwa Construction Co., Ltd. is a general construction company that builds essential structures such as public facilities, commercial buildings, office buildings, and residential housing. By designing and constructing buildings that offer safe and comfortable spaces, we support the infrastructure of society. We also respond to evolving needs such as earthquake resistance and barrier-free accessibility. ■ What type of company is it? We are a stable mid-sized company based in Saitama Prefecture, with over 70 years of history. We place importance on being rooted in the local community while steadily building up our technical expertise and trust. At the same time, our company fosters a culture where young employees are encouraged to take on challenges. Many of our younger staff are entrusted with large-scale projects early in their careers, providing an environment where they can experience real growth. Moreover, we do not confine ourselves to being a “traditional regional general contractor.” We continuously evolve, embracing new challenges such as overseas expansion, entry into new business areas, and proactive workplace reform. ■ Where can you work? Our headquarters is located in Tokorozawa City, Saitama Prefecture. Most of our construction projects are based in the Kanto area, primarily in Saitama and Tokyo. ■ Who can apply? We are currently recruiting students who are expected to graduate in 2026 or 2027. ■ Mission: What is the company’s purpose? Looking at things from the customer’s perspective—even more than the customer does. We don’t consider the person placing the construction order to be our only "customer." We also think about the residents or users of a building, or the local community that uses infrastructure like roads. That’s why we believe construction is not only about making things—it’s also about providing a service.

Renovation Work

We provide comprehensive solutions ranging from building longevity and asset value enhancement to energy-saving, labor-saving, and seismic retrofitting.

We handle everything from small repairs to large-scale renovations such as exterior refurbishments and seismic strengthening. We also receive commissions concerning condominiums, tenant buildings, factories, and cultural and educational institutions. We also take on partial upgrades such as HVAC systems, plumbing, roofing, and exterior walls.

With the technical skills we’ve developed over many years, we not only provide appropriate maintenance to preserve building value but also offer proposals to enhance building functionality and efficiency, including construction based on seismic assessments.

Vietnam Construction & Expansion Support

To support Japanese companies expanding into Vietnam, we provide total construction services for factories, warehouses, and offices. With bases in Ho Chi Minh City and Hanoi, we handle projects throughout Vietnam.

By leveraging our experience and success in Japan, we offer high-quality and cost-effective construction services under the concept: “Japanese quality at a lower cost, managed by resident Japanese engineers.”

Our Japanese engineers, experienced in construction both in Japan and Vietnam, are stationed locally. They work closely with local staff to ensure detailed and high-quality project management, maintaining consistent standards.

Compared to major general contractors, we can keep operational costs low, giving us a cost advantage. Our headquarters in Japan fully supports our local subsidiary, HIRAIWA VIETNAM, and the entire company is united in driving our Vietnam business forward.
