Message from the President

“We originate value through integrity between human and technology and contribute to the establishment of the position of construction management as well as the growth of the construction industry."

AQA Inc. was established in 1998 as an independent firm specializing in project management (PM), construction management (CM) and quantity surveying (QS) consultancy. Since then, AQA has been a leader in the construction consultancy services, aiming to contribute to the healthy development of the construction sector in Japan.

Over the years, we have overcome economic downturns and industry restructuring, proving our value as a reputable and dependable corporation. Thanks to the trust and support of our valued customers and business partners, we have successfully completed a wide variety of projects and are proud to celebrate our 28th anniversary this year. We extend our sincere gratitude to everyone who has supported us along the way.

The recent construction industry faces a variety of challenges, including skyrocketing prices, new regulations on overtime caps, quality concerns, and workforce shortages. In the long history of the construction industry, the common practice to rely on general contractors’ capability, rooted in the master builder culture that has been in place since the late Middle Ages along with the customary lumpsum contract tendency which was established by the legal framework enacted more than half a century ago, has played a major role. However, as time goes on, the traditional system relying heavily on general contractors’ capability is collapsing due to changes in societal values and diversification of transaction formats.　At AQA Inc., we see these changes as new business opportunities to provide new value by offering expert consulting solutions that address these emerging challenges.

As we enter our 28th fiscal term in November 2024, we are committed to evolve to the next stage of growth through a new mid-term strategy and take steady steps toward the future. Guided by our core philosophy " We originate value through integrity between human and technology and contribute to the establishment of the position of construction management as well as the growth of the construction industry." we will continue to strengthen our position as a unique and trusted firm. Together with our partners, we look forward to shaping a brighter future for Japan’s construction industry.

Norihiro Sagara,
President & Representative Director
AQA Inc.
