What is Pacific Consultants Group?
Pacific Consultants Group is a corporate group centered around Pacific Consultants Co., Ltd., and is a social infrastructure service group that comprehensively handles everything from infrastructure planning and design to implementation and operation.
Our group's history began in 1951 with the founding of our company in the United States through the collaboration of Japanese and American engineers, and in 1954, our Japanese subsidiary, Pacific Consultants Co., Ltd., was established. Since then, centered around this company, we have been involved in infrastructure development and urban planning both domestically and internationally, including roads, bridges, ports, airports, and water and sewage systems, for over 75 years, leading the construction consulting industry.
Subsequently, with the aim of promoting the group's overall strategy, Pacific Consultants Holdings Co., Ltd., a pure holding company, established in January 2026, and under this new structure, the company is aiming for medium- to long-term growth.
Currently, our group has 16 operating companies across seven business areas. We operate in a wide range of infrastructure service areas, including our core construction consulting business, international business, public-private partnership business, energy business, asset management business, digital and IT services business, and business support business.
Pacific Consultants Group is committed "to realize an affluent life without disparity, where no one in the world is threatened", and "to protect our beautiful planet, the source of all life, and its environment, and passing it on to future generations." By combining the power of people and technology, we will continue to propose infrastructure solutions that are appropriate for the coming era, as a partner that grows together with society.
Group Strengths
The strength of Pacific Consultants Group lies in its ability to provide consistent support from conception to implementation, spanning diverse areas related to infrastructure. By combining expertise across seven business areas and co-creating with stakeholders that support society, we can address complex issues that cannot be grasped individually, from an integrated perspective.
What we value most is the ability to continuously connect the "visionary power" to envision the society of the future with the "implementation power" to turn that vision into reality. In this process, we collaborate with stakeholders who possess diverse expertise and knowledge, integrating a variety of values. Amidst the rapidly changing environment surrounding society and our customers, we grasp the essence of challenges, envision the value that lies beyond, and deliver concrete services to society in various fields such as infrastructure development, community building, energy, and digital. Our defining characteristic is our consistent involvement as a group in this process.
Our field of work is not limited to the public sector. While expanding to private companies and international projects, we continue to create new value by confronting the very nature of people's lives and society.
It's not just about conceptualizing or creating. It's about envisioning the future of society and walking alongside you to its realization. That's where the unique strength of Pacific Consultants Group lies.
