Kajima Corp is one of Japan’s largest construction and engineering companies. It builds office towers, factories, hospitals, schools, transportation links, tunnels, dams, and other large structures, and it also handles design, project management, and maintenance for complex building and infrastructure jobs. In simple terms, Kajima is the kind of company clients hire when they need a major project planned, engineered, and built end to end.

Its main customers are governments, local public agencies, developers, manufacturers, utilities, and large companies that need specialized construction work. Kajima makes money mainly by winning contracts and being paid for construction, civil engineering, design, and related services. It also has activities tied to real estate and building management, which help it earn recurring income beyond one-off construction projects.

What makes Kajima different is its role as a high-skill contractor for demanding projects where safety, engineering know-how, and execution matter a lot. It sits close to the center of the construction value chain: it can plan, design, build, and maintain major assets rather than just supply materials or equipment. That gives it a business model based on technical expertise, long client relationships, and the ability to handle large, complicated work that smaller contractors cannot easily take on.
