Kajima Corporation Kajima Corporation is a major Japanese construction and engineering corporation with a long history in civil engineering, architecture, and real estate development. The company operates across Asia, Oceania, Europe, and the Americas, delivering large-scale infrastructure, high-rise buildings, tunneling, and environmental works. Kajima maintains research institutes, partners with universities and international firms, and participates in landmark projects that intersect with urban planning, transportation, and seismic design.

History

Kajima traces origins to a family-operated firm established in the Edo period by Hachigorō Tōgō and evolved through the Meiji Restoration into a modern construction company alongside peers such as Taisei Corporation, Shimizu Corporation, and Obayashi Corporation. During the Taishō and Shōwa eras the company expanded into railway works for Japanese National Railways, port construction for the Port of Yokohama, and urban rebuilding after the Great Kantō earthquake. Kajima played roles in wartime mobilization with projects linked to the Imperial Japanese Army logistics network and later reconstructed facilities during the Allied occupation under guidance from entities including the Supreme Commander for the Allied Powers. Postwar boom projects connected Kajima to the development of the Tōkaidō Shinkansen, expressway programs like the Meishin Expressway, and urban mass transit systems such as the Tokyo Metro. In the late 20th century the company internationalized with ventures in Southeast Asia, collaborating on megaprojects with firms such as Hyundai Engineering & Construction and Bechtel. Kajima has weathered economic cycles including the Japanese asset price bubble and global financial crises, adapting through diversification into real estate investment trusts and public–private partnership models exemplified by projects with Japan Railway Construction, Transport and Technology Agency.

Business Operations

Kajima organizes operations into construction, civil engineering, urban development, and overseas business divisions similar to multinational peers Vinci, Skanska, and Hochtief. The firm provides turnkey services for skyscrapers, airports, and stadiums working with architects like Kenzō Tange and firms including Nikken Sekkei and SOM (Skidmore, Owings & Merrill). Kajima’s civil engineering teams undertake tunneling using methods developed alongside manufacturers such as Hitachi and Komatsu, and collaborate on building information modeling projects integrating software from Autodesk and Bentley Systems. Kajima participates in public–private partnership procurement with agencies like the Ministry of Land, Infrastructure, Transport and Tourism and joint ventures with contractors such as Taisei Corporation and Obayashi Corporation. Financial operations include construction finance, real estate asset management with connections to Japan Real Estate Investment Corporation, and infrastructure investment funds co-sponsored by global investors like Goldman Sachs and Mitsubishi UFJ Financial Group.

Major Projects and Construction Works

Kajima has been the lead contractor or partner on numerous prominent works: high-rise developments in Shinjuku and Roppongi Hills districts; airport terminals at Narita International Airport and modernization works at Haneda Airport; tunneling for projects including the Seikan Tunnel studies and urban subway extensions for Osaka Metro and Sapporo Municipal Subway. The company built stadiums and arenas used in events such as the FIFA World Cup and Summer Olympics competitions hosted in Tokyo, and delivered cultural facilities for institutions like the National Museum of Emerging Science and Innovation and the Tokyo National Museum. Kajima completed complex marine reclamation and port infrastructure at sites including Kobe Port and the Port of Singapore through partnerships with local authorities and global contractors. In energy and industrial sectors, Kajima worked on power plant civil works for utilities including Tokyo Electric Power Company and petrochemical facilities for corporations like Mitsubishi Heavy Industries.

Research, Technology, and Innovation

Kajima operates dedicated research centers that collaborate with academics from institutions like The University of Tokyo, Tokyo Institute of Technology, and Keio University on seismic isolation, structural health monitoring, and materials science. The firm advanced base isolation systems and vibration control technologies applied to buildings near seismic fault lines such as the Nankai Trough region, and pioneered modular construction and prefabrication methods in partnership with manufacturers like Mitsubishi Heavy Industries and software developers including Siemens. Kajima has trialed digital twins and IoT-enabled construction sites using sensors from firms like NEC and Panasonic, and contributed to standardization efforts with bodies such as the Japan Society of Civil Engineers and international organizations like ISO.

The company pursues carbon reduction initiatives tied to targets endorsed by frameworks like the Science Based Targets initiative and works on ecological mitigation in projects affecting habitats designated under the Ramsar Convention and local conservation agencies. Social responsibility programs include vocational training with technical colleges such as Kogakuin University, disaster resilience support coordinated with the Japan Disaster Relief (JDR) mechanisms, and community engagement in urban regeneration schemes alongside municipal governments like the Tokyo Metropolitan Government.
