Kajima Corporation

Kajima Corporation

Kajima Corporation traces its lineage to Iwakichi Kajima, a master carpenter who founded the Tokyo-based firm in 1840. Today, listed on the Tokyo Stock Exchange, it stands as one of Japan's four dominant general contractors, but its investment arm operates with a permanent-capital posture akin to a corporate-controlled family office. The Amano family retains influence, though the firm is now broadly held, with Executive Vice President Yoshikazu Oshimi leading overseas development and investment strategy alongside President Amano. Kajima deploys capital across real estate development, infrastructure concessions, and renewable-energy projects. Its portfolio spans office towers in Southeast Asia, highway and rail projects in North America, and a growing pipeline of solar and onshore wind farms in Japan and Taiwan. The company co-developed the Shiodome Sumitomo Building in Tokyo and has taken equity stakes in US water-infrastructure projects. It increasingly structures direct co-investments alongside institutional partners, rather than acting solely as a contractor. October 2023: Kajima announced a material expansion of its data-center development platform in Greater Tokyo and Osaka, reflecting a strategic pivot to digital infrastructure as a long-duration real-asset class. The group maintains regional hubs in Singapore, London, and Los Angeles. Philanthropic activity runs through the Kajima Foundation for the Arts, which supports architectural research and cultural preservation. Kajima's structural distinction lies in its dual role as both construction contractor and equity investor, giving it cost-of-entry and origination advantages that pure financial sponsors lack. This hybrid model allows it to self-generate pipeline, particularly in complex infrastructure where construction risk deters conventional funds.
