Obayashi

Obayashi Corporation is a publicly traded Japanese construction firm (TYO: 1802) dating to 1892. Takeo Obayashi serves as its Chairman, and the family office deploys his capital alongside interests aligned with the corporation. The office is not a subsidiary but shares the chairman's strategic horizon. Its real estate portfolio includes properties developed or sourced through the corporation's global network, as seen in its London and Bangkok holdings.

Art patronage is a parallel asset strand, not a philanthropic afterthought. Takeo Obayashi commissioned Tadao Ando to build the Yu-un Guesthouse in Tokyo to house his collection, and the office holds site-specific commissions. His positions on the boards of MoMA, Tate, and the Centre Pompidou underscore how cultural capital facilitates access and co-investment dialogue that pure financial engineering cannot replicate.

Real estate forms the core, spanning office towers in London and Tokyo, mixed-use, industrial logistics, and residential. However, the office also maintains a global renewable energy portfolio, indicating an appetite for infrastructure-adjacent energy assets. No venture capital or public-equities allocation is apparent from public disclosures.

Takeo Obayashi appears as the sole named principal and decision-maker. The office does not publicize a CIO or investment committee. Given the long-term, buy-and-hold nature of its property assets in London, Bangkok, and Tokyo, decisions likely flow through a tight, family-centric structure closely integrated with the chairman's office at Obayashi Corporation.

The Obayashi Foundation operates as a distinct philanthropic entity. While established by the same family, its grant-making activities are structurally separate from the direct investment portfolio. No portfolio assets are held inside the foundation, consistent with standard Japanese corporate-philanthropy separation practices.

No evidence of regular co-investment alongside external GPs or limited partners exists in the public record. The office's known London, Bangkok, and Tokyo assets are held directly or through wholly-owned structures. An exception is the strategic partnership with SRI International for open innovation in Silicon Valley, though this appears exploration-oriented rather than a co-investment fund structure.

The disclosed portfolio spans three continents: City of London (60 Gracechurch Street commercial freehold, 20 Gracechurch Street mixed-use), central Tokyo (Shinagawa Intercity Tower B, Yu-un Guesthouse), and Southeast Asia (O-NES TOWER, Bangkok). Japanese logistics is represented by the Kumiyama Distribution Center in Kyoto.
