Tokyo Metropolitan Government

The Governor of Tokyo, Yuriko Koike, sets the strategic investment direction through her policy planning staff, who coordinate the 'Invest Tokyo' fund and related startup-attraction programs. Day-to-day treasury operations and municipal bond issuance are managed by the Bureau of Finance. The Governor's direct involvement in economic policy — including her 'SusHi Tech Tokyo' branding — signals that investment decisions are ultimately political and tied to her urban-development agenda.

TMG is formally a municipal government treasury, but under Governor Koike it has taken on characteristics of a strategic investment fund. The ¥100 billion 'Invest Tokyo' vehicle makes direct co-investments in later-stage startups to incentivize relocation, which is closer to a sovereign-development fund's mandate than to passive cash management. The city also holds substantial operating real estate, cultural assets, and infrastructure that give it a diversified asset-owner profile distinct from most municipal balance sheets.

'Invest Tokyo' is a ¥100 billion co-investment vehicle that takes direct equity stakes in later-stage technology startups alongside institutional venture firms. The fund targets companies in sectors aligned with Tokyo's smart-city and sustainability goals: energy transition, urban mobility, advanced manufacturing, and digital infrastructure. The ultimate objective is not purely financial return but to persuade portfolio companies to establish Asian headquarters within Tokyo's Special Zone for Asian Headquarters, where they receive tax incentives and regulatory support.

TMG is a regular issuer of municipal bonds used to fund long-dated infrastructure and sustainability-linked capital projects. This debt program gives the government a direct presence in Japanese credit markets and a cost of capital that influences how it evaluates direct investments in urban infrastructure. Proceeds fund everything from public transit upgrades to green-energy installations, effectively making the city's liability-management function a parallel arm of its investment strategy.

Tokyo Metropolitan Government collaborates with Japan's Government Pension Investment Fund (GPIF), the world's largest pension fund, on ESG and impact-investing standards in Japan. This relationship is not a co-investment partnership but a policy-alignment effort, with both entities working to raise governance and sustainability benchmarks across Japanese capital markets. TMG also engages with global institutional investors through its participation in C40 Cities and ICLEI, using these networks to source co-investors for urban-climate projects.

TMG does not publish a formal exclusion list, but its direct co-investments through 'Invest Tokyo' are explicitly tied to the 'SusHi Tech Tokyo' vision, which channels capital toward sustainability, technology, and urban-infrastructure themes. Sectors with no clear policy linkage to Tokyo's economic-development or climate goals — such as extractive industries, defense manufacturing, or consumer discretionary — are absent from its disclosed investment activity. The government's public-sector mandate also imposes an implicit avoidance of anything brand-damaging to an elected administration.

They are not fully separated — and that is the structural differentiator. The same government that co-invests in startups through 'Invest Tokyo' also controls the zoning, permitting, and tax-incentive levers that make Tokyo hospitable to those companies. This integration creates a policy-capital hybrid that is intentionally designed to eliminate the gap between investment and regulation. Internal firewalls exist between bureaus, but the Governor's office coordinates both functions, meaning a startup that accepts TMG capital is simultaneously a portfolio company and a regulatory stakeholder.
