The Tokyo Metropolitan Government (TMG) has unveiled plans to launch the world’s first certified climate resilience bond, a landmark move in sustainable finance that will channel proceeds directly into projects strengthening the city’s defenses against natural disasters and the accelerating impacts of climate change.

Pioneering a New Frontier in Resilience Finance

Under the new program, TMG plans to raise approximately ¥50 billion ($330 million) through the issuance of TOKYO Resilience Bonds, with proceeds earmarked for initiatives under the TOKYO Resilience Project, the city’s flagship adaptation and disaster preparedness framework launched in 2022. The offering marks a historic first a bond certified under the Climate Bonds Initiative’s (CBI) newly launched Resilience Criteria and Taxonomy, expanding global green finance beyond mitigation projects to include adaptation and resilience-focused investments.

“In Japan and around the world, it has become an urgent priority to address increasingly severe storms and floods caused by global warming,” said Yamashita Satoshi, Director General of the Bureau of Finance, Tokyo Metropolitan Government. “Against this backdrop, the Tokyo Metropolitan Government has decided to issue the TOKYO Resilience Bond, establishing a new model of financing that supports investments in climate change adaptation measures.”

Funding Infrastructure to Protect Tokyo from Climate Extremes

Proceeds from the TOKYO Resilience Bonds will exclusively finance infrastructure upgrades and urban adaptation projects designed to mitigate risks from flooding, earthquakes, volcanic ash, power disruptions, and other extreme events.

Eligible projects under the TOKYO Resilience Bonds Framework include:

Upgrading small and medium-sized rivers to improve flood resilience and drainage capacity.
Developing coastal protection infrastructure, including seawalls and storm surge barriers.
Reinforcing river embankments and floodways to manage increased rainfall intensity.
Undergrounding utility poles and power lines to reduce collapse risks during typhoons and earthquakes.
Renovating ports and coastal facilities to safeguard remote islands vulnerable to rising sea levels and storm impacts.
Developing sediment and erosion control systems to stabilize slopes and prevent landslides.

These initiatives fall under the broader TOKYO Resilience Project, a multiyear plan designed to fortify one of the world’s most densely populated urban regions against compound climate risks.

A New Model for Urban Climate Adaptation

The Climate Bonds Initiative (CBI), which certified the bond, hailed Tokyo’s effort as a “landmark moment” for global sustainable finance.

“By directing capital into projects that safeguard millions of citizens from floods, storm surges and typhoons, the Tokyo Metropolitan Government is setting a precedent for cities everywhere to invest in resilience,” said Sean Kidney, CEO of CBI. “This first certification under the Resilience Taxonomy creates a new generation of resilience and adaptation-focused finance.”

The Resilience Taxonomy, released earlier this year, expands the definition of green and climate bonds to include investments that protect communities, ecosystems, and infrastructure from physical climate risks, a category previously underrepresented in sustainable debt markets.

Positioning Tokyo as a Global Leader in Climate-Adapted Finance

For Tokyo, this bond issue represents more than a financial milestone, it’s part of a strategic shift toward embedding resilience planning into fiscal and investment policy. The TMG has already prioritized sustainability-linked bonds and green municipal instruments, but this new issuance signals a transition toward climate adaptation as a central pillar of the city’s financial strategy. With extreme weather events costing Japan billions annually and climate projections showing higher risks of typhoons, heatwaves, and coastal flooding, the initiative will help mobilize private capital toward long-term resilience infrastructure. The issuance also aligns with Japan’s National Climate Adaptation Plan and supports Tokyo’s ambition to achieve carbon neutrality by 2050, demonstrating that mitigation and adaptation can progress hand in hand.

Setting a Global Precedent for City-Level Climate Finance

As the first certified climate resilience bond in the world, Tokyo’s initiative is expected to become a template for other major cities, from New York to Singapore, seeking to finance adaptation measures through capital markets. By coupling strong governance with transparent reporting on the use and impact of proceeds, TMG’s framework provides investors with a clear pathway to fund infrastructure that directly enhances urban safety and climate preparedness. In a century defined by intensifying natural hazards, the TOKYO Resilience Bond represents a powerful new tool: mobilizing finance not just to prevent emissions, but to protect lives, livelihoods, and cities from the climate shocks already unfolding.
