SusHi Tech Tokyo 2026 G-NETS Leaders Summit  Communiqué 

I. The role of cities in the current global landscape 
The global landscape is rapidly changing, with widening divisions and growing uncertainty.  Even under such circumstances, with a focus on our people, cities can advance discussions and actions to help one another. Across the globe, increasingly frequent and severe natural disasters are occurring right before our eyes, presenting urgent, shared issues that the world’s cities must confront together in order to safeguard the lives and assets of our residents. 

As such, by realigning the themes of G-NETS into “Urban Resilience to Climate Change and Natural Disasters” and “Well-being in Cities,” we will accelerate multicity lateral cooperation to share our respective knowledge and experience, and generate a tide of international cooperation. Additionally, to strengthen the resilience of participating cities against natural disasters, we will promote practical initiatives through the Resilience Sub-Working Group that was established under the Working Group for working-level officials. We will also leverage the cutting-edge technologies of Tokyo-based startups and engage in demonstration projects to help enhance resilience and solve other challenges faced by the world’s cities. 

At the G-NETS Leaders Summit held in Tokyo in April 2026, we, the leaders of 55 cities, engaged in two days of discussions under the overarching theme of “A new urban future built on climate and disaster resilience.” 　

We, the participating cities, will, based on the shared understanding and the policy directions set forth below, further deepen practical initiatives and the sharing of knowledge through the G-NETS platform in order to enhance resilience. While partnering with startups and other diverse stakeholders, and also striving to improve the financial foundation of our respective cities, we will advance solutions to shared urban challenges with the aim of realizing a sustainable world. 


II. Urban Resilience to Climate Change and Natural Disasters 
The threat of natural disasters is growing across the world, as evidenced by increasingly severe storm damage; earthquakes and tsunamis; and heat waves, droughts, and forest fires. To ensure the safety and security of our cities, and to safeguard the lives and assets of our residents, it is crucial for us to engage in both hard and soft initiatives and steadily promote measures against natural disasters. 
Advancing climate change measures that also consider industrial structural transformations and promoting harmony with the environment are similarly essential for urban sustainability. To accelerate these measures, we will promote the real-world application of cutting-edge technologies through supporting and utilizing startups, with the aim of enhancing urban climate and disaster resilience. 

A. Measures against natural disasters 
1. Storm damage (heavy rain, strong winds, flooding, storm surge, sediment disasters): 
Storms and floods have grown increasingly frequent and severe due to intensifying climate 
change in recent years. To address this challenge, we will engage in river flood prevention 
through the construction of riverbank protection and regulating reservoirs, stormwater runoff 
control through green infrastructure development, and measures to prevent sewer system 
inundation. We will also advance storm surge protection measures through the raising of 
seawalls and river embankments, promote the development of and relocation to high ground, 
and advance measures against sediment-related risks. Through these measures, we will 
enhance preparedness for storm damage.  

2. Earthquakes and tsunamis: Earthquakes and tsunamis can strike cities at any time. To be fully prepared for these risks, we will engage in the seismic retrofitting and fireproofing of 
buildings and urban infrastructure, the removal of utility poles, soil liquefaction countermeasures for buildings, the improvement of roads including emergency transport networks, and the diversification of evacuation shelters. We will also promote the refinement of firefighting and rescue activities, the enhancement of local disaster preparedness, and the construction and improvement of infrastructure such as coastal protection facilities and port and harbor facilities. Through these efforts, we will aim to create resilient cities where people can live safely and with peace of mind.  

3. Heat waves, droughts, forest fires: Climate change has brought about intensifying heat. To address this issue, we will promote heatstroke countermeasures, mitigation of the heat island effect through heat-reflective pavement and other solutions, and the establishment of better urban and housing environments such as by introducing green infrastructure and providing support for insulating homes. Additionally, to address droughts and forest fires, we will ensure energy and water security, refine firefighting and rescue activities, and enhance local disaster preparedness. Through these measures, we will strengthen resilience to heat waves and other related risks.
