The Tokyo Metropolitan Government (TMG) participated in the Smart City Expo World Congress 2025 (SCEWC) held in Barcelona, Spain, from November 4 to 6. Centered on the theme of “Resilience,” the TMG showcased Tokyo’s expertise in disaster response using digital technologies, presenting solutions tailored to different types of disasters and highlighting Tokyo’s comprehensive urban resilience capabilities.

SCEWC is the world’s biggest and most influential event for cities and urban innovation. Hosted annually in Barcelona, it brings together a powerful ecosystem of leaders from global companies, governments, and strategic organizations driving meaningful change. This year marks the fourth time the TMG has exhibited at the event.

Highlights of Tokyo's Exhibit

The Tokyo Pavilion showcased the following initiatives at SCEWC2025:


 

Disaster Prevention and Mitigation Initiatives

As part of our disaster prevention efforts, we introduced initiatives that leverage AI, such as AI-based water level forecasting to support the operation of floodgates and other facilities. Tokyo is a city where urban functions are highly concentrated, and many people live in areas facing the sea. By utilizing advanced technologies like AI, Tokyo works to prevent flooding caused by storm surges　and heavy rain. For more details on this initiative, please refer to the link below.

In addition, Tokyo aims to become a city capable of keeping disaster risks within manageable limits and is promoting mitigation measures to minimize damage. We showcased initiatives such as evacuation guidance supported by robots and efforts to simulate human flow during disasters using digital twin technology.

Addressing Climate Change and Heat Stroke Risks

＊   As of December 2025, the “TOKYO WBGT Map” is suspended as it is outside the heatstroke alert period. This service will resume during the summer heatstroke alert season.

Another highlight was the “Tokyo WBGT Map,” which was released in June 2025. Extreme heat poses a serious threat to vulnerable groups, including the elderly and children. It is essential to encourage preventive actions against heatstroke by providing timely and accurate information.  This map provides information useful for preventing heatstroke by visualizing the Wet Bulb-Globe Temperature (WBGT). Residents can assess real-time information about heatstroke risks in familiar places such as their homes, workplace, and schools, and enabling them to make appropriate decisions regarding their activities.

TOKYO Resilience Project

The “TOKYO Resilience Project” is an initiative aiming to strengthen preparedness for natural disasters—such as floods, storms, and earthquakes—that are increasing in intensity as a consequence of climate change. Its goal is to create a more resilient and sustainable Tokyo, where people can live with peace of mind for the next 100 years. While focusing mainly on hard infrastructure measures, such as infrastructure development, from the standpoint of maximizing the effectiveness of hard infrastructure preparations, the project also combines soft infrastructure measures such as utilizing digital technologies. Through this integrated approach, Tokyo is developing highly effective initiatives.
