Tokyo
Japan
Tokyo is projected to face increased climate risks due to heavy rainfall events, which are expected to become more frequent and intense. These changes will likely result in greater flooding risks, stressing urban infrastructure and leading to potential disruptions of essential services. The city's topography, with its dense urban population and extensive built environment, exacerbates its vulnerability to such climatic shifts. Overwhelmed drainage systems may compound flooding issues, risking public safety and economic activity. The future of Tokyo will depend on how effectively it can mitigate these risks and adapt to a changing climate, especially concerning heavy precipitation.
Hazard Outlook
How will Tokyo's projected climate hazards compare to other cities under a 3.0°C future warming scenario?
Maximum Rainfall
Tokyo's projected maximum rainfall of 18 mm is among the highest of all cities globally.
Longest Heatwave
Tokyo may experience heatwaves lasting up to 6 days, higher than most other cities.
Elevation
At 41 m elevation, Tokyo faces elevated risk from coastal flooding and sea level rise.
Maximum Temperature
Tokyo's projected maximum temperature of 9.1°C is near the median of cities globally under a 3.0°C warming scenario.
Heavy Rainfall Days
With 10 days of heavy rainfall expected, Tokyo ranks near the median of cities for extreme precipitation events.
