02. Vision for a more resilient Tokyo in the 2040s
Build a city that “does not collapse, does not burn, and people survive” even in the event of a major earthquake.
-
Earthquake-resistant buildings and communities that do not burn or spread fire protect the lives and livelihoods of Tokyo residents.
-
The transportation network that supports emergency response activities following an earthquake has been secured, enabling rescue and relief agencies to quickly reach their destinations.
03. Addressing each crisis
Emergency routes
Eliminate road blockages for designated disaster response routes.
-
Promote the removal of utility poles
-
Expand earthquake-proof support for buildings along roads
Disaster Management Facilities
Improve disaster response functions.
-
Develop roads that will serve as access routes to wide-area disaster management facilities and grade separation with relevant railway lines
-
Expand functions and promote the development of disaster-prevention docks
Areas with close-set wooden houses
Create communities that do not burn or spread fire.
-
Expand support for efforts, including the reconstruction of areas with close-set wooden houses
-
Establish a system for eliminating utility poles on private roads, etc., and for subsidizing the costs
Earthquake-resistant homes
Reduce the number of deaths due to building collapse, etc., caused by an earthquake by around 80%.
-
Expand support for earthquake-proofing older wooden houses in the new building standards
-
Expand support for earthquake-proofing apartment buildings in the new building standards
Evacuation measures
Eliminate crowding in evacuation centers.
-
Promote housing complexes that are designed to make it easier to continue living at home
-
Promptly disseminate information about crowding conditions at evacuation centers
Tokyo Islands
Keep Tokyo islands from becoming cut off.
-
Complete quays necessary for emergency transportation
-
Assess damage using satellites, etc.
