The purpose is to protect the lives, health, and properties of Tokyo residents from disasters by implementing preventive measures, emergency and recovery measures, etc. related to earthquakes and other disasters, and the plan is reviewed annually and amended when deemed necessary based on damage estimates, lessons learned from actual large-scale disasters, revisions to related laws and regulations, and trends in the national government. Recently, after reviewing "the Damage Estimates in Tokyo due to an Earthquake Directly Hitting Tokyo" for the fi rst time in 10 years, we revised "the Earthquake Edition" in May 2023 based on the status of disaster preparedness efforts, changes in the social environment since the Great East Japan Earthquake, and other factors. In addition, in May 2025, based on "Guidelines for Responding to Large-Scale Volcanic Eruption Ashfall" regarding the countermeasures against Volcanic Eruption Ashfall of Mt. Fuji, we have placed the countermeasures against ashfall in the plan, and regarding volcanic eruption countermeasures in the island area, revised "the Volcano Edition" from the viewpoint of further strengthening evacuation system toward securing safety for the citizens of the islands. The Tokyo Disaster Prevention Plan is a project plan formulated to promptly and systematically promote disaster prevention measures against natural disasters such as earthquakes, strong winds, fl oods, and volcanic eruptions. This plan is based on the Tokyo Metropolitan Ordinance for Earthquake Disaster Measures and includes specifi c measures to ensure the safety of residents.Section 4 Tokyo Metropolitan Government Crisis Management SystemMain Contents of the Tokyo Metropolitan Area Disaster Prevention Plan (Earthquake Version)1.
