Eight Ways to Stay Safe from a Storm Surge

  • Immediately Start Your Evacuation When a Typhoon Warning Has Been Issued!
    (Don't Wait for an Announcement of a Storm Surge Warning to be Issued)

    • When a typhoon approaches Tokyo, strong winds will begin to blow before the sea level rises, making it difficult to move to a safe place. When a windstorm warning is issued by the Japan Meteorological Agency, start your evacuation to a safe place.
      Windstorm warnings are generally issued three to six hours before the windstorm begins.
  • Start Your Evacuation When the Area Where You Live is Lower Than the Second Floor in the Area Where Storm Surge Flooding is Assumed

    • If you live on or below the second floor, start evacuating as soon as a typhoon warning has been issued.
  • Immediately Go to the Storm Surge Evacuation Shelter When You are Recommended to Evacuate and Evacuation Instructions Have Been Issued by Your Municipality!

    • If an evacuation advisory or evacuation order has been issued, immediately proceed to a nearby storm surge evacuation shelter. Evacuate to a strong building that has three or more floors if you do not know where to evacuate.
  • Storm Surge Flooding Hazard Information is Your Last Chance to Protect Your Life!

    • When the storm surge flooding hazard information is issued, there is imminent danger of storm surge flooding! Evacuate immediately to an evacuation shelter, or a strong building that has three or more floors, rather than attempting to travel far.
  • When it is Impossible to Escape, "Act to Stay Safe!”

    • If water reaches the outside of your home and you can't get out because of the storm, get away from windows in a room on the second floor or higher in your home.
  • Precautions When Evacuating

    • Evacuate before the weather gets bad, evacuate to outside the expected area of flooding, and evacuate while public transport is still running (do not attempt to evacuate in your car)!
  • After the Water Subsides

    • Never return to your home or approach the sea, river, or other waterway until your evacuation advisory or evacuation order has been lifted, even if the water has retreated. (This is because tide levels may continue to fluctuate even after the weather has calmed down.)
  • How to Collect Information Necessary for Flooding Damage

    • If the danger of flooding is imminent, such as a storm surge or the like, get information issued by the Japanese government, the Tokyo Metropolitan Government, or your municipality using a radio or your smartphone.
