Predicted flooding from a tsunami in Ota
The maximum height of a tsunami in Ota occurring during high tide is predicted to be 1.58 meters T.P.* for an earthquake in northern Tokyo Bay, and 2.27 meters T.P. for a Genroku-type Kanto earthquake.
Ota is equipped with a levee and seawall built taller than the height of the tsunami, so no damage is predicted. However, certain areas of the ward are predicted to experience flooding if the flood gates are open.

Temporary Tsunami Evacuation Facilities
Certain places in Oda have been designated as “temporary tsunami evacuation facilities.” Located mainly on the shore and along the Tamagawa River, they can be used for temporary, emergency evacuations. Please refer to the “Tsunami Hazard Map” for a list of these facilities.
