This hazard map is based on the "Maps for Assumed Flooded Areas from River Waters" and "Maps for Predicted Flooded Areas" in the event of the
expected maximum rainfall, prepared by Aichi Prefecture. The Maps for Predicted Flooded Areas show a wider area of flooding than the area shown by
the Maps for Assumed Flooded Areas from River Waters, as they are prepared in consideration of overflows outside the designated sections of the Maps
for Assumed Flooded Areas from River Waters under the Flood Control Act and floodwater from branch rivers.

If the floodwaters become nearly knee-deep during evacuation!
Evacuate to a
nearby tallbuilding orother shelter!
Normally, evacuation actions in areas where flooding exceeds 50 cm are dangerous. When the waterflow is strong, evacuation actions even in areas where flooding is 15 cm deep can be dangerous.

It is dangerous below the surface ofwater as there are ditches andobstacles there.

Walking barefoot or in boots is dangerous.

Wear work gloves (or ordinary gloves).

In the event of an increased likelihood of a storm, flood or other disaster, take action to protect your life (= evacuation action).
Evacuation action includes the following four actions. Identify dangerous areas for each type of disaster and determine inadvance what action to take.

(1) Movement to an evacuation site or shelter(2) Movement to a safe place other than an evacuation site or
shelter (e.g., a relative's or friend's house)(3) Movement to a taller or stronger building, etc. in theneighborhood

Use a long stick as a cane and walk
while checking for safety.

Wear athletic shoes that can be
securely fastened with laces.

If only flooding from river waters occurs in the event of a heavy
rainfall that occurs about once every 1,000 years (total rainfall of
760 mm in 24 hours)(Assumed flooded areas from river waters published by Aichi
Prefecture based on the Flood Control Act)If flooding from river waters and inland waters occur
simultaneously in the event of a heavy rainfall that occurs about
once every 100 years (total rainfall of 411 mm in 24 hours)

This hazard map shows the most dangerous flooding conditions (extent and depth of flooding) that could occur if the Sakai River,which is managed by Aichi Prefecture, swells, overflows, or bursts its banks in the event of the heaviest rainfall foreseeable(occurring about once every 1000 years).

This hazard map shows the flooding conditions (extent and depth of flooding) if flooding from waters from Class B rivers, lawapplicable rivers and ordinary rivers, and flooding from inland waters, which is caused by the inability of waterways and sewers todrain water, occur simultaneously in the event of a presumed heavy rainfall (occurring about once every 100 years).

This hazard map is based on the "Maps for Assumed Flooded Areas from River Waters" and "Maps for Predicted Flooded Areas" in the event of the
expected maximum rainfall, prepared by Aichi Prefecture. The Maps for Predicted Flooded Areas show a wider area of flooding than the area shown by
the Maps for Assumed Flooded Areas from River Waters, as they are prepared in consideration of overflows outside the designated sections of the Maps
for Assumed Flooded Areas from River Waters under the Flood Control Act and floodwater from branch rivers.

This hazard map is based on the "Maps for Assumed Flooded Areas from River Waters" and "Maps for Predicted Flooded Areas" in the event of maximum
expected rainfall, prepared by Aichi Prefecture, and the maps for the assumed flooded areas from waters from law applicable rivers and ordinary rivers
and the assumed flooded areas from inland waters in the event of maximum expected rainfall, prepared by Toyoake City.
