This photo shows the image in case that the Soka station front is flooded in the depth of 3 m.

If the Tone River should overflow, the water may be 3 m in depth in the worst case, and the water may stay for a week.

  • Houses in Soka City are hardly assumed to suffer from inundation on the second floor or upper, nor to be washed away by landslide disaster or by the river water.
  • Make your own timeline of when and how you act in times of flood, so that you can picture in your mind what actions to take in case of emergency.

Basics: Evacuate to the 2nd Floor or Upper Indoors

Q: Why not an evacuation shelter ?

A: Evacuation means to escape from the danger.
Carry out home evacuation (Vertical evacuation to the second floor or upper) to seek safety indoors.

Many people will be living in an evacuation shelter in a limited accommodation, creating crowdedness.

Home evacuation will enable you to live in a familiar place, protecting privacy.

If you have difficulty moving to the second floor …

In case you live in a one-story house, or feel insecure, and wish to evacuate to the house of relative or of a friend, or to an evacuation shelter, start preparation to evacuate in good time.
