Be careful during typhoon season!

When heavy rain falls in the river region, or when snowfall in the mountains melts in the spring, a large amount of water flows into rivers, causing flooding. This may cause damage to the coastal protection barriers and the water that overflows the embankments may cause damage to the areas near the river’s shore.

Evacuation procedures

Parent and child evacuating
When evacuating during floods, keep close watch of what is on the ground, help children and the elderly and keep close watch of them so that everyone can evacuate safely.
Things to remember
  • Do not walk bare foot or in boots. It is better to wearing sneakers with shoelaces.
  • To avoid becoming separated from the rest of your family, bind one another together
                with a rope when evacuating.
  • The depth of water you walk in should be about 70cm for men and 60cm for women.
                If the water is at waist-level, do not try to evacuate, but await rescue at a high location.
  • When walking in water, use a long stick for stability and also to search under the water.
  • Lead elderly and sick people by the hand or carry them on your back.
  • Give flotation devices to infants and the elderly.
