Disaster Prevention and Flood Damage

Last update date February 8, 2021

In February 2020, a flood hazard map in Seya Ward was updated.
Along with that, Seya Ward has prepared a flood hazard map and information on evacuation during storm and flood damage.
The hazard map on the back of this is only [assumed], and if there is more rainfall than expected, flooding outside the inundation area is assumed.
Daily preparation is important not only for everyone in the inundation area, but also for those outside the inundation area.
Please refer to this "Seya's Disaster Prevention and Flood Damage" and prepare for storm and flood damage.
