An "evacuation shelter" is a place to go when it is dangerous to stay at home due to an earthquake or storm or flood disaster.
You can also get food and information by going to a "shelter."
On the Yokohama City Disaster Prevention Information Portal, you can check information on the opening of evacuation shelters in the event of a disaster.
