　In addition, in recent years, heavy rain and strong winds caused by typhoons and other storms have occurred throughout Japan. To minimize any potential damage, be prepared for heavy rain and strong winds on a day-to-day basis.

Nearby schools will be set up as evacuation centers and temporary shelters to be utilized by people whose homes have been damaged in an earthquake or fire. Post-earthquake evacuation sites (Local Disaster Preparedness Centers) stockpile food, beverages, daily necessities, and disaster prevention materials. Emergency supplies will also be sent to these sites in the event of an earthquake.
* Different evacuation sites are opened in the event of heavy winds or flooding.

To protect yourself in the event of a major fire, evacuate to a safety Evacuation Area.
●Evacuation Area Name
・Honmoku-Sancho Koen region
・Negishi Forest Park and Negishi U.S. Naval Housing district

Key points to evacuating during a tsunami event
◎Evacuate to higher ground faster
When evacuating, get to a place:
・At least five meters above sea level
・On the third floor or higher of ferroconcrete buildings that can withstand shaking during an earthquake.

◎Do not drive your car to evacuate
Do not evacuate with your car (except in cases where you are assisting some with difficulty walking or other extraordinary circumstances). Large numbers of people evacuating by car can cause tariff jams and impede the evacuation process.

Even when no evacuation information has been issued, you can take other actions if you feel danger.

●Warning Level

●Evacuation sites
At Warning Level 3, evacuation sites will be opened for people located near cliffs/slopes, etc.
