Safety measures you can take at home

- Large earthquakes can topple furniture and send objects flying everywhere. Please make sure to secure furniture and consider your room's layout.
- Examples of things you can use to help prevent your furniture from toppling over include L-shaped fittings, adhesive mats, and tension rods.
- Avoid placing heavy objects in high locations. Instead, keep them lower down in drawers, etc.

Preparation of emergency provisions and supplies and an emergency kit

- In the wake of a disaster, you will have difficulty purchasing food and other everyday items. Prepare the necessary emergency provisions and supplies according to your family's needs. Also, make sure to prepare an emergency kit that you can pick up and take with you immediately when evacuating.
- Prepare at least three days' worth of provisions and supplies.
- One of the best ways to ensure that you always have a sufficient stock of items is to follow the rolling stock principle - i.e. create an ongoing stock by buying a little more food and other everyday items than you usually need according to who is in your family and your lifestyle, and use up your stock in order while constantly replacing items with new ones.

Emergency provisions and supplies

Drinking water
Amount per person: 9 liters for 3 days. For a family of 3,for example,this would mean 3 people*9 liters=27 liters.
Food
Foods which do not require cooking, such as crackers, canned foods (in cans which do not require a can opener), etc.
If you have any allergies, please keep a stock of items suitable for your needs.
Emergency toilet sets
People are said to urinate on average 5 times a day. This means you will need around 15 emergency toilet sets for 3 days. You can purchase these at a home center, etc.

Emergency kit items

Flashlight or lantern
Make sure to also prepare some spare batteries.
Portable radio
Make sure to prepare a radio which can receive both AM and FM frequencies, as well as a large stock of spare batteries.
Valuables
Cash, bank book, seal, health insurance card
Other items
Paper plates, paper cups, first aid kit (adhesive plasters, etc.), everyday medicine, medicine handbook, cell phone charger, wet wipes, sanitary items, plastic bags, towels, toothbrush and toothpaste, work gloves, cellophane wrap, a whistle

Evacuation sites

Seek shelter in an evacuation site if your home is no longer safe because it is at risk of collapse or a fire.

Temporary evacuation sites

If you need to evacuate, please first go to the local evacuation site designated by your neighborhood association, etc. However, circumstances may mean that you need to go directly to another evacuation site without first going to the local evacuation site.

Evacuation areas

Evacuation areas are places for people to go when fires are spreading.
These sites can be used temporarily to protect yourself from the radiant heat and smoke of spreading fires caused by an earthquake.

Evacuation shelters

Evacuation shelters serve as places for people to go if their homes have be rendered uninhabitable due to earthquake damage.
These shelters open in Yokohama City in the event an earthquake measuring 5 or more on the seismic scale is recorded, even if only in a single location. Anybody can seek refuge in one of these shelters. These shelters are stocked with minimal supplies of food and water that people will need for daily life during their temporary stay. And they are also equipped with equipment needed for rescue work, etc.
Things to be aware of when evacuating
You are not allowed to drive to evacuation shelters in a car. Please walk when evacuating.

Talk about what to do in the event of a disaster with your family

- Decide how to contact each other in the event of a disaster.
- Decide on a place to evacuate or congregate in the event of a disaster.
