Emergency preparation in Japan is not only about earthquakes. It is about knowing which number to call, how to say your location, where official alerts come from, how your municipality communicates evacuation information, and how your household or workplace will confirm safety.
This guide is preparation support, not a replacement for official warnings, medical advice, fire department instructions, or municipal evacuation announcements. Use it together with the Japan emergency and disaster checklist.
Know which number to call
Japan uses different emergency numbers depending on the situation.
119: fire, ambulance, sudden illness, serious injury, and rescue handled through fire/emergency services.110: police, crime, incidents, accidents, and traffic accidents.
If there is life-threatening danger, a fire, serious illness, or a serious injury, do not wait for a friend to answer messages. Call emergency services first and follow the instructions you receive.
Prepare a short Japanese note you can read aloud:
- Kyukyu desu. Jusho wa … desu.
- Kaji desu.
- Keganin ga imasu.
- Nihongo ga sukoshi shika hanasemasen.
- Chikaku no eki wa … desu.
The Fire and Disaster Management Agency’s ambulance service guide is a useful official starting point for confirming how 119 works.
Use official and local alert sources
Earthquakes, typhoons, heavy rain, flooding, landslides, and evacuation notices are local. A weather app may tell you that something is happening, but your municipality tells you what applies to your address.
Confirm:
- Japan Meteorological Agency warnings and emergency warnings.
- Your city, ward, town, or village disaster-prevention page.
- Shelter maps, wide-area evacuation sites, and local hazard maps.
- Whether your phone receives emergency alerts and evacuation notices.
- School, employer, building management, or dormitory communication channels.
Bookmark the Japan Meteorological Agency’s Emergency Warnings page, but check your municipality for the current local action guidance.
Add disaster preparation to your first week
If you have just arrived in Japan, disaster preparation belongs in your first-week setup. It should sit next to mobile service, address registration, commuting, and daily shopping. Start with First Week in Japan: What to Set Up First, then add the safety layer.
Do three things during the first week:
- Photograph building notices for garbage, management, emergency contacts, and disaster information.
- Check the nearest shelter, wide-area evacuation site, main road, station, and walking route home.
- Put passport copies, residence card copies, insurance card, medicine, cash, and a power bank where you can grab them quickly.
If you still need to handle address procedures, read the ward office moving-in guide. Municipal offices are often the starting point for local rules, disaster maps, and daily-life guidance.
Make a practical go-bag
A go-bag should serve your real life. It should reflect your language level, health needs, commute, household, and building.
Prepare at least:
- Drinking water and shelf-stable food.
- Power bank, flashlight, and batteries.
- Regular medicine, masks, wet wipes, and basic first-aid items.
- Cash, copies of identity documents, and emergency contacts.
- A Japanese note with your address, symptoms, allergies, and usable languages.
If you live in a high-rise, old apartment, riverside area, low-lying area, or slope area, confirm risks for power outage, water outage, flooding, and landslides. When comparing neighborhoods, include safety, routes home, and local hazard information alongside rent and commute in the area guides.
Next step
Open the Japan emergency and disaster checklist and put emergency numbers, your address, shelter information, official sources, and emergency contacts into one note. In a stressful moment, you want a simple procedure you can follow, not ten tabs you found in a rush.
