Your Phone Will Scream in Japanese During a Disaster — Here's How Foreigners Stay Safe in Japan (2026)
Your Phone Will Scream in Japanese During a Disaster — Here's How Foreigners Stay Safe in Japan (2026)
Updated September 2026 | Written by Luna H
It happens without warning. A piercing alarm blasts from every smartphone in the room. Your screen lights up with kanji you can't read. People around you drop to the floor and cover their heads. You freeze — because nobody told you what to do.
Japan averages 1,500 detectable earthquakes per year. Most are small. But living here without a disaster plan isn't just uncomfortable — it's genuinely dangerous. And for foreigners, the biggest risk isn't the earthquake itself. It's not knowing what the alerts mean, where to go, or what to have ready.
This guide gives you everything you need to prepare before disaster strikes — apps, emergency kit, evacuation procedures, and the Japanese phrases that matter when it counts.
💡 Quick Summary — Do These 3 Things First
- Download Safety tips app — Japan's official multilingual disaster alert app (15 languages including English). Free.
- Build a 3-day emergency kit — Water, food, cash, documents, medications. Store it by your front door.
- Find your evacuation shelter (避難所) — Check your ward office or local hazard map before you need it.
Understanding Japan's Alarm System — What Each Sound Means
Japan has two separate alert systems that foreigners often confuse:
1. Earthquake Early Warning (緊急地震速報 — Kinkyū Jishin Sokuho)
A distinctive ascending beeping tone broadcast via every mobile phone, TV, and radio in the affected area. This warns you seconds before shaking arrives. When you hear it:
- Indoors: Drop, cover your head, hold on under a sturdy table or desk
- In a kitchen: Turn off the gas immediately, then take cover
- Outdoors: Move away from buildings, walls, and utility poles. Crouch low and protect your head
- In a car: Slow down gradually, pull to the left side of the road, do not stop on a bridge
⚠️ Critical: Don't Rush to Exit During Shaking
The most dangerous moment is during active shaking — not after. Most injuries happen from falling objects and broken glass. Stay covered until shaking completely stops. Only then check for fire, gas leaks, and exit routes.
2. J-Alert (全国瞬時警報システム)
Japan's national warning system for larger threats: major earthquakes, tsunamis, missile threats, and extreme weather. Broadcasts via outdoor speakers, TV, and mobile phones. The message is mostly in Japanese — which is exactly why you need the apps below.
Japan's Disaster Warning Levels — The 5-Level Evacuation Scale
Japan uses a 5-level evacuation warning scale. As of 2026, the "evacuate by Level 4" principle is the standard you must know:
| Level | Japanese | What It Means | Action Required |
|---|---|---|---|
| Level 1 | 災害への心構えを高める | Weather warning issued | Stay alert. Check news. |
| Level 2 | 避難行動の確認 | Danger is rising | Confirm evacuation route. Prepare kit. |
| Level 3 | 高齢者等避難 | Elderly/disabled: evacuate now | If you need extra time to evacuate, leave now. |
| Level 4 ⚠️ | 避難指示 | Evacuation order | EVACUATE NOW. All residents must leave. |
| Level 5 🔴 | 緊急安全確保 | Disaster already happening | Safe evacuation may no longer be possible. Protect yourself where you are. |
The rule: evacuate at Level 4. Don't wait for Level 5. By Level 5, it may be too late to safely move.

Two Types of Evacuation Locations — Most Foreigners Don't Know the Difference
This is one of the most critical things foreigners don't know — and confusing the two can put you in danger:
- 指定緊急避難場所 (Shitei Kinkyū Hinan Basho) — Emergency Evacuation Site: Where you go immediately during a disaster. Usually open spaces like parks, schoolyards, or high ground. You go here to be safe from the immediate threat (tsunami, fire, flood). You do NOT stay here long-term.
- 避難所 (Hinanjo) — Evacuation Shelter: Where you go after the immediate danger has passed. Usually schools or community centers. You can stay here for days or weeks if your home is uninhabitable.
Hinan-basho (避難場所) = immediate safety. Hinanjo (避難所) = where you stay after. Learn both words.
To find your designated shelter: visit your local ward office (区役所/市役所) and ask for your area's ハザードマップ (Hazard Map). Most ward offices have English-language versions. You can also search online: [your city name] ハザードマップ.
Your 3-Day Emergency Kit — What to Prepare
Japan's Cabinet Office recommends all households keep at least 3 days of emergency supplies. For foreigners, there are additional items beyond the standard list:
| Category | What to Include | Notes for Foreigners |
|---|---|---|
| Water | 2 litres per person per day × 3 days | Store in sealed bottles. Tap water may be unsafe after major earthquakes. |
| Food | 3-day supply of non-perishable food | Japanese retort-pack food (レトルト) is ideal — heated in hot water, long shelf life. Try it before a disaster so you know what you can eat. |
| Documents | Copies of Residence Card, passport, insurance card, bank account info | Critical for foreigners. Store copies in a waterproof bag. A lost Residence Card during a disaster creates major legal complications. |
| Cash | ¥10,000–¥30,000 in small bills | ATMs and card terminals go offline in major disasters. Cash is essential. Small coins for vending machines (often still operational after earthquakes). |
| Medications | 3–7 day supply of all regular medications | Include medication name in English AND Japanese (on the package). Some medications unavailable in Japan without re-prescription. |
| Phone charger | Portable battery bank (fully charged) | Power outages can last days. A charged battery bank keeps your disaster apps and emergency contacts accessible. |
| Flashlight + radio | LED flashlight + hand-crank or battery radio | NHK Radio (AM 594 kHz in Tokyo) broadcasts emergency information in English during major disasters. |
| Foreigner extra: translation | Printed Japanese phrase sheet for emergencies | Phone batteries die. Have key phrases on paper. See the phrase section below. |
Where to buy: Most major 100-yen stores (Daiso) and home centers (Cainz, Kohnan, Joyful Honda) sell pre-packaged emergency kits (防災セット). Convenience stores also stock water, food, and basic supplies — buy in stages, not all at once.
Registering With Your Ward Office — What Foreigners Must Do
Two registrations that many foreigners skip — and shouldn't:
1. Disaster Information Registration
Most ward offices allow foreign residents to register for multilingual emergency text alerts. Visit your local ward office (区役所/市役所) and ask about 外国人向け災害情報 (gaikokujin muke saigai jōhō — disaster information for foreigners). Some cities send SMS alerts in English, Chinese, Korean, Portuguese, and other languages.
2. Register as a Person Requiring Support (要支援者登録)
If you have a disability, medical condition, or are elderly, register with your ward office as a person requiring disaster support (避難行動要支援者). This ensures local volunteers know to check on you during an evacuation.
After the Shaking Stops — What to Do
- Check for injuries — yourself first, then others nearby. Call 119 for ambulance/fire emergencies only. Lines are overwhelmed after major earthquakes.
- Check for gas leaks — if you smell gas, open windows immediately, do NOT switch any lights or appliances on or off, leave the building, and call your gas company from outside.
- Turn off electricity at the breaker — electrical fires from damaged wiring are a leading cause of post-earthquake deaths in Japan. Turn off the main breaker before leaving.
- Do not use elevators — even if they appear to be working. Use stairs only after earthquakes.
- Be prepared for aftershocks — Japan commonly experiences aftershocks for days after major earthquakes. Stay alert.
- Contact your embassy — register with your home country's embassy for emergency assistance. Most embassies in Japan have 24-hour emergency lines.
💡 The Disaster Message Dial — 171
After a major disaster, regular phone calls may not connect due to network overload. Japan operates a Disaster Emergency Message Dial: 171. Dial 171, follow the prompts to record or play back a voice message linked to a phone number. Use this to let family know you're safe, or to hear messages from loved ones when regular calls won't go through.

Common Mistakes Foreigners Make
- Ignoring small tremors. Frequent small earthquakes make foreigners complacent. Every tremor is a reminder to check your kit and review your plan — not ignore it.
- Not knowing their evacuation shelter in advance. During a disaster is the worst time to search for this. Find it now at your ward office or on the local hazard map.
- Relying only on phone apps for alerts. Battery dies, networks overload. Keep a printed emergency phrase sheet and have cash ready for when digital systems fail.
- Not having copies of documents. Your Residence Card, passport, and health insurance card are essential for getting help at shelters and hospitals. Keep waterproof copies in your emergency kit.
- Forgetting dietary needs. Japanese shelter food is mostly rice-based. If you have dietary restrictions or allergies, include your own food supply in your emergency kit.
Japan's disaster infrastructure is world-class — but it's built around Japanese speakers who have practiced earthquake drills since kindergarten. As a foreigner, a little upfront preparation closes that gap completely. Download the Safety tips app today, build your kit this week, and find your local shelter on the hazard map. You'll never need most of this — but if you do, you'll be ready.
