Japan is one of the most seismically active countries on Earth — the Japanese archipelago sits at the intersection of four tectonic plates, and the country experiences roughly 1,500 earthquakes every year. For foreigners living in or visiting Japan, understanding what to do before, during, and after an earthquake is not optional: it’s essential. This comprehensive guide covers everything you need to know in 2026.

Understanding Japan’s Earthquake Risk

Japan experiences about 10% of the world’s major earthquakes. The three most seismically active zones relevant to foreigners in Japan are:

Tokyo Metropolitan Area (Kanto Region): The Tokyo Inland Earthquake (首都直下地震) is one of the most anticipated disaster events globally. Scientists estimate a 70% probability of a M7+ earthquake hitting the greater Tokyo area within the next 30 years.

Nankai Trough (Pacific Coast): A megaquake of M8–9 class is considered inevitable along this underwater fault stretching from Shizuoka to Kyushu. The last major event was in 1946; historical cycles suggest the next could occur within 10–30 years.

Hokkaido and Northern Japan: The 2018 Hokkaido Eastern Iburi earthquake (M6.7) caused widespread landslides and blackouts, highlighting vulnerabilities in rural northern areas.

Japan’s Earthquake Warning System (緊急地震速報)

Japan operates one of the world’s most advanced earthquake early warning systems. The Emergency Earthquake Bulletin (EEW) is broadcast seconds before shaking begins via:

• Your smartphone: All mobile phones in Japan (including foreign SIM cards) automatically receive J-ALERT emergency broadcasts. You’ll hear a distinctive alarm tone before an earthquake hits.

• Television and radio: All channels immediately switch to earthquake coverage.

• Public address systems: Sirens and announcements in public spaces, stations, and shopping malls.

Critical point: When you hear the emergency alarm, you typically have 10–60 seconds before shaking begins. Use those seconds — don’t freeze.

Japan’s Seismic Intensity Scale (震度 / Shindo)

What To Do DURING an Earthquake

If You’re Indoors

Drop, Cover, and Hold On. This is the universally recommended action:

1. DROP to your hands and knees immediately. This prevents you from being knocked over.

2. COVER your head and neck with your arms. If possible, get under a sturdy desk or table — move with it if it shifts.

3. HOLD ON until the shaking stops. Earthquakes can last 30 seconds to 3 minutes.

Do NOT: Stand in doorways (a myth from older construction eras), run outside during shaking, or use elevators immediately after an earthquake.

If You’re in a Modern Japanese Building

Buildings constructed after 1981 in Japan must meet the New Seismic Standard (新耐震基準) and buildings after 2000 meet even stricter codes. Most modern apartment buildings and offices in major cities are designed to survive M7+ earthquakes. Trust the building — don’t run outside.

If You’re Outside

Move away from buildings, utility poles, and walls. Look up and protect your head from falling debris. In coastal areas, immediately move to higher ground after the shaking stops — don’t wait for official tsunami warnings.

If You’re on the Tokyo Subway

Hold firmly to handrails and brace against your seat. Trains automatically stop when significant seismic activity is detected. Follow crew instructions — Japanese train staff are extensively trained for earthquake response. Do not attempt to exit the train or use emergency exits while the train is in a tunnel.

Tsunami Risk: The Critical 10-Minute Rule

If you’re in a coastal area and experience a major earthquake (strong or prolonged shaking), assume a tsunami is possible and evacuate immediately — don’t wait for official warnings. The first tsunami wave can arrive in as little as 5–15 minutes after an offshore quake.

Look for blue tsunami evacuation signs (津波避難場所) — these are posted throughout coastal towns across Japan. Elevated ground, tsunami shelters, and reinforced concrete buildings above the 3rd floor are your targets.

Essential Apps for Foreigners in Japan

📱 Safety Tips (by JNTO)

The Japan Tourism Agency’s official disaster information app. Provides real-time earthquake, tsunami, heavy rain, and volcanic eruption alerts in English, Chinese, Korean, Spanish, and more. Download this before you need it.

📱 NHK World Japan

NHK broadcasts English-language emergency news and disaster updates during major events. The app is free and works even on slow mobile connections.

📱 Yahoo! Disaster Alert (Yahoo!防災速報)

Primarily in Japanese but provides location-specific alerts faster than most other apps. Worth having if you’re staying long-term.

📱 Google Maps Offline

Download offline maps of your area before any trip. Cell networks become overloaded during earthquakes; offline maps work without internet.

Your Earthquake Preparedness Kit (非常用持ち出し袋)

Japanese households traditionally prepare a 非常用持ち出し袋 (emergency go-bag). For foreigners in Japan, include:

• Water: 3 liters per person per day, minimum 3-day supply

• Food: Non-perishable snacks, instant noodles (the Japanese stockpile specialty), energy bars

• Passport and residence card copies (keep originals in a waterproof pouch)

• Cash in small bills: ATMs go down after major earthquakes; electronic payments fail. ¥10,000–¥30,000 in cash is recommended

• Phone charger and portable battery

• First aid kit

• Prescription medications (7-day minimum supply)

• Flashlight and whistle (to signal rescuers)

• Emergency contact list in both English and Japanese

• Embassy contact information

Register with Your Embassy

All major countries operating embassies in Japan offer traveler or resident registration programs. In a major disaster, your embassy can:

• Account for your safety

• Assist with emergency evacuation

• Provide emergency passport issuance

• Connect you with welfare officers

Register at your country’s embassy website before disaster strikes. For US citizens: STEP (Smart Traveler Enrollment Program).

Designated Evacuation Shelters (避難所)

Every ward and municipality in Japan designates specific buildings as earthquake evacuation shelters (避難所 — hinanjo). These are typically schools, community centers, and parks. You can find your nearest shelter by:

1. Asking your local ward office (区役所/市役所) for your area’s hazard map

2. Searching on your city’s official website

3. Using the NHK Safety Tips app’s shelter finder

Important for foreigners: Many evacuation shelters are staffed by local volunteers who may not speak English. Download Google Translate with offline Japanese-English capability, and bring a pen and notepad for written communication.

After the Earthquake: What To Do

Immediately after shaking stops:

• Check yourself and others for injuries before moving

• Shut off gas at the meter if you smell gas

• Open doors carefully — frames may be warped and trap you inside

• Exit the building via stairs, not elevators

• Do not use matches or lighters — gas leaks are common

In the hours after:

• Charge your phone immediately if power is still on — outages may follow

• Fill bathtubs with water in case water supply is disrupted

• Listen to NHK World or local radio for official instructions

• Do not use your car — roads must be kept clear for emergency vehicles

• Be prepared for aftershocks — they can be significant and occur for days

Special Note: Foreigner Support at Evacuation Centers

Japan has been actively improving multilingual support at evacuation shelters since the 2011 Great East Japan Earthquake. In 2026, many major cities have:

• Multilingual disaster volunteers (多言語支援センター)

• Simplified Japanese (やさしい日本語) signage alongside English

• Tablet translation devices at major shelters

Tokyo’s disaster prevention website (bousai.metro.tokyo.lg.jp) now operates in English, Chinese, Korean, and several Southeast Asian languages.

Key Japanese Earthquake Vocabulary

Should You Evacuate or Stay Home?

If your building is undamaged and there’s no fire nearby, staying home (在宅避難) is usually best — shelters are crowded and basic. Evacuate if: the building is cracked or tilting, fire is spreading nearby, you’re in a landslide/tsunami zone, or authorities issue an evacuation order. Before leaving, switch off the breaker (prevents fires when power returns) and close the gas valve. Evacuation sites are marked 避難所 (hinanjo) — usually the local elementary school. Everyone is welcome, foreigners included; bring your passport/residence card.

Contacting Family (and Being Contacted)

Phone calls often fail after big quakes, but data (LINE, WhatsApp, Messenger) usually works — send a short “I’m safe” first. Tell family abroad your status before they panic-call. Japan also runs Disaster Message Dial 171 and web171 (English available) for leaving voice/text messages tied to a phone number. Public Wi-Fi named “00000JAPAN” opens for free during major disasters.

The First 72 Hours

Rescue teams prioritize life-saving for ~3 days; shops empty and logistics pause. Plan to self-sustain for 72 hours: 3L of water per person per day, easy food, phone in power-saving mode, and — critically — don’t flush toilets if pipes may be damaged (use emergency toilet bags). Beware of aftershocks near damaged furniture, and verify SNS rumors against NHK or the Japan Meteorological Agency before acting or sharing.

Prepare Today: 5 Things in 10 Minutes

1. Download Safety Tips (JNTO’s official app — quake & tsunami alerts in English) and NHK World. 2. Check nothing heavy can fall on your bed; move or secure it. 3. Put slippers and a flashlight by your bed. 4. Save your local hinanjo location (Google Maps: “evacuation shelter”). 5. Buy 2L water bottles × 6 and some ready-to-eat food. A basic emergency backpack (bōsai set) covers the rest:

Bottom Line: Be Prepared, Not Afraid

Living in or visiting Japan doesn’t mean living in constant fear of earthquakes. The vast majority of earthquakes you’ll experience in Japan are minor — a brief shimmy that sends hanging plants swaying, nothing more. Japan’s building codes, warning systems, and disaster preparedness infrastructure are among the best in the world.

The key is preparation: download the apps, know your nearest shelter, keep a go-bag ready, and register with your embassy. Japan is extraordinarily safe in the day-to-day — and with the right preparation, even a major seismic event doesn’t have to be catastrophic for you personally.
