Japan Earthquake Safety for Tourists — What to Know and What to Do
← Back to Culture, Etiquette & Special Situations
Japan experiences more earthquakes than almost any other country — around 1,500 measurable earthquakes per year, of which most are minor and go unnoticed. The vast majority of visitors to Japan will experience small tremors at most. But Japan's seismic activity is real, the infrastructure is designed around it, and knowing what to do in the event of a significant earthquake before you arrive eliminates the worst-case response: freezing because you don't know what to do. This guide covers what earthquake preparedness actually looks like for a tourist in Japan.
The realistic picture — what tourists actually experience
Most visitors to Japan notice a minor tremor at some point during their trip — a brief shaking that passes in seconds, buildings sway slightly, and Japanese people around you continue without significant reaction. This is the normal earthquake experience in Japan for the vast majority of travelers.
Japan has experienced major earthquakes — the 2011 Tohoku earthquake (magnitude 9.0, the most powerful in recorded Japanese history) and the 1995 Kobe earthquake (magnitude 6.9) caused catastrophic damage and loss of life. These events shaped Japan's earthquake preparedness infrastructure comprehensively. The result is that modern Japanese buildings, particularly those built or renovated after 1981 (when Japan updated its seismic building codes), are among the safest earthquake structures in the world.
Hotels in major tourist areas (Tokyo, Kyoto, Osaka) are subject to strict seismic standards. The risk of a building collapse in a tourist accommodation in a major Japanese city is significantly lower than the popular image of earthquake danger suggests.
Japan's earthquake alert system
Japan has one of the most sophisticated earthquake early warning systems in the world. The system detects P-waves (the initial, less destructive wave) and sends alerts to phones, television, and public address systems before the stronger S-waves arrive — typically giving 5 to 30 seconds of warning before significant shaking begins.
Japan uses its own seismic intensity scale called Shindo (震度, 0–7) rather than the Richter magnitude scale. Shindo measures how strongly the ground shakes at a specific location — Shindo 1 to 3 is perceptible but causes no damage, Shindo 4 causes rattling and minor disruption, and Shindo 5-weak (5弱) or above may require evacuation consideration. When you see earthquake alerts in apps or on Japanese news, the Shindo number tells you the local intensity where you are — more useful than the overall magnitude for deciding how to respond.
What the alert sounds like: a distinctive alarm tone plays on all phones in the affected area simultaneously — a jarring, attention-demanding sound that's impossible to ignore. If you hear this sound on your phone or from other people's phones around you, an earthquake is imminent. The alert message is in Japanese but the sound itself is the warning — act immediately rather than trying to read the notification.
Getting alerts on your phone: Japanese phone numbers (physical SIM cards from Japanese carriers) receive earthquake alerts automatically. eSIM users and tourists on foreign numbers may not receive the alerts depending on carrier and device settings. To ensure alerts on any device:
Download the NHK World Japan app — provides English-language earthquake alerts and news. Download the Safety Tips app (by Japan Tourism Agency) — designed specifically for foreign visitors, provides disaster alerts in multiple languages including English. Both apps are free and should be downloaded before arrival.
NHK World Japan: English earthquake alerts, tsunami warnings, and general emergency news. Available on iOS and Android. Enable push notifications.
Safety Tips (Japan Tourism Agency): multi-language disaster alerts including earthquake, tsunami, and severe weather. Designed for foreign visitors. Available on iOS and Android.
Yahoo! Japan Bosai: Japanese-only but the most comprehensive real-time earthquake data. Useful for checking the magnitude and epicenter of a tremor after it occurs.
What to do during an earthquake
The response depends on the severity of shaking. For minor tremors (what most visitors will experience), the appropriate response is to wait calmly until the shaking stops — typically within 10 to 30 seconds. For stronger shaking:
If indoors:
Drop, cover, and hold on. Get under a sturdy table or desk if one is immediately available. If not, move away from windows, bookshelves, and anything that could fall. Cover your head and neck with your arms. Stay away from exterior walls. Do not run outside during shaking — the risk of injury from falling glass and debris is highest during movement.
In a hotel room: the space beside the bed, against an interior wall, provides reasonable cover. Hotels typically have earthquake response instructions on the back of the door — read these on arrival as a habit, not as an anxious preparation.
If in a high-rise building:
Modern Japanese high-rises are designed to sway during earthquakes rather than resist — the swaying you feel in a tall building during an earthquake is intentional and indicates the building is responding as designed. Stay away from windows. Do not use elevators immediately after significant shaking — take stairs once the shaking has stopped. Modern Japanese elevators are equipped with seismic sensors that automatically stop at the nearest floor and open doors when P-waves are detected — if you are in an elevator during an earthquake, it should stop automatically. If it does not, press all floor buttons to stop at the nearest floor, then use the emergency call button. Do not attempt to force the doors open.
If outdoors:
Move away from buildings, power lines, and anything that could fall. Open spaces (parks, wide streets) are the safest outdoor positions during significant shaking. If near the coast during a significant earthquake, move immediately to higher ground without waiting for an official tsunami warning — the earthquake itself is the warning.
If on the Shinkansen or train:
Japan's rail system has automatic earthquake shutoff systems — trains brake automatically when seismic activity is detected. If a Shinkansen stops unexpectedly, remain seated and follow staff instructions. The train will not resume until the tracks have been inspected. Delays of several hours are possible after significant earthquakes; plan for this when scheduling Shinkansen travel.
After the shaking stops
Check for injuries. Apply first aid if needed. Do not move anyone with a potential spinal injury unless they are in immediate danger.
Check for fire. Gas leaks and fires are the most significant post-earthquake hazard in Japan. If you smell gas, do not use any electrical switches or open flames. Open windows if safe and evacuate. Japan's gas systems have automatic shutoffs that activate during significant earthquakes — but not all leaks are detected automatically.
Expect aftershocks. Significant earthquakes are followed by aftershocks — sometimes immediately, sometimes hours or days later. After a significant earthquake, be prepared for continued shaking and respond the same way as the initial event.
Follow official instructions. NHK World (English broadcast) is the primary official information source during and after major disasters. The Safety Tips app will push government-issued instructions and evacuation orders in English. Follow hotel staff instructions — they are trained in earthquake response specific to their building.
Tsunami awareness: if you are within a few kilometers of the coast when a significant earthquake occurs (magnitude 6.5 or greater), move immediately to higher ground without waiting for an official warning. Japan's tsunami warning system is fast but the time between a major offshore earthquake and tsunami arrival can be as short as 10 to 15 minutes in some locations. Evacuation routes and tsunami hazard zone maps are posted in coastal areas — note them when you arrive at a coastal destination.
Practical preparation before your trip
Know your hotel's evacuation route. Read the emergency instructions in your hotel room on arrival. Note the nearest stairwell and the assembly point. This takes 2 minutes and eliminates one decision in an emergency.
Keep shoes accessible at night. In the event of a nighttime earthquake, broken glass on floors is one of the most common injury sources. Keeping shoes beside the bed rather than across the room means you can put them on immediately before moving.
Keep your phone charged. Your phone is your primary information source during and after an earthquake. Keeping it above 50% charge during the day is practical preparation rather than excessive anxiety.
Know the emergency number. Police: 110. Fire and ambulance: 119. Japan Visitor Hotline (English, 24 hours): 050-3816-2787.
Travel insurance with emergency evacuation coverage. Standard travel insurance covers medical expenses; not all policies cover emergency evacuation. For Japan specifically, a policy that includes emergency evacuation is worth the additional cost — the scenarios where evacuation assistance matters (major disaster in a remote area) are real possibilities given Japan's seismic and volcanic environment.
What Japan's earthquake preparedness means for your trip
Japan's earthquake infrastructure is the most sophisticated in the world precisely because the seismic risk is real and has shaped the country's construction, emergency response, and public behavior for decades. Modern buildings meet standards that no other country requires. Emergency response drills are conducted nationally. The population knows what to do.
For a foreign visitor, the practical preparation is minimal: download two apps, read the hotel emergency instructions, keep shoes accessible, and know the emergency number. Beyond that, Japan's own systems are doing the heavy lifting. The earthquake risk in Japan is real but it is also managed with a seriousness and competence that makes a first-time visitor significantly safer than they would be in an equivalent seismic environment without Japan's preparedness infrastructure.
Still planning your Japan trip dates?
Japan's earthquake risk is real but well-managed — it shouldn't change your plans. What does affect planning is flight price by season. Compare options before committing to dates. Search & compare Japan flights on Aviasales →
