Earthquake Safety Guide for Foreigners in Japan | Preparation, Action & Evacuation Essentials

Quick Facts About Earthquakes in Japan

Understanding Earthquakes in Japan: Essential Knowledge for Foreigners

If you’re planning to live, work, or travel in Japan, understanding earthquake safety is not just practical—it’s essential. Japan sits on the Pacific Ring of Fire, where tectonic plates collide beneath the surface. As a foreigner in Japan, you may feel anxious about earthquakes, but knowledge and preparation can significantly reduce your risk and help you respond effectively when tremors occur.

This comprehensive guide covers everything you need to know about earthquake safety in Japan, from preparation and warning systems to the correct actions during and after an earthquake.

The Earthquake Landscape in Japan

Why Japan Experiences So Many Earthquakes

Japan’s location along the Pacific Ring of Fire makes it extraordinarily seismically active. The country sits above four major tectonic plates: the Pacific Plate, the Philippine Plate, the North American Plate, and the Eurasian Plate. As these plates continuously shift and collide, they release energy in the form of earthquakes.

Approximately 1,500 felt earthquakes occur in Japan annually. Most are minor tremors that cause little concern, but the constant activity means that earthquakes are simply part of life in Japan. This high frequency has made Japan a global leader in earthquake science and safety technology.

The Shindo Scale vs. Richter Scale

A crucial point for foreigners: Japan does not use the Richter scale that most people are familiar with. Instead, Japan uses the Shindo (震度) scale, which ranges from 0 to 7. This is a critical distinction because the Shindo scale measures earthquake intensity—the actual impact and damage at specific locations—rather than the energy released by the earthquake.

Here’s what each Shindo level means:

Modern Japanese Building Standards

One reason foreigners in Japan can feel relatively safe is because of the country’s remarkably strict building codes. Japan’s 1981 seismic building codes were revolutionary and have been continuously updated. Buildings constructed after 1981 are engineered to withstand significant seismic activity. This means that if you’re in a modern building, your structural safety is typically very high, even during strong earthquakes.

Before an Earthquake: Preparation is Key

Create Your Earthquake Emergency Kit

Preparation is your first line of defense. Your emergency kit should include:

• Water: At least 1 liter per person per day, for at least 3 days
• Non-perishable food: Items that require no cooking (crackers, canned goods, energy bars)
• First aid kit: Bandages, pain relievers, any personal medications
• Flashlight: Keep it accessible and test batteries regularly
• Battery-powered or hand-crank radio: For emergency broadcasts
• Sturdy shoes: Earthquakes create broken glass and debris
• Important documents: Copies of passport, visa, insurance papers in waterproof bag
• Cash: ATMs may be non-functional after a major earthquake
• Phone charger: Portable battery backup recommended
• Whistle: For signaling if trapped

Secure Your Surroundings

In your home or workplace, take these precautions:

• Bolt heavy furniture: Bookcases, dressers, and refrigerators should be anchored to walls
• Install cabinet latches: Prevent cabinet doors from flying open and spilling contents
• Secure mirrors and pictures: Use earthquake-resistant hanging hardware
• Know the hazards: Identify potential falling objects in your workspace and home
• Plan exit routes: Know multiple ways to safely exit your building

Many of these safety items are available at Japanese home improvement stores (like Cainz or Home Depot Japan) and online retailers.

Download Earthquake Safety Apps

Japan offers several excellent apps to help you stay informed:

• JNTO Safety Tips: The official Japan National Tourism Organization app with multilingual earthquake safety information
• NHK World: Offers earthquake information in multiple languages
• Local municipal disaster apps: Many cities have apps that send emergency alerts in English

Make sure notifications are enabled on your smartphone so you receive alerts immediately.

Understanding Earthquake Early Warning System

How the Earthquake Early Warning System Works

One of Japan’s most impressive technological achievements is the Earthquake Early Warning system (緊急地震速報). This system can provide several crucial seconds of warning before strong earthquake shaking reaches your location.

Here’s how it works:

The key advantage of this system is that it can provide 3 to 30 seconds of warning depending on your distance from the epicenter. These seconds can be the difference between serious injury and safety. The Japan Meteorological Agency (JMA) continuously monitors earthquake activity and updates this system.

Where to Get Official Earthquake Information

For reliable, current earthquake information, visit these official sources:

• Japan Meteorological Agency (JMA): Official government source for earthquake data, tsunami warnings, and Shindo intensity information
• U.S. Embassy Japan Emergency Services: Useful for English-speaking foreigners seeking emergency guidance

During an Earthquake: The Drop, Cover, Hold On Protocol

Immediate Action: Drop, Cover, Hold On

The moment you feel significant earthquake shaking, follow this three-step protocol that is taught to all Japanese schoolchildren:

1. DROP: Drop to hands and knees immediately
2. COVER: Take cover under a sturdy table or desk, or against an interior wall, and cover your head and neck with your arms
3. HOLD ON: Hold on to your protection until the shaking stops (which typically lasts 30-60 seconds)

This protocol is FAR more effective than “standing in a doorway,” which is a common but dangerous misconception. Tables and interior walls provide much better protection from falling objects and structural movement.

Specific Scenarios: What to Do In Different Locations

At Home or Indoors

• Drop, cover, and hold on under a sturdy table
• If no table is available, crouch against an interior wall, away from windows
• Protect your head and neck with your hands
• Do not run outside (falling debris and broken glass are outside)
• Stay under cover until shaking completely stops

At Work or in an Office Building

• Move away from windows immediately
• Drop under your desk and hold on
• If no desk, crouch against an interior wall or in a corner
• Wait for official instructions or all-clear signals before moving
• Japanese workplaces often conduct earthquake drills; participate actively to learn your building’s evacuation routes

Outside on the Street

• Move away from buildings, power lines, and trees
• Drop to the ground in the middle of the street (away from overhead hazards)
• Protect your head and stay low
• Avoid running, as loss of balance is common during earthquakes
• Do not rush to enter buildings

In a Vehicle

• Pull over safely to the side of the road
• Remain in the vehicle with seatbelt fastened
• Avoid stopping under overpasses or power lines
• Once shaking stops, turn off the engine and proceed carefully
• Listen to radio for traffic updates and road damage information

In a Train or Subway

• Hold onto handrails or poles firmly
• Do not attempt to move around or exit
• Brace yourself against walls or seats
• Follow conductor instructions
• Japanese trains are designed to automatically slow and stop during earthquakes

Misconceptions About Earthquake Safety

Myth #1: Stand in a Doorway for Protection

This is false and dangerous. Modern earthquake research has conclusively shown that standing in doorways provides minimal protection. In fact, doorways offer no advantage over other locations in a building. During an earthquake, falling objects from furniture, fixtures, and debris pose greater hazards than structural collapse in modern Japanese buildings. Your priority is to get under a sturdy table or desk, not to find a doorway.

Myth #2: Run Outside Immediately During an Earthquake

This is dangerous. Running outside during an earthquake puts you at risk of falling from buildings, being struck by falling debris, power lines, or broken glass. Modern Japanese buildings are designed to withstand earthquakes. You are much safer staying inside a building and taking cover under a table until shaking stops. Running creates additional risk of falling due to loss of balance.

Myth #3: Earthquakes Can Be Predicted

Currently impossible. Despite decades of research, scientists cannot reliably predict earthquakes. The Early Warning system detects earthquakes already in progress and alerts you to incoming shaking—this is not a prediction. This is why preparation and knowing how to respond are so critical.

Myth #4: Aftershocks Are Always Smaller Than the Main Earthquake

Not always true. Occasionally, what was thought to be the main earthquake is actually a foreshock, and a larger earthquake follows. This is rare but does happen. Always treat significant aftershocks seriously and use the same Drop, Cover, Hold On protocol.

After an Earthquake: Safety and Recovery

Immediate Post-Earthquake Actions

Once the shaking stops, do not immediately rush outside. Follow these steps:

1. Check yourself and others: Assess for injuries. Provide first aid if needed.
2. Check your building: Look for obvious damage like cracks, gas leaks (smell of rotten eggs), or water damage
3. Turn off utilities if unsafe: If you smell gas or see damage, turn off the gas valve at the meter
4. Exit carefully: Watch for broken glass, debris, and aftershocks. Wear sturdy shoes.
5. Stay away from hazards: Avoid downed power lines, damaged buildings, and debris fields
6. Listen to emergency broadcasts: Check your phone or radio for official guidance

Evacuation Shelters in Japan (避難所)

After a major earthquake, local authorities open evacuation shelters (避難所). These are typically:

• Schools and community centers (公民館)
• Gymnasiums and sports facilities
• Parks and outdoor spaces
• Government buildings

Evacuation shelters provide:

• Safe spaces away from damaged buildings
• Basic medical care
• Information and official updates
• Coordination with emergency services

To find nearby shelters, ask local residents, police officers, or check local government websites which typically have shelter locations listed in English.

Contacting Family and Friends

After a major earthquake, phone lines become congested. Japan offers emergency communication services:

• Dial 171: Japan’s Emergency Telephone Information Recording system. You can record a message or listen to messages from people trying to reach you
• Email and messaging apps: Usually more reliable than voice calls during emergencies
• Consulate contact: If you need assistance, contact your country’s embassy or consulate in Japan

Choose: Essential vs. Optional Earthquake Preparations

What You Absolutely Need (Essential)
