What Natural Disasters Occur in Japan?
Japan’s location, climate, and mountainous geography expose different parts of the country to different natural hazards.
The main natural disasters travelers should understand are:
| Japanese | Romaji | English |
|---|---|---|
| 地震 | Jishin | Earthquake |
| 津波 | Tsunami | Tsunami |
| 台風 | Taifū | Typhoon |
| 大雨 | Ōame | Heavy rain |
| 洪水 | Kōzui | Flood |
| 土砂災害 | Dosha saigai | Landslide disaster |
| 火山 | Kazan | Volcano |
| 大雪 | Ōyuki | Heavy snow |
The level of risk depends greatly on where and when you travel. Tsunamis mainly affect coastal areas, landslides are more relevant near mountains and steep slopes, and heavy snow is most common in northern Japan and mountain regions.
Most visitors will not experience a serious natural disaster. The important thing is to understand the risks relevant to your destination and know where to find reliable information if conditions change.

Why Japan Has Become More Resilient Over Time
Japan’s disaster preparedness did not develop all at once. It has evolved through experience.
Major earthquakes, tsunamis, typhoons, floods, and volcanic eruptions are studied in detail. Government agencies, researchers, engineers, transportation companies, local authorities, and communities examine where damage occurred and how future losses can be reduced.
It would be inaccurate to say that every disaster automatically results in a new national building law. However, significant events frequently lead to investigations, reviews, technical guidance, policy changes, stronger retrofitting efforts, and improvements to emergency operations.
Building standards have changed over time
Japan’s Building Standard Law was introduced in 1950, and seismic requirements have been strengthened repeatedly.
A major change came in 1981, when the New Seismic Design Standard was introduced following lessons from the 1978 Miyagi-oki earthquake. Buildings approved under older standards may be less earthquake-resistant, although the actual safety of an individual building also depends on its structure, maintenance, ground conditions, renovations, and other factors.
The 1995 Great Hanshin-Awaji Earthquake exposed vulnerabilities in older buildings and urban infrastructure. It was followed by expanded seismic-retrofitting policies and a fundamental review of Japan’s national disaster management framework.
After the 2011 Great East Japan Earthquake and tsunami, Japan reviewed its tsunami assumptions and placed greater emphasis on evacuation, hazard maps, worst-case scenarios, and combining physical defenses with measures that help people escape.
Following the 2016 Kumamoto Earthquake, damage to some wooden homes built after 1981 but before later technical requirements were clarified prompted further investigation and new methods for checking their seismic performance.
The important point for travelers is not that every building is equally safe. It is that Japan continues to study real disasters and use those lessons to improve buildings, infrastructure, warning systems, and emergency procedures.
Disaster preparedness is part of everyday life
Schools, offices, hotels, railway companies, local governments, and community organizations regularly prepare for emergencies.
Evacuation maps are displayed in many public facilities. Railway operators monitor seismic and weather information. Local authorities maintain designated shelters and evacuation areas. Hotels generally provide evacuation information, although the amount of English guidance varies.
This culture of preparation is one reason people may appear calm when an earthquake occurs. Residents and staff are often familiar with basic emergency procedures.
Visitors should follow their lead, listen carefully, and avoid rushing toward an exit without understanding the situation.
Understanding Earthquakes in Japan
地震 / Jishin / Earthquake
Earthquakes are the natural hazard most strongly associated with Japan.
Many earthquakes occur around the Japanese archipelago, but most are either too small to feel or cause no significant damage. A traveler may occasionally notice a short vibration or a slow swaying sensation, particularly on an upper floor.
Feeling an earthquake does not automatically mean that a dangerous event is occurring. The location, depth, duration, ground conditions, building design, and strength of shaking at your particular location all matter.
Magnitude and Shindo are different
Foreign news reports usually focus on magnitude. Japanese reports often emphasize Shindo.
Magnitude measures the overall size or energy of an earthquake. Each earthquake has one magnitude value, although preliminary estimates may later be revised.
震度 / Shindo / Seismic intensity measures how strongly the ground shakes at a particular location.
The same earthquake can therefore produce Shindo 6 in one area, Shindo 4 in another, and only light shaking farther away.
What Do Shindo Levels Mean?
Japan’s Shindo scale helps people understand how strongly the ground is shaking in a particular place.
| Shindo level | What people may experience |
|---|---|
| 1 | Felt slightly by some people who are quiet indoors |
| 2 | Felt by many people indoors; hanging objects may sway slightly |
| 3 | Felt by most people indoors; dishes may rattle |
| 4 | Most people are startled; hanging objects may swing considerably |
| 5 Lower | Many people feel the need to hold onto something stable; unsecured objects may fall |
| 5 Upper | Walking may be difficult without support; unsecured furniture may topple |
| 6 Lower | It becomes difficult to remain standing |
| 6 Upper | Remaining standing is generally impossible; people may need to crawl |
| 7 | Extremely strong shaking; major movement of unsecured furniture and serious structural damage may occur |
These descriptions are general rather than guaranteed outcomes. Actual damage depends on the building, ground conditions, duration and type of shaking, and many other factors. The Japan Meteorological Agency periodically reviews its explanatory table to reflect observed damage and changes in building resistance.
Earthquakes that have reached Shindo 7 since 1995
The table below summarizes earthquakes or earthquake sequences in which Shindo 7, the highest level on the Japanese scale, was recorded.
| Year | Earthquake | Magnitude | Main affected area |
|---|---|---|---|
| 1995 | Great Hanshin-Awaji Earthquake | M7.3 | Kobe and southern Hyogo |
| 2004 | Niigata Chuetsu Earthquake | M6.8 | Central Niigata |
| 2011 | Great East Japan Earthquake | M9.0 | Tohoku and eastern Japan |
| 2016 | Kumamoto Earthquake sequence | M6.5 and M7.3 | Kumamoto and surrounding areas |
| 2018 | Hokkaido Eastern Iburi Earthquake | M6.7 | Central and southern Hokkaido |
| 2024 | Noto Peninsula Earthquake | M7.6 | Noto Peninsula and surrounding areas |
| 2026 | Kumamoto Earthquake | M7.1, provisional | Kumamoto and surrounding areas |
This is not a list of every damaging earthquake in Japan. Earthquakes below Shindo 7 have also caused serious local damage.
The 2016 sequence included two earthquakes that reached Shindo 7 within approximately two days. The magnitude and intensity figures in the table are based on Japan Meteorological Agency records; the 2026 magnitude was still listed as provisional at the time of publication and may later be revised.
The purpose of this table is not to suggest that major earthquakes happen constantly. It shows that severe events occur periodically and that each has contributed to ongoing research, reconstruction, and improvements in disaster preparedness.
What to Do During an Earthquake
If you feel strong shaking, your first priority is to protect yourself from falling objects, glass, and unstable furniture.
If you are inside
- Stay calm and protect your head.
- Shelter under a sturdy table when one is nearby and safe to reach.
- Move away from windows, mirrors, shelves, and tall furniture.
- Do not rush outside while strong shaking is continuing.
- Do not use an elevator.
- Follow instructions from hotel, shop, station, or attraction staff.
- After the shaking stops, check the evacuation route and watch for broken glass or fallen objects.
The Japan Meteorological Agency advises people not to rush outside or toward an exit after receiving an Earthquake Early Warning. Strong shaking may arrive within only a few seconds, and areas close to the source may receive little or no advance notice.
If you are outside
Move away from:
- Glass-fronted buildings
- Signs and roof tiles
- Unreinforced walls
- Vending machines or other objects that could fall
- Utility poles and damaged electrical lines
Do not stand directly beside a building entrance unless staff confirm that it is safe.
If you are on a train or bus
Remain inside unless staff tell you otherwise.
Hold onto a handrail or strap, protect your head if necessary, and wait for instructions. Railway services may stop automatically or be suspended so tracks, bridges, tunnels, electrical systems, and trains can be inspected.
A temporary suspension is often evidence that safety procedures are working—not proof that the railway has been damaged. JMA notes that railways and highways may be stopped for safety confirmation after noticeable shaking, depending on the standards used by each operator.
→ How to Use Trains and Subways in Japan (Complete Beginner Guide)
If you are in an elevator
If possible, press the buttons for nearby floors and leave at the first floor where the doors open safely.
Some elevators have earthquake-control systems and may stop automatically. Do not try to force the doors open or climb out without assistance.
Expect aftershocks
After a large earthquake, additional earthquakes may follow.
Stay away from visibly damaged buildings, steep slopes, cracked walls, and areas closed by authorities. Do not enter a restricted area simply to take photographs.
Earthquake Early Warnings and Smartphones
緊急地震速報 / Kinkyū jishin sokuhō / Earthquake Early Warning
Japan’s Earthquake Early Warning system detects initial seismic waves and attempts to warn people before stronger shaking arrives.
The warning may be distributed through television, radio, public-address systems, mobile services, apps, and other channels. However, it is not an earthquake prediction. Depending on your distance from the earthquake, the warning may provide several seconds to take protective action, arrive at almost the same time as the shaking, or fail to arrive before the shaking begins.
Will an overseas smartphone receive the warning?
Possibly, but it should not be assumed.
Automatic reception may depend on:
- The smartphone model
- The country or carrier for which the device was originally configured
- Its operating system and emergency-alert settings
- The Japanese network to which it is connected
- Whether the roaming, SIM, or eSIM service supports the relevant alert method
Buying a Japanese SIM card or eSIM does not by itself guarantee that an overseas phone will receive every emergency alert.
Travelism therefore recommends using an additional official information source rather than relying only on your phone’s built-in alert function.
Tsunamis
津波 / Tsunami / Tsunami
A tsunami is a series of waves that can be generated by a powerful undersea earthquake or other major disturbance.
Most earthquakes do not cause a tsunami. However, when you are near the coast, the correct response to a strong or long earthquake is especially important.
What to do near the coast
If you feel strong shaking or prolonged shaking near the sea:
- Move away from the beach immediately.
- Leave rivers, ports, and waterfront areas.
- Go to higher ground or a designated tsunami evacuation building.
- Follow signs and local instructions.
- Do not wait beside the water for an official warning.
- Do not return until the warning or advisory has been lifted.
Tsunamis can arrive more than once, and a later wave may be larger than the first. Coastal and riverside areas should be avoided until authorities announce that it is safe.
Useful signs include:
津波避難タワー
津波避難経路
| Japanese | Romaji | English |
|---|---|---|
| 津波避難場所 | Tsunami hinan basho | Tsunami evacuation area |
| 津波避難ビル | Tsunami hinan biru | Tsunami evacuation building |
| 高台 | Takadai | Higher ground |
| 避難 | Hinan | Evacuation |
| 立入禁止 | Tachiiri kinshi | No entry |
Tsunami risk is mainly relevant to coastal and riverside locations. It is not a reason to avoid all coastal destinations, but you should identify the evacuation route when staying close to the sea.
Typhoons
台風 / Taifū / Typhoon
Typhoons are tropical cyclones that can bring strong winds, heavy rain, rough seas, and transportation disruption.
Typhoons can develop at different times, but activity affecting travel in Japan is most relevant during summer and autumn. Historical JMA data show that tropical cyclone formation is generally concentrated between July and October, particularly around August and September.
Unlike earthquakes, typhoons are monitored and forecast before arrival. Travelers often have time to adjust their itinerary.
Possible travel effects
- Flight delays or cancellations
- Ferry cancellations
- Train suspensions
- Closed attractions
- Closed mountain trails
- Road restrictions
- Changes to festivals or outdoor events
欠航
計画運休 / Keikaku unkyū / Planned service suspension means that a railway operator intends to suspend services in advance because dangerous weather is expected.
Do not wait until the last train before changing locations. When a planned suspension is announced, services may become crowded before they stop.
What to do when a typhoon is forecast
- Check your airline and railway operator directly.
- Ask your accommodation whether the area is likely to be affected.
- Avoid beaches, rivers, breakwaters, and mountain trails.
- Do not travel simply because a train or flight still appears to be operating.
- Keep food, water, medication, and a charged phone available.
- Allow an extra day in your itinerary when traveling during the main typhoon season.
A typhoon does not necessarily affect all of Japan. Conditions in Okinawa, Kyushu, Osaka, Tokyo, Hokkaido, and other regions may be completely different on the same day.
Check the specific places on your itinerary rather than treating Japan as one weather zone.

→ Best Time to Visit Japan
Heavy Rain, Flooding, and Landslides
大雨 / Ōame / Heavy rain
洪水 / Kōzui / Flood
土砂災害 / Dosha saigai / Landslide disaster
Heavy rain may occur during the rainy season, around typhoons, or when weather systems remain over the same area.
Because much of Japan is mountainous, intense or prolonged rain can create landslide risks. Rivers can rise quickly, and flooding may affect roads, railway lines, and low-lying neighborhoods.
Travelers should avoid
- Riverbanks and dry-looking channels during heavy rain
- Underpasses that may flood
- Mountain paths and steep slopes
- Closed hiking trails
- Areas behind barriers or warning signs
JMA publishes warnings and real-time risk maps for heavy rain, flooding, and landslides. When an evacuation instruction applies to your location, follow staff or local authorities rather than waiting to see whether conditions become worse.
If you are staying in a traditional inn, rural guesthouse, mountain lodge, or vacation rental, ask the host whether the property is near a river, coastline, or steep slope and where you should go if an evacuation is announced.
Where you stay shapes your experience of Japan, but location also determines which natural hazards are relevant. A little local knowledge is more useful than general anxiety.
Volcanic Activity
火山 / Kazan / Volcano
Japan has many volcanoes, including well-known destinations such as:
- 富士山 / Fujisan / Mount Fuji
- 箱根山 / Hakoneyama / Mount Hakone
- 阿蘇山 / Asosan / Mount Aso
- 桜島 / Sakurajima / Sakurajima
The presence of a volcano does not automatically make a destination unsafe.
The Japan Meteorological Agency monitors volcanic activity and issues warnings or alert levels. Depending on the situation, authorities may restrict access to a crater, mountain trail, road, or surrounding area while everyday life continues normally outside the restricted zone.
Travelers should:
- Check the current volcanic alert before hiking.
- Respect trail closures and exclusion zones.
- Do not cross ropes, gates, or warning signs.
- Follow instructions from park staff, ropeway operators, guides, and accommodation providers.
- Understand that access conditions may change even when nearby towns remain open.
An access restriction is a safety measure. It does not necessarily mean the entire region is dangerous or closed.
Heavy Snow and Winter Weather
大雪 / Ōyuki / Heavy snow
Heavy snow can disrupt transportation in Hokkaido, Tohoku, Hokuriku, the Japanese Alps, and other mountain regions.
Travelers may encounter:
- Delayed or canceled trains
- Closed roads
- Limited bus services
- Reduced visibility
- Icy streets
- Temporary closure of mountain attractions
Wear shoes with suitable grip, allow extra travel time, and check local transportation before making a long winter journey.
Cities such as Tokyo, Kyoto, and Osaka receive less regular heavy snow than northern and mountain regions, but even a moderate snowfall can disrupt transportation where snow is less common.
How Accommodation Affects Disaster Safety
Your accommodation is more than a place to sleep. Its location, building type, staff support, and available information can affect how easily you respond during an emergency.
When you check in:
- Identify the nearest emergency exit.
- Read the evacuation map on the door or wall.
- Check whether stairs can be reached without an elevator.
- Keep shoes, your phone, and a small light within reach at night.
- Save the property’s address and contact details offline.
- Ask where to evacuate if the property is near the coast, a river, or a steep slope.
非常口案内
Large hotels often have staff and established multilingual procedures. Smaller inns, private rentals, and rural accommodations may offer a more local experience but may have less English signage.
That does not necessarily make them unsafe. It means travelers should take a little more responsibility for understanding the building and surrounding area.
Staying in a neighborhood rather than a major hotel district can provide a deeper experience of everyday Japan. Knowing the local evacuation point is one small part of traveling thoughtfully.
Reliable Emergency Information for International Travelers
During a disaster, use official information rather than unverified social media posts.
Safety tips
Safety tips is a disaster-information app developed for people traveling or living in Japan. It provides information including earthquake early warnings, earthquake information, weather information, and other emergency notices in multiple languages. The app is available in 15 languages, including Japanese and English.
Because phone compatibility and alert delivery vary, install and configure the app before an emergency occurs.
Japan Safe Travel Information
JNTO’s Japan Safe Travel Information website provides current information for international visitors, including significant earthquakes, tsunami warnings and advisories, volcanic alerts, transportation links, and emergency support.
NHK WORLD-JAPAN
NHK WORLD-JAPAN provides English-language news and emergency reporting through its website and app.
Japan Meteorological Agency
JMA publishes earthquake, tsunami, weather, flood-risk, and volcanic information. Some pages are available in multiple languages.
Ask the people around you
Also pay attention to:
- Hotel and accommodation staff
- Railway and airport announcements
- Station information counters
- Tourist information centers
- Police officers and local authorities
- Public-address announcements
Do not continue moving simply because you do not understand an announcement. Ask:
“Is it safe to leave?”
or
“Where should I go?”
Emergency Numbers and Visitor Support
| Service | Number |
|---|---|
| Service | Number |
| Police | 110 |
| Fire and ambulance | 119 |
| JNTO Japan Visitor Hotline, from Japan | 050-3816-2787 |
| JNTO Japan Visitor Hotline, from overseas | +81-50-3816-2787 |
The JNTO Japan Visitor Hotline operates 24 hours a day and provides assistance in English, Chinese, and Korean in cases including accidents and disasters.
When calling 110 or 119, clearly state:
- What happened
- Your location
- Whether anyone is injured
- The name of your hotel, station, landmark, or nearby shop
Ask hotel staff, station staff, or someone nearby to help if communication is difficult.
What to Keep With You
You do not need to carry a full emergency kit while sightseeing.
A few ordinary travel items can make an unexpected delay much easier to manage:
- A charged phone
- A portable power bank
- Essential medication
- A small amount of drinking water
- Comfortable walking shoes
- Your accommodation address
- A copy or photo of your passport details
- Travel insurance information
- A small amount of Japanese yen
These items are useful during transportation delays as well as emergencies.

Travel Insurance and Flexible Planning
Travel insurance is strongly recommended for international travel.
Before purchasing a policy, check whether it covers:
- Emergency medical treatment
- Trip interruption
- Delayed or canceled transportation
- Additional accommodation
- Natural disasters
- Evacuation or repatriation when medically necessary
Coverage and exclusions differ significantly. Do not assume that every policy automatically covers earthquakes, typhoons, or an itinerary change made before an official cancellation.
It is also helpful to avoid planning an itinerary with no spare time. One flexible day can make a major difference if bad weather temporarily affects transportation.

Frequently Asked Questions
Is Japan safe to visit despite earthquakes?
Yes, Japan remains a practical destination for international travelers, but earthquakes are a real hazard and no trip can be guaranteed to be risk-free.
Modern construction requirements, extensive monitoring, emergency procedures, and regular preparedness efforts help reduce risk. Travelers should understand basic earthquake safety and follow official guidance.
How often will I feel an earthquake in Japan?
There is no reliable way to predict whether you will feel an earthquake during a particular trip.
Many visitors feel none. Others may experience light shaking. A serious earthquake affecting your itinerary is much less common than the small earthquakes recorded around Japan.
Should I leave my hotel during an earthquake?
Do not rush outside while strong shaking is continuing.
Protect your head, move away from glass and unstable objects, and follow hotel instructions. After the shaking stops, use the stairs and evacuate only when necessary or instructed.
Are older hotels unsafe?
Not necessarily.
Building age alone does not determine safety. Construction type, renovations, maintenance, seismic retrofitting, ground conditions, and compliance at the time of construction all matter.
Travelers cannot accurately assess a building’s structural safety from appearance alone. Ask the accommodation about evacuation procedures when you have concerns.
Will my overseas phone receive an earthquake warning?
It may, but automatic reception is not guaranteed.
Compatibility can depend on the device, settings, operating system, network, SIM, eSIM, and roaming arrangement. Use an official disaster-information app and pay attention to local announcements as a backup.
Does buying a Japanese SIM guarantee emergency alerts?
No.
A Japanese SIM or eSIM provides local mobile connectivity, but the phone itself and the service must also support the relevant emergency-alert system.
Should I cancel a trip during typhoon season?
Not automatically.
A typhoon may affect only part of Japan, and its route can change. Monitor official forecasts, keep your schedule flexible, and follow transportation and accommodation guidance.
What should I do if my train stops after an earthquake?
Remain calm and wait for instructions.
Railway operators may suspend services to inspect tracks, bridges, tunnels, signals, and electrical equipment. Do not leave the train or enter the tracks unless staff direct you to do so.
Is Mount Fuji dangerous because it is an active volcano?
Mount Fuji is an active volcano, but it is monitored.
Check current alerts and climbing conditions before visiting. If access is restricted, follow the restrictions and choose another activity in the region.
Should I worry about a tsunami in Tokyo, Kyoto, or Osaka?
Tsunami risk depends on your precise location rather than the city name alone.
Central Kyoto is inland. Parts of Tokyo and Osaka are near bays, rivers, or low-lying coastal areas, while many neighborhoods are farther from the immediate shoreline.
When staying near the coast, learn the evacuation route and follow official tsunami warnings.
What is the most important thing to remember?
Protect yourself first, follow official instructions, and do not make decisions based on rumors.
Japan’s systems work best when people remain calm and cooperate with temporary closures, evacuations, and safety inspections.
Travel With Confidence
Natural disasters are part of Japan’s geography and climate. Pretending otherwise would not help travelers prepare.
However, Japan’s story is not simply that disasters occur here.
It is also the story of a country that investigates what happened, rebuilds, revises its systems, and tries to become more resilient after every major event.
Building standards have evolved. Older structures have been retrofitted. Warning technology has advanced. Tsunami planning has changed. Transportation operators stop services to protect passengers. Communities practice how to evacuate and support one another.
This continuous process cannot remove every risk, and emergencies may still cause serious damage. But it gives travelers something more useful than a promise that nothing will happen: a clear system to follow when plans change.
Understand the basic hazards. Check the conditions for the places you are visiting. Learn the evacuation route where you are staying. Keep your phone charged, follow official guidance, and allow some flexibility in your itinerary.
With that preparation, you can experience Japan beyond its famous sights—staying in local neighborhoods, exploring regional landscapes, and connecting with the culture and everyday life of each place—with greater awareness and confidence.
