Japan’s typhoon season generally runs from summer into early autumn. If a typhoon is approaching during your trip, you may need to change your plans—but it does not necessarily mean your whole trip is ruined.
What you should do depends a lot on where you are traveling. A typhoon can be very different when you are staying in Tokyo or Osaka compared with traveling through rural Japan or visiting a small island.
Here is what to keep in mind.

Weather Alerts in Japan: Advisory vs. Warning
Japan uses different levels of weather alerts, and you may see 注意報 (Chūihō : Advisory) and 警報 (Keihō : Warning) during a typhoon.
・注意報 (Chūihō : Advisory) means that weather conditions could cause damage, so you should be cautious. In many urban areas, trains and other transportation will usually continue operating under an advisory, although you should still check for updates.
・警報 (Keihō : Warning) means that the risk of serious weather-related hazards is higher. It does not automatically mean that you need to evacuate, but it is a good signal to reconsider unnecessary travel and outdoor activities.
How you should respond also depends on where you are staying.
Driving in heavy rain can be challenging, especially when roads are flooded or visibility is reduced. Check local road conditions before setting out during severe weather.
Where to Get Typhoon Information in English
For the latest information, it is best to check official sources rather than relying only on social media or old travel information.
- Japan Meteorological Agency (JMA) — Official weather warnings, typhoon forecasts, and other weather information.
- NHK WORLD-JAPAN — English-language news and updates about major weather events.
If You’re Staying in a Major City
In a major city such as Tokyo or Osaka, transportation is one of the main things to watch during a typhoon. Trains, subways, and Shinkansen services may be delayed or suspended depending on the weather.
However, don’t assume that an attraction is safe to visit just because it is indoors. Some tourist sites may close without much advance notice, especially temples, shrines, parks, and other places where opening hours can depend on local conditions. Even if your destination is open, getting there may mean walking through strong winds and heavy rain.
If a weather warning (警報, keihō) is in effect in your area, it is generally best to avoid unnecessary outings. You don’t need to evacuate simply because a weather warning has been issued, but it is a good reason to stay somewhere safe and avoid sightseeing.
If you need food or other essentials, a quick trip to a nearby convenience store may be reasonable if conditions allow. Otherwise, stay at your hotel and wait for the warning to be lifted or the weather to improve.
Once the warning has been lifted, you can start considering your plans again. However, the end of a warning does not necessarily mean that all dangerous conditions have disappeared. Strong gusts, flooding, or other hazards may still remain, so continue to check local information before going outside.

If You’re Traveling in Rural or Mountainous Areas
A typhoon can be more disruptive in rural, mountainous, or coastal areas than in major cities.
If a weather warning (警報, keihō) is in effect, avoid unnecessary travel and outdoor activities. In rural areas, however, the risks can be quite different from those in a major city. Heavy rain can cause flooding, landslides, and road closures, while strong winds can affect roads and local infrastructure.
Local trains and buses may have fewer services, and there may be few or no alternative routes if a railway or road is closed. If you are driving, check road conditions before setting out and be prepared for sudden changes.
If you are staying somewhere like Hakone or another mountainous tourist destination, ask your hotel, ryokan, or guesthouse what you should do when a warning is issued. Local accommodation staff are often in a much better position to know about conditions in the immediate area.
Don’t assume that you can simply find another way to your next destination if your original transportation is cancelled. In rural areas, there may be very few alternatives.
And on a day with severe weather, there may not be much you can safely do outdoors anyway. Staying at your accommodation may be the safest—and often the most practical—option.

If You’re Visiting an Island
Island travel requires a little more planning during typhoon season.
Ferries and flights can be cancelled when a typhoon approaches, and there may be only a small number of services each day.
If a typhoon is expected to affect the island, check ferry and flight information early.
If you have an important flight or another reservation on the mainland, consider leaving the island before conditions become severe rather than waiting for the last possible departure.
Once transportation is suspended, you may have to stay on the island until services resume. Even after the weather improves, ferries and small boats may not be able to operate immediately if the waves and sea conditions are still dangerous.
Don’t assume that a sunny day means the next ferry will run. Check with the ferry operator or your accommodation for the latest information before heading to the port.
This is one situation where changing your itinerary early can save you a lot of trouble.
Large waves continue to crash against the cliffs of Yonaguni Island after a typhoon. Even when the weather improves, rough seas can prevent ferries and small boats from operating.
What Happens After the Typhoon?
The weather may improve before transportation returns to normal.
Trains, buses, flights, and ferries can remain suspended or delayed even after the typhoon has moved away. Roads can also be affected by flooding or landslides.
If you are planning to travel to another city immediately after a typhoon, check transportation information again before leaving.
Give yourself extra time if you have an important flight or reservation.
Useful Japanese Words During a Typhoon
You may see these words on transportation websites, signs, or news reports:
| Japanese | Meaning |
|---|---|
| 注意報 (chūihō) | Advisory |
| 警報 (keihō) | Warning |
| 運休 (unkyū) | Service suspended |
| 遅延 (chien) | Delay |
| 欠航 (kekkō) | Flight or ferry cancelled |
| 避難 (hinan) | Evacuation |
| 避難所 (hinanjo) | Evacuation shelter |
Train delays are common during severe weather in Japan. This display shows a delay of several dozen minutes, but major disruptions can sometimes cause delays of two hours or more—or even lead to service suspensions. Always check the latest railway information before traveling.
Final Tips
A typhoon does not automatically mean that you need to cancel your Japan trip. What you should do depends on where you are staying and how severe the weather is.
If a weather warning (警報, keihō) is in effect: avoid unnecessary travel and sightseeing until the warning is lifted. This does not automatically mean you need to evacuate, but it is a good reason to stay somewhere safe and avoid going outside unless necessary.
In major cities: check transportation information and avoid unnecessary outings. Attractions may close without much notice.
In rural or mountainous areas: pay more attention to local transportation, road conditions, and advice from your accommodation.
On islands: check flights and ferries early. Remember that services may remain suspended even after the weather improves if sea conditions are still dangerous.
Most importantly, don’t feel that you have to continue sightseeing just because you have limited vacation time.
Your itinerary can change. Your safety comes first.
