Japan Natural Disaster Alerts: Official Travel Information

JGO! editorial team — WEBMARKS Inc. (Fujisawa, Kanagawa)

Prepare more than one official information route before travelling in Japan. The Safety tips app is designed to provide notifications to visitors, the Japan Meteorological Agency (JMA) publishes hazard information, and the Japan National Tourism Organization (JNTO) provides visitor assistance and links to travel information. These resources serve different purposes: a notification, a current hazard page, a transport update and personal assistance are not interchangeable.

Read any alert together with its stated area, update time and the instructions issued for the place you are visiting. A warning may cover a broad region, while your accommodation and immediate plans concern a particular locality. This guide explains how to find and use the official information routes; it does not report warnings currently in force, test your phone or identify an evacuation place for your accommodation.

Before departure: save several official information routes

Start by saving the official Safety tips page, the JMA English information menu and JNTO’s visitor-assistance and medical-information pages. Keep them somewhere you can reach without searching through a long list of old screenshots, and label each one by its purpose. The official pages were checked for this guide on 5 November 2026; that check date is not a report of current conditions.

The Japan Tourism Agency also distributes a Safety Information Card in English, Chinese and Korean. Save the version you can read confidently from the agency’s travel safety information page. A stored card can be a useful prepared reference, but it is not a live warning page and cannot tell you whether conditions have changed since it was saved.

Before travelling, make the location details you may need easy to find: your accommodation’s name and address, your next destination and the transport booking relevant to that journey. This does not identify the local evacuation arrangements for you, so ask your accommodation about its instructions and keep those instructions connected to its address. If your destination changes, review the information for the new location instead of assuming that details for the previous one still apply.

These routes complement one another rather than providing the same service in different formats. For example, a JMA hazard page is not a transport operator’s service notice, and a stored Safety Information Card is not a current report. Having several routes saved gives you options for checking information, but it does not establish that a particular phone will receive every notification or that a page will be available in every circumstance.

What Safety tips offers visitors

Safety tips is a notification app intended for visitors to Japan. The official app information describes notifications for earthquake early warnings, tsunami warnings and weather warnings; the Japan Tourism Agency’s travel information also identifies volcanic warnings, evacuation information and heat-related information among the app’s notification functions. See the official Safety tips page for the current description and its links to app information.

The app’s described resources go beyond notifications. They include action flowcharts, expressions that can help you obtain information from people nearby, and links to useful disaster information. These features address separate needs: receiving a notice, consulting a response flow and asking a person for information are not the same task. Reviewing the materials in advance can help you recognise what the app offers before you need to use it in an unfamiliar place.

The listed languages include English, Japanese and Korean, as well as Traditional and Simplified Chinese. Vietnamese, Thai and Indonesian are also among the languages listed in the official app information. The agency’s travel page presents its language information differently, so do not combine the two presentations into a single language count. Use the current official app page to check which language options are described.

Follow the official page’s links for current installation information, then review the setup on your own device. The material used for this guide does not establish operating-system compatibility, confirm a successful test notification on your phone or guarantee delivery in every situation. A downloaded app is not proof that a notification route has been configured or tested, and the app description is not a delivery guarantee for every device or network condition.

Use the JMA page that matches your question

The JMA’s English information menu links to several kinds of official information. Its menu includes weather warnings and advisories, typhoon information, risk maps, precipitation nowcasts, daily forecasts and marine warnings. It also links to earthquake information, tsunami warnings and advisories, volcanic warnings, eruption information and ashfall forecasts.

Choose a page according to the question you need answered. A daily forecast and a weather-warning page are different information products; a marine warning is not a notice from a railway or other transport operator. Likewise, pages about different hazards or forecast periods may not describe the same area or time. The JMA menu is an index to these resources, not a single report that answers every travel question.

When you open a page, check the area and update information displayed there before applying it to your plans. Keep the Japanese place name of your accommodation or destination available if you need help matching a notice to a location. A notice covering a large region and information referring to a particular municipality may prompt different location questions; do not assume that a regional heading identifies the conditions at every individual address.

Treat this guide as an explanation of where to look, not as a description of current hazards. For a decision about a journey day, open the current official information and follow the instructions of local authorities and facility staff for the place you are in. A saved screenshot, a creator’s video or the date this article was checked is not evidence of present conditions.

Additional travel information: JNTO, NHK WORLD-JAPAN and official notices

The Japan Tourism Agency’s travel safety information page directs visitors to JNTO’s important notices for weather and transport information. The agency also identifies the Japan Safe Travel X account, @JapanSafeTravel, Chinese-language information on Weibo and NHK WORLD-JAPAN as an English-language source for disaster information. These are additional routes to information, not substitutes for the hazard information or local instructions that apply to a particular place.

The agency page was updated on 27 October 2026, according to the supplied official information checked for this guide on 5 November 2026. That date describes the agency page; it does not establish when any individual notice was last updated or whether a live situation has changed. Check the date, area and nature of the information on the relevant page or account before using it to make a travel decision.

A Safety Information Card and a live update have different roles. A saved card can keep prepared information available, while a current notice is the route to information that may change. Saving the card in a language you can read is useful preparation, but it does not turn the card into a report of present weather, transport operation or local evacuation instructions.

During a disruption, check the named transport operator for the status of the service you intend to use and for information about the particular booking. A national travel notice does not set the refund or ticket-change terms for an individual reservation. For other everyday trip planning, see our Japan bus guide, cash and card guide and Japan budget travel guide; those topics do not replace current hazard or operator information.

Assistance and medical-information links

JNTO’s Japan Visitor Hotline is described as available 24 hours a day, 365 days a year. Its listed scope includes disaster assistance and general tourist information, and the JNTO page lists English, Chinese and Korean support. The official number to call from within Japan is 050-3816-2787; the international-format number is +81-50-3816-2787.

Keep this visitor-assistance service distinct from emergency dispatch. JNTO separately identifies 119 for fire and ambulance emergencies. Save each number with its purpose so that you can tell which service you are contacting; the hotline’s stated role is visitor assistance and tourist information, not a replacement for the emergency number. This guide does not test whether a call can be connected from a particular phone, network or location.

The Japan Tourism Agency page also notes Japanese among the languages associated with hotline information, while the JNTO hotline page lists English, Chinese and Korean. Those descriptions are not identical, so this article keeps the scope of the JNTO page separate rather than presenting a combined language list as if both pages stated the same thing. Check the current official hotline page before travel for its own service information.

JNTO’s medical-information guide provides information for visitors seeking medical institutions, with English, Chinese and Korean information available. Its guidance also directs illness and injury enquiries to consultation services for the prefecture where the visitor is staying. Use the information for the actual location and situation; do not assume that every medical service has identical language arrangements or that one prefecture’s consultation route applies everywhere.

Practical checks for your trip

Before departure, save the official pages you are most likely to need and give them clear labels. Put the accommodation address, destination and relevant booking information somewhere you can access without relying on memory. If you are travelling between locations, update the location details you are using rather than continuing to consult information associated with an earlier stop.

A practical preparation sequence is:

1. Open the official Safety tips page and follow its current links for app information.
2. Review the app’s language and the settings relevant to notifications on your own device.
3. Save the JMA English menu so you can choose the information type that matches your question.
4. Save the relevant English, Chinese or Korean Safety Information Card from the Japan Tourism Agency travel page.
5. Save the JNTO hotline and medical guide, with labels that distinguish visitor assistance, emergency dispatch and medical information.
6. Identify the information page of the transport operator for your booked journey.
7. Ask your accommodation where to find its local instructions, and keep those instructions with the accommodation’s name and address.

These steps organise information; they do not prove that a phone will receive an alert, that a notification setting is correct or that an evacuation plan has been completed. The sources supplied for this guide do not verify the current requirements for each operating system, test an individual device or identify the evacuation place for each property. If you cannot rely on one information route, consult another saved official route where available and follow the instructions from local authorities and facility staff.

Do not treat an old screenshot as a live notice or infer the current situation from the publication date of a travel guide. Reopen the relevant official page and read the area and update information shown. If the place you are visiting changes, review the information for that place and ask the relevant accommodation or facility about its instructions rather than carrying over assumptions from elsewhere.

Creator accounts and common questions

Two creator accounts mentioned in the original guide are Takahashi Suzuki（防災 看護師）, who presents a Nankai megathrust earthquake simulation, and akidearest, who describes experiencing a natural disaster in Japan in a personal account. These accounts can offer a simulation or an individual experience, but neither should be mistaken for a current official warning or a prediction for a particular travel date. Check the date, location and context of a creator’s material before relating it to your own plans.

For present conditions, use the relevant JMA information and current instructions from local authorities or facilities. A simulation is not itself an official warning, and a personal account does not establish what is happening at another place or time. The official sources below are the routes to use for current information and visitor assistance.

Will Safety tips guarantee that I receive an alert?

No. The official description lists notification functions, but the supplied information does not guarantee delivery on every device or under every network or offline condition. Check the app’s current information and your own setup, and keep additional official routes available.

Does the JNTO Japan Visitor Hotline replace 119?

No. JNTO describes the hotline as a visitor-assistance service for disaster support and general tourist information, and separately identifies 119 for fire and ambulance emergencies. Save the numbers with those distinct purposes and check the current official hotline page before your trip.

Which source tells me what is happening right now?

Open the relevant current JMA page, JNTO travel information and any applicable local or facility information for your location. Read the displayed area and update information rather than relying on the date this guide was checked, a stored screenshot or an earlier social-media post. This article does not report which warnings are currently in force.

Where should I go if there is an alert?

This guide cannot identify an evacuation location for every accommodation or destination. Follow the current instructions of local authorities and the facility where you are, together with the official hazard information that applies to that location. Ask your accommodation about its local instructions before you need them and keep the answer associated with its address.

What should I do if I change destinations?

Review the information for the new place instead of assuming that information saved for the previous location still applies. Keep the new accommodation or destination name available so you can check whether a notice refers to the right area. For transport information, consult the operator responsible for the journey you have booked.
