Know which information to watch

Prepare your information plan before bad weather affects transport or power. Save the Japan Meteorological Agency’s official warning information and your municipality’s disaster-prevention page. Check the place names used for your home, workplace and school. A warning for a wider area and a local instruction can provide different parts of the picture.

JMA explains that emergency warnings indicate exceptionally serious risk. Its guidance also makes clear that the absence of an emergency warning does not make conditions safe. Monitor ordinary warnings, advisories and local evacuation information early, especially when someone in your household needs more time to move.

Make the local plan practical

Find the municipality’s hazard information for your address and identify the routes and destinations it recommends for relevant hazards. Check the distinction between an evacuation area and a shelter, because the safest destination can depend on the event. Ask the local office if you do not understand a map or a location’s suitability.

Walk an appropriate route in normal conditions when possible. Think about darkness, stairs, mobility needs and the people who may be away from home. Do not plan to cross a place that is already dangerous to reach a preferred destination. Follow current official instructions and the conditions around you.

Keep essential communication available

Prepare a way to receive information if your usual phone service is unavailable, such as a charged portable battery and a written list of local contact details. Agree with household members how to check in and where to find updates. Keep essential medicines and documents accessible in a way suited to your circumstances.

When an event develops, check timestamps and locations before forwarding information. A dramatic photograph or translated social-media message may concern a different place or an earlier incident. Use the official warning and municipal instruction as the reference for action, and seek help early if you cannot move safely without support. Review your plan after a move or change in the household so that it continues to reflect the routes and needs you actually have.

Ask how your household can receive local evacuation information in an accessible format.
