🧳 For travelers & visitors to Japan — free, no sign-up

Your earthquake evacuation site
may be ✕ for floods.

Of Japan's 115,000+ designated emergency evacuation sites,
about 40% are not designated for floods.

In Japan, evacuation sites are designated separately for each disaster type.
Check where to go near your hotel or home — for floods, tsunami, earthquakes and more.

🆘 Three things to know before you need them

  • Free disaster Wi-Fi「00000JAPAN」: after a major disaster, carriers may open a free Wi-Fi network with SSID 00000JAPAN (no password). It is unencrypted — use it for information, avoid logins and payments.
  • Emergency calls: 110 police ・ 119 fire & ambulance ・ Japan Visitor Hotline (JNTO) 050-3816-2787 — 24h, English/Chinese/Korean.
  • If every phone suddenly blares an alarm: that is an official earthquake/evacuation alert. Protect yourself first, then follow locals and staff.

Good to know

Why does the same place show ✅ and ❌?

Japanese evacuation sites are designated per disaster type. A school yard can be a good refuge in an earthquake but sit inside a flood-inundation zone — so it may be ✅ for earthquakes and ❌ for floods. Always check the tab for the disaster you face.

What should I do when an alert sounds?

Follow instructions from the municipality and hotel staff first. For an earthquake: drop, cover, hold on — then check this map. For a tsunami warning near the coast: move to high ground immediately, do not wait. For heavy rain/floods: evacuate early, before roads flood.

Place names are in Japanese — how do I use them?

Site names come from official data and are in Japanese, but you can search in English (e.g. “Shinjuku”, a hotel area, a landmark). Use the Directions button for walking navigation, or show this screen to hotel staff or locals — they can read the name and point you the right way.

Is this an official government service?

No. NIGEDOKO is a free independent tool built on official open data (Geospatial Information Authority of Japan and the national hazard-map portal). It is reference information — in an actual disaster, always follow official evacuation alerts.
