Earthquakes Are Normal Here. That's Why Japan Is So Good at Them.

Japan records over 200 earthquakes per year. Most you won't feel. Some you'll feel and forget about by lunch. A few will rattle your desk and make you pause. The reason Japan is one of the safest places on earth for earthquakes isn't that they don't happen. It's that the entire country is built to handle them.

Modern buildings are engineered for seismic activity. Building codes were significantly strengthened after the 1981 and refined after the 2011 Great East Japan Earthquake. Coastal communities have upgraded seawalls and mapped evacuation routes. The government runs one of the most advanced earthquake early warning systems in the world.

Your job: prepare, stay calm, know what to do. If you're still getting settled, the Japan arrival checklist is a good place to start before tackling earthquake prep specifically.

The Alert System: You'll Get Warned

Seconds. That's what Japan's earthquake early warning system buys you. Not much, but enough to drop, cover, and protect your head before the shaking hits.

SystemWhat It DoesHow You Get It
Earthquake Early Warning (EEW)5–30 second warning before shaking arrivesAutomatic alert on all Japanese phones: loud alarm, impossible to miss
Japan Meteorological Agency (JMA)Official earthquake/tsunami/typhoon authorityTV, radio, mobile apps, NHK broadcasts
J-AlertNational emergency alert (quakes, tsunamis, civil defense)Broadcast via NHK, municipal loudspeakers, mobile phones
Tsunami WarningImmediate alerts to coastal areasTV, radio, loudspeakers, mobile alerts. Move to high ground immediately.

Note

When the EEW alarm sounds on your phone, you have 5–30 seconds. Don't check the notification. Immediately drop, cover, and hold on. Read the details after the shaking stops.

Apps You Need Before the Ground Shakes

Yahoo! Emergency Alerts (Yahoo!ι˜²η½ι€Ÿε ±) Japan's #1 disaster app. Instant earthquake, tsunami, and heavy rain alerts. Set your home address plus 3 additional locations (office, coworking space, frequent neighborhoods). Drawback: Japanese-only interface, but the alert sounds and seismic intensity numbers are universal.

NHK World App English-language government emergency alerts (J-Alert). Earthquake and tsunami alerts available in 11 languages; app interface supports 19 languages total. Best for non-Japanese speakers. Covers earthquakes, tsunamis, volcanic eruptions, and civil defense alerts. Clean interface, reliable push notifications.

Safety Tips (by Tourism Agency) Multilingual disaster app specifically for foreign residents. Available in English, Chinese, Korean, and more. Provides earthquake alerts, tsunami warnings, and nearby shelter locations. Published by Japan Tourism Agency (MLIT).

Tip

Yahoo! Japan is the fastest alert (Japanese-only, but the alarm is unmistakable). NHK World gives you English-language updates after major quakes. Safety Tips maps your nearest shelter. All three are free, all three are small. Get them before you need any of them.

Your Emergency Kit

Near the front door. Not under the bed, not in a storage closet. If a major earthquake hits at 3am, you are not hunting for it. You're grabbing it on the way out.

Know Your Evacuation Routes

Don't wait for shaking to figure out where you're going. Your first week in a new neighborhood is the time to do this: when it's a curiosity walk, not a scramble. (Still looking for a place? See the Japan housing guide for digital nomads.)

Find your nearest evacuation centers (避難所, hinanjo):

  1. Search Google Maps for "hinanjo" or "避難所" near your address (usually schools and community centers)
  2. Know 2–3 nearest routes (different directions in case one is blocked)
  3. Visit your ward office website. Every ward publishes hazard maps (γƒγ‚ΆγƒΌγƒ‰γƒžγƒƒγƒ—) showing flood zones, tsunami risk areas, and evacuation routes.
  4. Ask your landlord. They'll know the building's designated evacuation point.

Heads up

If you live near the coast, know the tsunami evacuation route specifically. High ground is different from general evacuation shelters. Look for ζ΄₯泒避難 (tsunami hinan) signs in your neighborhood.

When the Shaking Starts: Drop, Cover, Hold On

This is the internationally recommended protocol and what Japan drills every year:

DROP to your hands and knees. This prevents falling and lets you crawl to cover.

COVER your head and neck with your arms. If a table or desk is nearby, get under it.

HOLD ON to your shelter until the shaking stops. Earthquakes can last 10–60 seconds for significant ones.

After the shaking stops:

  1. Put on shoes (broken glass everywhere)
  2. Check for gas leaks (smell). Turn off gas if possible.
  3. Check your phone for tsunami warnings
  4. If building is visibly damaged, exit and go to nearest evacuation center
  5. If building is intact, stay inside. Aftershocks are common.

The Shindo Scale: What Those Numbers Mean

Japan uses the Shindo scale (ιœ‡εΊ¦), not the Richter magnitude. Forget the number you learned in school. This is what you'll see on every alert, TV broadcast, and app notification:

Shindo LevelWhat You FeelWhat To Do
1–2Slight swaying, hanging objects moveNothing. This is normal.
3Noticeable shaking, dishes rattlePause, be aware
4Strong shaking, unstable objects fallDrop, Cover, Hold On
5 LowerLarge objects move, difficult to walkDrop, Cover, Hold On. Take seriously.
5 UpperFurniture falls, wall cracks possibleFull earthquake response
6+Standing impossible, building damage likelyFull earthquake response + prepare to evacuate

Coworking and Cafes: Earthquake Awareness

When working outside your home, take 30 seconds to note:

This is not paranoia. It's the same thing every Japanese person does automatically.
