Earthquake Preparedness in Tokyo for Digital Nomads

Most earthquakes you feel in Tokyo are small and short. They’re over before you’ve decided whether to stand up. The building sways, a door creaks, a hanging cable swings, and then the room goes still again.

The city is built for this, and after a few weeks you stop noticing the little ones. Preparing isn’t about living in fear of the big one. It’s about making the small ones boring, and making the few decisions that matter before the ground ever moves.

If you work remotely and travel light, this looks a bit different than it does for a family in a house. You have less stuff to secure and more freedom to move. On the other hand, you may not know your neighborhood well yet, you may not read the emergency signs easily, and you may be the only person in your circle without people nearby to call.

The good news: a few apps, one small bag, and a couple of habits close that gap quickly.

The city has already done most of the preparing. You can catch up in an afternoon.

What to actually do when the shaking starts

The official advice in Japan is refreshingly simple. Memorize it, because you won’t have time to look it up. Protect yourself first, move second.

If there’s a sturdy desk or table nearby, get under it. If not, crouch low against an interior wall, away from windows and anything that could fall, and cover your head and neck with your arms or a bag. Stay there until the shaking stops.

In ordinary Tokyo quakes, a common way people get hurt is falling objects and broken glass, not collapsing buildings.

Don’t run outside while the ground is still moving. During the shaking, falling glass and signs make the street more dangerous than a modern interior.

Once it stops, if you’re indoors, open a door or window so a warped frame can’t seal you in, turn off any open flame or gas, and put shoes on before you walk around. Broken glass is the most common hazard afterward.

If you’re outside when it starts, get away from walls, vending machines, and power lines, and cover your head. If you’re on a train, hold on and wait. Instructions will come.

Trains stop automatically in larger quakes, and the staff drill for exactly this.

Earthquake early warnings on your phone

Japan has one of the best early-warning systems in the world, and it reaches your phone even if you haven’t installed anything. The nationwide emergency alert goes out through cell broadcast and can sound a loud, unmistakable alarm several seconds to tens of seconds before strong shaking arrives. It works by catching the fast, harmless first waves before the slower, stronger ones get to you.

A few seconds is enough to step away from a window, get under a desk, or stop pouring boiling water. The alarm is jarring the first time, and it’s meant to be. Still, how it behaves varies by phone and settings, so don’t count on always hearing it.

Check that emergency alerts are turned on in your phone settings. Whether a foreign SIM, an eSIM, or a phone bought overseas gets the government broadcast depends on the handset, its settings, and the network. That’s why the Safety tips app below isn’t optional. It’s also a good idea to look up once what the alert sounds like, so the real thing doesn’t just confuse you.

If mobile data gets patchy after a big quake, look for the Wi-Fi network called 00000JAPAN. During major disasters, carriers open their public Wi-Fi under that name for free, with no password. Traffic on it isn’t encrypted, so skip any logins that matter. To let people know you’re safe, NTT’s disaster message board (web171.jp) lets you leave a short text message under a phone number, and it has an English screen.

Pack a small emergency bag

You don’t need a survival bunker. You need a small grab-and-go bag by the door that turns a bad night into an annoying one.

Pack a few liters of water and some food that doesn’t need cooking, a battery pack and cable for your phone, a small flashlight or headlamp, any regular medication, a paper copy of your passport (and your residence card, if you have one; short-term visitors and digital nomad visa holders aren’t issued one), and some cash in small notes, since card readers and ATMs can go down with the power.

A power outage is the disruption you’re most likely to actually face, and it’s the one your work depends on. A charged battery pack, offline copies of key documents, and knowing where your nearest convenience store is will do more for you than any gadget.

Konbini restock fast and stay open through a lot. Often they’re the first sign a neighborhood is getting back to normal.

Learn your building and your ward before you need to

Tokyo uses two similar words for two different places. An evacuation area (hinan basho) is open ground, usually a park, where you go to get away from fire and falling debris. An evacuation shelter (hinanjo) is usually a school, stocked with supplies, where people stay for a while if they can’t go home. Both have standard signs and are listed by your local ward office. Find your nearest one of each on a calm afternoon, and note how you’d walk there.

If you move around a lot, make this part of settling in, along with finding the nearest station and the good coffee.

Your ward office publishes a disaster-prevention map, often with an English guide for residents, and the national and metropolitan governments put out multilingual preparedness handbooks you can skim once. Tokyo’s well-known preparedness guide has an English edition, and it’s actually readable.

Just knowing these exist, and roughly where to find them, gets you halfway there.

The apps worth installing today

A few free apps do most of the work. The government-backed Safety tips app sends earthquake and disaster warnings in English and several other languages, and NHK World runs emergency broadcasts in English during major events. The Tokyo Metropolitan Government’s own app, Tokyo Bousai (東京都防災アプリ), also works in English and includes the city’s disaster guide, maps, and checklists.

A general disaster app that shows nearby shelters on a map makes a good third. Then save a note on your phone with your address in Japanese, so you can show it to anyone if you need directions or help, plus the number of someone back home who’ll want to know you’re OK.

Learn the one word that matters: jishin, earthquake. Public announcements during a quake are usually calm and practical, even if you can’t follow every word. Most of the time, doing what the unbothered commuters around you are doing is the right call.

Preparedness in Tokyo is less about gear and more about having decided in advance, so that when it happens you just do it.

FAQ

Are the earthquakes in Tokyo dangerous day to day?

Almost all the ones you’ll feel are minor and cause no damage. Modern Tokyo buildings are designed to sway and absorb shaking, and everything around you, from train stops to phone alerts, is set up for frequent quakes.

Some basic, sensible preparation covers the realistic risks without taking over your daily life.

Will my foreign phone get earthquake alerts?

Often, but not reliably. The national emergency alert goes to phones on Japanese networks, and whether yours gets it depends on the handset, its settings, and the network. Make sure emergency alerts are turned on.

Installing the Safety tips app gives you English warnings as a reliable backup. Do it especially if you’re on an eSIM.

What is the single most useful thing to do first?

Turn on emergency alerts, install one English disaster app, and find your nearest designated evacuation area. It takes less than an hour and covers early warning, information, and where to go: the three things that are hard to sort out once something is actually happening.
