Japan has two emergency numbers, both free, both answered around the clock. The complication is modern: a large share of visitors now arrive on a data-only travel eSIM, and a data-only line cannot dial them. That is worth understanding before the day you need it rather than during.
The numbers
- 110 — police. Crime, traffic accidents, lost property that may have been stolen.
- 119 — fire and ambulance. Same number for both.
- 118 — coast guard. Anything at sea.
- Free from any payphone, no coin, no card.
- A data-only eSIM cannot call them. Neither can an internet calling app.
119 covers the ambulance
Visitors from countries with separate fire and medical numbers reliably get this wrong. In Japan the fire department operates the ambulance service, so one number does both. Say which you need at the start of the call.
Ambulances are free at the point of use in Japan. Treatment afterwards is not, which is a travel insurance question rather than a reason to hesitate about calling.
The data-only problem
Travel eSIMs sold for Japan are overwhelmingly data-only. They give you internet and no phone number, and they carry no voice service at all. Dialling 110 from that line does not connect.
Internet calling apps do not fill the gap either. They route through the internet rather than the phone network, so they cannot pass your location to a Japanese emergency dispatcher and generally cannot reach the emergency service at all. Do not plan on one.
| What you are carrying | Can you dial 110 or 119? |
|---|---|
| Home SIM, roaming enabled | Yes |
| Home SIM, roaming off, no credit | Yes — emergency calls bypass this |
| Japanese voice SIM | Yes |
| Data-only eSIM, no other SIM | No |
| Pocket wi-fi only, no SIM in phone | No |
| Any payphone | Yes, free |
The fix costs nothing
Keep your home SIM in the phone and switched on, with its mobile data turned off. Data runs on the cheap Japanese eSIM; the voice line stays available for emergencies. This is the standard dual-SIM setup described in the eSIM installation guide, and it is the single reason not to remove your home SIM for the trip.
Travelling with a phone that has no SIM at all, on pocket wi-fi, leaves you with payphones as the fallback. That is workable, but it means knowing where one is.
Payphones still exist, and they are the backup
Japan kept a public payphone network long after most countries dismantled theirs, specifically because it keeps working when mobile networks fail in an earthquake. You will find them in stations, convenience stores, hotel lobbies and on street corners.
- Emergency calls are free. No coin, no card. Many phones have a red button to press first; on newer models you simply lift the handset and dial.
- Ordinary calls take ¥10 coins or a prepaid telephone card. Older green and grey phones take both.
- They work during network congestion, which is exactly when you would want one.
Making the call in English
Operators on 110 and 119 speak Japanese by default. Both services have access to interpretation, but connecting it takes time you may not want to spend, so make the first few seconds count.
- Say which service you need immediately: “ambulance” or “police”. Both words are understood.
- Give the location before anything else. Read the address off a building plate, a vending machine, or a utility pole — Japanese poles carry the local address on a plate. A nearby convenience store name and branch works too.
- Speak slowly and stay on the line. Do not hang up to look something up.
Two numbers worth saving before you travel
The Japan Visitor Hotline, run by the national tourism organisation, answers in English, Chinese and Korean 24 hours a day on 050-3816-2787. It handles accidents, illness, lost property and general trouble, and it is the right call when the situation is serious but not an emergency. The AMDA International Medical Information Center helps find English-speaking doctors and interprets during consultations.
Ordinary dialling
| Calling | Dial |
|---|---|
| A Japanese number, from inside Japan | The number as printed, leading 0 included |
| A Japanese number, from abroad | +81, then the number without its leading 0 |
| Home, from a Japanese phone | Your country code, then the number |
| Emergency, from any phone | 110 or 119, no prefix |
Numbers beginning 0120 or 0800 are freephone within Japan and usually cannot be reached from a foreign mobile roaming, which catches people trying to call a hotel or a lost property line.
Lost property is a phone call, and it works
Japan’s lost property system recovers a remarkable proportion of what goes missing. Items left on a train go to the station’s lost property office, then to a central office after a day or two. Items found on the street are handed to the nearest police box.
A police box, or koban, is a small staffed police post, and it is the right first stop for anything lost, for directions, and for reporting something minor. There is no need to call 110 for a lost wallet — walk into a koban instead.
If you need to make calls at all regularly, weigh a voice-capable local SIM against the data-only default. The connectivity comparison sets out what each option costs and what it does.
