Traffic Accident in Japan: What to Do and What to Say in Japanese

After any traffic accident in Japan, even a small one, stop, help anyone who is hurt, make the scene safe and report it to the police by calling 110; call 119 for an ambulance. Then exchange details with the other party, call your insurance company, and do not agree to settle anything on the spot.

What you need to know

An accident is stressful in any language, and in a second language the stress takes away words you normally know. The good news is that the steps in Japan are clear and the calls follow set patterns: the 110 operator asks whether it is an incident or an accident, the 119 operator asks whether it is a fire or an ambulance, and both then ask where you are. Reporting to the police is a legal duty for drivers, including cyclists, and the police report is what makes the official accident certificate, which insurers use, possible later. This guide goes through the steps in order, with the Japanese for each call, the details to exchange, what the police officer will ask, how to talk to your insurer, and what is different when you are on a bicycle or on foot. It is calm, practical orientation, not legal advice; your insurer and the police are the people who handle your case.

Stop, help the injured, make the scene safe, then call 110

Call 119 for injuries; say kyūkyū desu and give the location

Exchange names, phone numbers, plates and insurers; settle nothing on the spot

Cyclists have the same duty to stop and report as car drivers

The four lines that matter most

In the first minute you need only a few words: to check on the other person, to report an accident, to ask for an ambulance and to ask someone to call the police. Short, clear words are better than perfect sentences.

Four picture cards: asking if someone is all right, reporting an accident, asking for an ambulance and asking for the police.
Check, report, ambulance, police: four lines for the first minute.
JapaneseRomajiMeaning
大丈夫ですか?Daijōbu desu ka?Are you all right?
事故です。Jiko desu.There's been an accident.
救急車を呼んでください!Kyūkyūsha o yonde kudasai!Please call an ambulance!
警察を呼んでください。Keisatsu o yonde kudasai.Please call the police.

The steps, in order

Japanese law sets out the duties of a driver involved in an accident: stop, help the injured, prevent further danger and report to the police. In practice the order looks like this.

  • Stop the vehicle where it is safe, switch on the hazard lights, and set up a warning triangle if you have one, especially on fast roads. On an expressway, get behind the barrier.
  • Check for injuries. If anyone is hurt, call 119. Do not move an injured person unless there is immediate danger.
  • Call 110 and report the accident, even if it is small.
  • Exchange details with the other party and take photos of the vehicles, the position and the road.
  • Wait for the police, answer their questions and note the officer's police station.
  • Call your insurance company's accident line, which usually works around the clock.
  • See a doctor if you feel any pain, even the next day, and keep the receipts.

Calling 119 and 110

Both lines start with a question that sorts the call. Answer with the key word, then the location. If you do not know the address, give a landmark, a shop name, a road number or a junction name, and stay on the line.

JapaneseRomajiMeaning
火事ですか、救急ですか。Kaji desu ka, kyūkyū desu ka.119: Is it a fire or an ambulance?
救急です。交通事故でけが人がいます。Kyūkyū desu. Kōtsū jiko de keganin ga imasu.You: Ambulance. A traffic accident with an injured person.
事件ですか、事故ですか。Jiken desu ka, jiko desu ka.110: Is it an incident or an accident?
事故です。車と自転車の事故です。Jiko desu. Kuruma to jitensha no jiko desu.You: An accident, between a car and a bicycle.
場所はどこですか。Basho wa doko desu ka.Operator: Where are you?
コンビニの前の交差点です。Konbini no mae no kōsaten desu.You: At the junction in front of a convenience store.
日本語があまり話せません。Nihongo ga amari hanasemasen.You: I don't speak much Japanese.

Exchanging details with the other party

Write down or photograph the other driver's licence and plate, and give your own details in return. If the other vehicle is a company car, note the company too. Collect a witness's name and phone number if someone saw what happened.

JapaneseRomajiMeaning
連絡先を交換しましょう。Renrakusaki o kōkan shimashō.Let's exchange contact details.
免許証を見せてもらえますか。Menkyoshō o misete moraemasu ka.May I see your driving licence?
保険会社はどこですか。Hoken gaisha wa doko desu ka.Which insurance company are you with?
ここで示談はできません。Koko de jidan wa dekimasen.I can't settle it here.
DetailJapanese wordWhy it matters
Name and addressShimei, jūshoFor the police report and the insurers
Phone numberDenwa bangōYour insurer will contact them
Plate numberNanbāIdentifies the vehicle
Insurance companyHoken gaishaThe insurers handle the claim between them
Vehicle owner or employerShoyūsha, kinmusakiThe driver may not be the owner

If the other party offers cash to keep the police out of it, decline politely. Jidan, a private settlement, should go through your insurer, and skipping the police report leaves you without the certificate you will need.

When the police arrive

The officers check everyone's ID and licences, ask what happened and examine the scene. If someone is injured, the case becomes an injury accident and the police carry out a more detailed on-site inspection, a jikkyō kenbun, which can take time. Answer in short sentences, say when you do not understand, and do not guess at speeds or distances you are not sure of.

A police officer with a notebook asks a cyclist and a driver what happened beside a junction, with hazard lights flashing.
Short, honest answers, and say so when you do not understand.
JapaneseRomajiMeaning
どういう状況でしたか。Dō iu jōkyō deshita ka.Officer: What happened?
青信号で渡っていました。Aoshingō de watatte imashita.You: I was crossing on a green light.
右から車が来ました。Migi kara kuruma ga kimashita.You: A car came from the right.
もう一度ゆっくりお願いします。Mō ichido yukkuri onegai shimasu.You: Once more, slowly, please.
人身事故jinshin jikoaccident with injury
物損事故busson jikoaccident with property damage only

Whether an accident is recorded as injury or property damage affects how it is handled. If you are injured and see a doctor later, the police can explain how to change the record, which usually needs a medical certificate, a shindansho.

Calling your insurance company

Your voluntary insurer's accident desk takes over most of the work: contacting the other party, assessing fault and paying claims. Have your policy number, the time and place, the other party's details and the police station ready. Many insurers offer English support; ask when you sign up.

JapaneseRomajiMeaning
事故の連絡をしたいです。Jiko no renraku o shitai desu.I'd like to report an accident.
証券番号はこちらです。Shōken bangō wa kochira desu.Here is my policy number.
警察にはもう届けました。Keisatsu ni wa mō todokemashita.I've already reported it to the police.
過失割合kashitsu wariaishare of fault (between the parties)

On a bicycle or on foot

JapaneseRomajiMeaning
自転車とぶつかりました。Jitensha to butsukarimashita.I collided with a bicycle.
今は痛くないけど、病院に行きます。Ima wa itakunai kedo, byōin ni ikimasu.It doesn't hurt now, but I'll go to hospital.
  • A bicycle is a vehicle under Japanese traffic law. A cyclist in an accident has the same duty to stop, help and report to the police as a driver.
  • Many prefectures and cities require cyclists to carry personal liability insurance. Check your local rule and whether your home or car insurance already includes cover.
  • As a pedestrian hit by a vehicle, insist that the police are called even if you feel fine, take the driver's details, and see a doctor the same day or the next. Some injuries show up later.
  • If a child is involved, call the police and the parents. Small collisions in parking areas and on pavements still count as accidents.

The days after: paperwork that follows

Once the scene is cleared, most of the work moves to your insurer. Keep a simple file with the date, place, police station, the officer's name if you have it, the other party's details, photos and every receipt. Your insurer will ask for these and may request the official accident certificate for you.

JapaneseRomajiMeaning
交通事故証明書kōtsū jiko shōmeishoofficial accident certificate
診断書shindanshomedical certificate
修理の見積もりshūri no mitsumorirepair estimate
  • The accident certificate, kōtsū jiko shōmeisho, is issued by the Japan Safe Driving Center based on the police report.
  • If you were injured, keep your medical certificate and receipts for treatment, medicine and transport to the clinic.
  • For repairs, the insurer usually wants an estimate from the garage before work starts.
  • If your car is off the road, ask whether your policy covers a loan or rental car.

Rehearse the calls before you ever need them

Accident calls are a good case for speaking practice, because you want the words without searching for them. Open AI Sensei on the travel emergency topic and ask Haru-sensei to play first the 119 operator, then a police officer at the scene. Practise giving a location from a landmark and describing what happened in three short sentences, and ask the Sensei to slow down when you need it. The session report shows which words you hesitated over.

To make the vocabulary stick, ask Mocchi to quiz you on jinshin jiko, busson jiko, jidan and kashitsu wariai, and to explain any you miss.

Key points

A practical way to improve

Prepare the calls while you are calm. Say the two openings aloud until they are automatic: jiko desu for 110 and kyūkyū desu for 119. Then practise describing a location three ways: an address, a landmark and a nearby shop or junction. Finally, rehearse the exchange of details, reading your own plate number and insurer's name aloud. Mocchi can quiz you on the accident words and correct a short description you write of what happened, which is exactly what the police and the insurer will ask you for.

FAQ

Frequently asked questions

Do I have to call the police after a minor accident in Japan?

Yes. Drivers involved in an accident, including cyclists, must report it to the police, even if it seems minor and no one is hurt. Without a police report, an official accident certificate cannot be issued later, and insurance claims become difficult.

What number do I call after an accident in Japan?

Call 110 for the police and 119 for an ambulance or fire. If someone is injured, call 119 first, then 110. Both lines answer in Japanese; many areas can connect interpretation, and simple key words like jiko and kyūkyū are understood immediately.

Should I apologise after an accident in Japan?

Asking whether someone is all right and saying sumimasen out of concern is normal and polite. What you should avoid is agreeing to who was at fault, signing anything or settling money on the spot. Leave fault and payment to the insurers.

What is a traffic accident certificate?

The kōtsū jiko shōmeisho is an official certificate that an accident was reported to the police. It is issued later by the Japan Safe Driving Center based on the police report, and insurers usually ask for it. Your insurer can often request it for you.
