Getting into a car accident is stressful anywhere, but in Japan, the rules and procedures can be overwhelming—especially if you’re a foreigner unfamiliar with the system. From language barriers to legal requirements, it’s crucial to know the right steps to take to avoid bigger troubles. Whether it’s a minor fender bender or a serious crash, this guide will walk you through everything you need to do.

What to Do After a Minor Accident
If it’s just a small bump with no injuries, follow these steps:
- Move to a Safe Spot
- Turn on your hazard lights.
- Move to the side of the road if possible.
- Call the Police (Dial 110)
- Reporting even minor accidents is legally required.
- If the other driver refuses to cooperate, the police ensure an official record.
- Exchange Information
- Get details from the other driver:
- Name, phone number, and address.
- Driver’s license number.
- License plate number.
- Insurance provider and policy number.
- If there are witnesses, get their contact information too!
- Get details from the other driver:
- Take Photos and Notes
- Capture the vehicle damage, accident location, and any important road signs.
- Note the date, time, and weather conditions.
- Inform Your Insurance or Rental Car Company
- Report the accident and follow their instructions.
- If you rented the car, notify the rental company immediately.

What to Do After a Serious Accident
Your safety comes first! According to Japan’s Road Traffic Act (Article 72), drivers involved in an accident must stop, assist the injured, and prevent further hazards.
- Move to a Safe Location
- On highways, use hazard lights and pull over to a safe shoulder.
- On regular roads, move as far away from traffic as possible.
- Call the Police (Dial 110)
- Reporting is mandatory—even for minor incidents.
- If you skip this step, you may have trouble claiming insurance later.
- Check for Injuries and Call an Ambulance (Dial 119)
- If anyone is hurt, call emergency services immediately.
- Larger cities have language assistance for emergency calls.
- Provide first aid while waiting for help:
- Check if the person is conscious.
- Assess breathing.
- Perform CPR if necessary.
- Contact Your Insurance or Rental Car Company
- Insurance companies handle accident negotiations, so don’t settle privately.
- If you’re at fault, still collect the other party’s details and take photos.
