The Challenge on Unfamiliar Roads

Renting a car in Japan offers freedom, but navigating unfamiliar roads comes with inherent risks. Being prepared for accidents is crucial for your safety and legal compliance.

Your Immediate Action Plan: 6 Critical Steps at the Accident Scene

In the chaotic moments after an accident, stay as calm as possible and follow these steps in order. Your structured response will make the entire process smoother and safer for everyone involved.

Emergency Response Steps

  • Step 1: Ensure Safety First

    Turn on hazard lights immediately. For minor accidents, move vehicles to roadside if safe. For significant collisions, do not move vehicles. Place reflective safety triangle behind your vehicle.

  • Step 2: Attend to the Injured

    Check yourself, passengers, and others. If anyone is injured, call 119 immediately. Say "Kega desu" (There is an injury) or "Kyukyusha onegaishimasu" (Ambulance, please).

  • Step 3: Report to the Police

    Must report every accident to police at 110, even minor scratches. Failure to report voids insurance and is illegal. Say "Jiko desu" (There has been an accident).

    Language Barrier Tip: Use translation app or ask for help. Say "Eigo, onegaishimasu" (English, please).
  • Step 4: Contact Your Rental Car Company

    Call the emergency number on dashboard sticker or rental agreement. They provide guidance in English, advise on vehicle status, and explain insurance claim process.

  • Step 5: Exchange Information

    Politely exchange: Name, Address, Phone Number, License Plate, Insurance Company and Policy Number.

    Crucial: Do NOT admit fault or offer private settlement (*jidan*). This can invalidate your insurance.
  • Step 6: Document Everything

    Use smartphone to photograph: wide-angle scene, vehicle damage, license plates, road conditions, traffic signs, skid marks, and witness contact information.

Key Terms and Concepts You Must Understand

Police Accident Certificate (交通事項証明書 - Kōtsū Jiko Shōmeisho)

The official document from police proving an accident occurred. Most important for insurance claims. You'll get a report number and instructions on how to apply for it later.

Collision Damage Waiver (CDW)

Basic insurance included with almost all Japanese car rentals. Covers rental vehicle/third-party property damage but usually has a deductible. Extra payment can waive this deductible.

Non-Operation Charge (NOC)

⚠️ Critical fee: Penalty paid to rental company for business lost while car is repaired. Applies regardless of fault. Standard CDW does NOT cover NOC. Requires optional insurance package to avoid.

The Role of Fault (過失割合 - Kashitsu Wariai)

Fault apportionment determined by insurance companies based on police report. Almost never 100-0. This is why you must NEVER admit fault at the scene.

Critical Takeaways

The Three Absolute Rules:

  • Always stop - Never leave the scene
  • Always call the police (110) - Even for minor scratches
  • Always call the rental company - They are your most important ally
