The police make an “On-the-spot Investigation Report” showing detailed information about the traffic accident. It is for the criminal record of the traffic accident. Since police make it as a third party, it will be one of the strong evidence on what exactly happened in the accident scene. Both a victim and an at-fault driver use the report for supporting their argument when their negotiation doesn’t go well.
The Certificate of Traffic Accident is a document proving the accident truly happened. It shows the detail of the accident, for example, the date and the place, the name of the people who were involved in and so on. The Japan Safe Driving Center issues the certificate based on some evidence and the documents submitted by the police.
The amount of compensation depends on the percentage of negligence in a traffic accident. If you're 30% faulty in the accident, the amount of compensation you legally deserve 30% decreases. The percentage of negligence is one of the biggest disputes between a victim and an at-fault party.
Give aid to the injured, call an emergency service, police, and insurance companies. If you have some extra time, collect information on the accident scene by taking pictures and recording the conversation with the police.
