- How to Identify a Hit-and-Run Driver from a Vehicle License Plate Number
- I want to consult about a traffic accident in the Yaizu, Makinohara, Yoshida, Omaezaki, or Fujieda area.
- I was a victim of a hit-and-run. Can I identify the driver from the vehicle's license plate number?
- I want to know if it is possible to trace the driver from a vehicle license plate number.
Are you experiencing concerns like these in Yaizu, Makinohara, Omaezaki, Fujieda, Shimada, Yoshida, or surrounding areas?
In cases of hit-and-runs or accidents where you were not given the other party's contact information, many people feel anxious, thinking, "I don't even know the other party's name or address... Can I still file a claim?"
In conclusion, if you have the license plate number information, there is a high likelihood that the at-fault driver can be identified through legal means such as a Bar Association Inquiry, so there is no need to give up.
At Yaizu General Law Office, we offer a free initial legal consultation regarding traffic accident concerns. There is no obligation to retain our services after an initial consultation. We are also available on weekday evenings and Saturdays. Please feel free to contact us by phone or email.
There Are Cases Where the At-Fault Driver Can Be Identified

If you are a victim of a hit-and-run in a traffic accident, or if you initially thought your injuries were minor but symptoms appeared later, you may want to file a damages claim against the at-fault driver but find that you do not know their name or address, or that you missed the opportunity to obtain their contact information.
In such cases, you might feel that there is nothing you can do because you have no information about the at-fault driver. However, if you remember the license plate number (vehicle registration number) of the at-fault driver's vehicle, it may be possible to determine the name and address of the at-fault driver (owner/registered user) from that information.
The methods for investigation differ between standard vehicles and light vehicles (kei cars), and each method is explained below.
Why Identifying the At-Fault Driver Is Important
- You will have to pay repair costs (property damage) out of pocket
- Medical expenses will be covered under health insurance, increasing your out-of-pocket costs
- Claims to the Compulsory Automobile Liability Insurance (CALI) cannot proceed if "at-fault driver information is insufficient"
- It may affect your application for residual disability certification
- Settlement negotiations become impossible
Even if you were unable to obtain the at-fault driver's contact information immediately after the accident, tracking is possible if you have the license plate number information.
In the Case of Standard Vehicles
For standard vehicles, you can obtain a "Certificate of Registered Vehicle Information" from the Land Transport Office. This can be obtained by anyone, not just the vehicle owner.
However, to obtain the Certificate of Registered Vehicle Information, you need to know not only the vehicle's license plate number (vehicle registration number) but also the chassis number (vehicle identification number).
As a result, since a traffic accident victim would have no way of knowing the chassis number, it is extremely difficult to obtain the Certificate of Registered Vehicle Information on your own.
If You Know Both the License Plate Number and Chassis Number, You Can Inquire at the Land Transport Office Yourself
Although uncommon in traffic accident cases, if you know not only the other vehicle's license plate number (vehicle registration number) but also the chassis number, it is possible for the victim to obtain the "Certificate of Registered Vehicle Information" at a Regional Transport Bureau or Vehicle Inspection and Registration Office.
The Certificate of Registered Vehicle Information contains information recorded in the vehicle registration file, including the names and addresses of the vehicle's owner and registered user.
The general procedure for making a request is as follows.
Confirm the license plate number and chassis number
As a general rule, the request requires:
- The vehicle registration number (license plate information)
- The last 7 digits of the chassis number
Both are required.
Even if you know only the license plate number, you generally cannot obtain the Certificate of Registered Vehicle Information.
Apply at a Regional Transport Bureau or Vehicle Inspection and Registration Office
Submit a completed application form for the Certificate of Registered Information to the nearest Regional Transport Bureau or Vehicle Inspection and Registration Office.
When making the request, in addition to the applicant's name and address, you must state a specific reason for needing the certificate, such as "for filing a damages claim against the other party in a traffic accident."
Submit identification documents
Present identification documents such as a driver's license and pay the prescribed fee.
If the request is approved, you can confirm the vehicle's owner, registered user, and other details through the Certificate of Registered Vehicle Information.
It Is Uncommon to Know the Chassis Number in Traffic Accident Cases
However, in actual traffic accidents, especially hit-and-run cases,
"The license plate number is captured on the dashcam, but the chassis number is unknown"
—this is the situation in most cases.
This is because the chassis number, unlike the license plate, is generally not visible from outside a moving vehicle.
Therefore, if you only know the license plate number of the other vehicle involved in the accident, it is usually difficult for the victim to obtain the owner's information from the Land Transport Office on their own.
Even in such cases, however, an attorney can obtain the Certificate of Registered Vehicle Information by making a Bar Association Inquiry to the Land Transport Office using only the vehicle's license plate number (vehicle registration number).
Key Points
- If both the license plate number and chassis number are known, the victim can request the Certificate of Registered Vehicle Information at a Regional Transport Bureau
- However, the chassis number is rarely visible from outside the vehicle, making it difficult for the victim to know
→In practice, it is virtually impossible for the victim to obtain information from the Land Transport Office on their own - Nevertheless, an attorney can conduct a "Bar Association Inquiry" using only the license plate number information
What Is a Bar Association Inquiry?
It is a system that allows an attorney, through their local bar association, to request information from public agencies.
Because this system is based on law, the Land Transport Office is, in principle, obligated to respond.
Through a Bar Association Inquiry, the following information can be obtained:
- Name of the vehicle owner
- Name of the registered user (if different from the owner)
- Address
- Chassis number
- Change history (e.g., when ownership was transferred)
Important Notes
- The registered user (the person who was actually driving) may differ from the owner
→Obtaining the registered user's information facilitates subsequent damages claims - Even in hit-and-run cases, the owner is not necessarily the at-fault driver, so additional investigation may be required
In the Case of Light Vehicles (Kei Cars)
Light vehicles are not registered at the Land Transport Office.
For light vehicles, the equivalent of the Certificate of Registered Vehicle Information for standard vehicles is the "Certificate of Inspection Record Information." The Certificate of Inspection Record Information can be obtained from the Light Motor Vehicle Inspection Organization; however, only the current owner may request it, so a traffic accident victim cannot obtain it.
However, just as with standard vehicles, if an attorney knows the vehicle's license plate number (vehicle registration number), the attorney can obtain the Certificate of Inspection Record Information through a Bar Association Inquiry.
Using Dashcam Footage and Security Cameras
When identifying the at-fault driver, dashcam footage often serves as the "decisive evidence."
From dashcam footage, the following can be determined:
- License plate number
- Vehicle make, color, and whether it has been modified
- Point of collision
- Direction of escape
If these details are clearly captured, both the police and an attorney can swiftly identify the at-fault driver.
In addition, security cameras at commercial facilities, convenience stores, or in front of the victim's home may also be useful.
Summary

As explained above, if you retain an attorney to handle your traffic accident damages claim, even if you have no information about the at-fault driver other than the vehicle's license plate number, it is possible to investigate and identify the at-fault driver through a Bar Association Inquiry.
If time passes while the at-fault driver remains unidentified after a hit-and-run, out-of-pocket expenses for medical and repair costs will increase, and applications for residual disability certification and settlement negotiations will become more difficult. Cases where you have only the license plate number information are precisely the situations where an attorney can make a significant difference.
At Yaizu General Law Office, the initial consultation for traffic accidents is free of charge. If you have any concerns, please do not hesitate to contact our office.
