Quick Answer
Foreign visitors renting a car in Japan should choose insurance and coverage options that they clearly understand.
At a minimum, you should check what is included in the basic rental plan, what deductible may apply, whether CDW is available, and whether NOC is covered or not.
Do not assume that “insurance included” means every cost is fully covered.
When renting a car in Japan, insurance is one of the most important things foreign visitors should understand before booking.
The problem is that rental car insurance terms can be confusing, especially if you are reading them in a second language or comparing several companies at once.
Many travelers see words like basic insurance, CDW, deductible, excess, compensation, and NOC, but they are not always sure what each one means.
This guide explains the basic points foreign visitors should check before choosing insurance or coverage options for a rental car in Japan.
Why rental car insurance matters in Japan
Driving in a foreign country always involves some risk.
Even if you drive carefully, you may face unfamiliar roads, narrow streets, toll roads, parking systems, different traffic signs, or unexpected weather.
Insurance and coverage options matter because they affect what you may need to pay if something goes wrong.
The goal is not to choose the cheapest option. The goal is to understand your financial risk before you drive.
What is usually included in a basic rental plan?
Many rental cars in Japan include some form of basic insurance or mandatory coverage.
This may include coverage related to bodily injury, property damage, vehicle damage, or personal injury, depending on the rental company and plan.
However, the details can vary.
You should check:
- what types of damage or accidents are covered
- whether there is a deductible or excess
- whether NOC is included or excluded
- whether tires, wheels, glass, keys, or undercarriage damage are covered
- whether roadside assistance is included
- what steps you must follow after an accident
Basic coverage does not always mean zero out-of-pocket cost.
What is a deductible or excess?
A deductible, sometimes called an excess, is the amount you may need to pay yourself before coverage applies or when certain damage occurs.
For example, if the rental agreement includes a deductible for vehicle damage, you may still need to pay up to that amount even if the car is insured.
The exact amount depends on the rental company, vehicle class, and coverage option.
This is why you should read the rental conditions before booking.
What is CDW?
CDW usually means Collision Damage Waiver.
It is an optional product that may reduce or waive the amount you need to pay for certain vehicle damage.
However, CDW is not always the same across all rental companies.
Some CDW options may reduce the deductible, while others may not cover every type of damage.
Before adding CDW, check exactly what it covers and what it excludes.
What is NOC?
NOC stands for Non-Operation Charge.
In Japan, NOC may apply if the rental car cannot be used by the rental company because of an accident, damage, breakdown, or other issue during your rental.
This charge is separate from ordinary repair costs or insurance in many cases.
For example, even if damage itself is covered, you may still be charged NOC if the rental company loses the ability to rent out the vehicle while it is being repaired.
NOC is one of the most important charges foreign visitors should check before renting a car in Japan.
Is NOC always covered?
No. NOC is not always covered by basic insurance.
Some rental companies may offer an optional plan that covers or reduces NOC. Others may not include it unless you choose an additional package.
This is why you should not only ask, “Is insurance included?”
You should also ask:
- Is there a deductible?
- Is NOC included?
- Can NOC be waived with an optional plan?
- What happens if the car cannot be driven after an accident?
If you do not understand NOC, ask the rental company before you drive away.
Ready to compare rental companies?
Insurance options, deductibles, NOC rules, ETC card availability, and return procedures can vary depending on the rental company.
Before booking, it is useful to compare rental companies not only by price, but also by how clearly they explain insurance and support.
Best Car Rental Companies in Japan for Foreign Drivers
What should foreign visitors check before booking?
Before you reserve a rental car, check the insurance and coverage details carefully.
Important points include:
- what basic insurance is included
- whether a deductible or excess applies
- whether CDW is available
- whether NOC is covered
- whether tires, wheels, glass, keys, and undercarriage are covered
- whether roadside assistance is included
- what to do after an accident or breakdown
Always read the rental conditions before confirming your booking.
What about coverage from a comparison platform?
If you book through an online comparison platform, you may see additional coverage options offered by that platform.
These options may be separate from the rental company’s own insurance or waiver products.
This means you should understand who provides the coverage, what it covers, how claims work, and whether you still need to pay the rental company first and request reimbursement later.
Do not confuse rental company insurance with third-party or platform coverage. They may work differently.
What documents should you keep?
If an accident, damage, or claim happens, records matter.
You should keep documents such as:
- rental agreement
- booking confirmation or voucher
- damage report
- police report if applicable
- receipts and invoices
- photos of the car before and after rental
- emails or messages from the rental company
Good records can help if you need to explain what happened or request compensation.

Take photos before driving
Before leaving the rental location, check the car carefully.
If possible, take photos of the car from multiple angles, including existing scratches, dents, wheels, bumpers, mirrors, and windshield.
This is especially useful if there is a later question about whether damage was already present at pickup.
Take photos before you drive and keep them until the rental return is fully completed.
Should you choose extra coverage?
There is no single answer for every traveler.
Extra coverage may be worth considering if:
- you are not used to driving in Japan
- you will drive long distances
- you will use expressways often
- you are driving in rural or mountain areas
- you want to reduce financial uncertainty
- you are traveling with family and want less stress
However, extra coverage is not automatically necessary for everyone.
The best decision depends on your route, driving confidence, budget, and risk tolerance.
Common insurance mistakes foreign visitors should avoid
Foreign visitors should avoid these common mistakes:
- assuming basic insurance covers everything
- not checking the deductible or excess
- forgetting about NOC
- not understanding the difference between CDW and full coverage-style products
- not reading exclusions
- not keeping photos or receipts
- not contacting the police or rental company after an accident
- choosing only by price without checking coverage details
The biggest mistake is booking without understanding what you may still have to pay after trouble happens.
So, what insurance should foreign visitors choose?
The safest practical answer is this:
Choose the insurance or coverage option that you clearly understand and that matches your trip risk.
For many foreign visitors, it is worth considering additional coverage if they are unfamiliar with Japanese roads or want to reduce uncertainty.
But whatever you choose, make sure you understand:
- what is included
- what is excluded
- what deductible applies
- whether NOC is covered
- what procedure you must follow after an accident
Do not choose insurance by name alone. Choose it by what it actually covers.
