Japan Car Rental Insurance Explained | What's Included, CDW vs NOC, and When Cover May Not Apply

Japan Car Rental Insurance Explained | What's Included, CDW vs NOC, and When Cover May Not Apply

Before you take the key, know what your rental rate already covers (illustrative image)

At a Japanese rental counter you will hear words like menseki hosho (CDW), NOC and anshin pack, usually in quick Japanese, right before you sign. Many travellers nod along, scrape a bollard on day two and still receive a bill for tens of thousands of yen. GoodCars breaks Japanese rental car insurance into plain layers: what the base rate already includes, what the deductible is, what a collision damage waiver actually removes, why the NOC is a separate charge, which situations the terms list as excluded, and what to do at the scene so you do not lose cover through a missed step.

The amounts below are published rates on the websites of major Japanese rental companies, used as a market reference. The systems are broadly similar but the details differ, so the terms of the company you actually book always prevail. For the full cost picture, see our Japan car rental price guide.

What the base rental rate usually includes

In Japan, the base rental rate normally comes with motor insurance and compensation already built in, so you generally do not need to buy anything extra just to drive away, though what is included is shown on your booking page. Based on what major companies publish, the four standard elements look like this:

Sample published rates: insurance and coverage pages of ORIX Rent-A-Car (car.orix.co.jp/userguide/insurance.html), Toyota Rent a Car (rent.toyota.co.jp/static/service/insurance/index.html) and Nippon Rent-A-Car (nipponrentacar.co.jp/guide/userguide.html), checked on 13 November 2026, tax included. Terms differ by company; the terms of the company you book and your booking page always prevail.

Third-party cover is about damage you cause to others (illustrative image)

The column that matters is the deductible. Base cover is not "full cover": when you damage property or the car, you pay the first slice yourself, and anything above the limits is also yours. GoodCars note: when you search on /global/, the car list shows "basic insurance included", but each supplier's cover, deductible and whether any optional protection is offered can differ, so always check the booking page.

What is the deductible, and what does CDW remove?

The deductible (menseki-gaku) is the amount you pay first when something happens. For a standard car the published coverage guides commonly set ¥50,000 for property damage and ¥50,000 for vehicle damage, so one scrape that hits someone else's property and damages your rental car can mean ¥100,000 out of pocket.

The collision damage waiver (menseki hosho seido, CDW) is a small daily fee that waives that deductible. Major companies publish ¥1,100 per 24 hours or per day for compact classes and about ¥2,200 for larger classes. Common rules:

• It is optional, not mandatory.
• It usually has to be added at pick-up; you cannot add or cancel it mid-rental (based on published coverage guides).
• It waives only the property and vehicle deductibles. It does not cover the NOC or anything above the cover limits.
• Some companies state that if several accidents happen in one rental, it applies only to the first.

CDW is often misread as "fully covered", but there is still the NOC below to look at separately.

NOC (non-operation charge): a fee usually still payable with CDW

The NOC is not a repair bill. It is part of the income the rental company loses while the car is off the road for repair or cleaning, and the renter pays it. Accidents, breakdowns, theft and heavy soiling can all trigger it. The amounts in published coverage guides are remarkably consistent:

Several companies state that the NOC applies even if you bought CDW; whether and how much your supplier charges is set by its own terms and booking page. When the car cannot be driven, some companies cover towing to their designated workshop only up to ¥150,000, with anything above that charged to you.

If the car cannot be driven back, the NOC is commonly ¥50,000 (illustrative image)

NOC waivers and daily cost: sample published rates

To remove the NOC too, you add an NOC waiver. Names vary: "Anshin Pack", "Anshin Plan", "NOC cover". Some are bundled with CDW, and some also cover tyre repair, roadside help or a short grace period on late return; public pages mostly do not say whether the NOC waiver can be bought on its own. Sample published rates from major companies (compact class, per 24 hours or per day, tax included):

Even with these plans, some cases are not waived. Examples listed on the companies' pages: an NOC caused by interior soiling or odours, theft, or acts that breach the rental terms is not waived; if several accidents happen in one rental, only the first is covered; tyre cover has a cap. Details differ by company, so the terms of the company you book prevail.

Sample published rates: same three company pages as above, checked on 13 November 2026, tax included. The terms of the company you book and your booking page always prevail.

A rough estimate from the rates above: three days with both layers is roughly ¥4,600–5,300 (our own estimate, not a quote from any company). Without them, one minor accident where the car is still drivable can mean a ¥50,000+ deductible plus a ¥20,000 NOC. Whether it is worth it is your call; GoodCars simply suggests putting those two numbers side by side. When you book through GoodCars, whether a supplier offers an NOC waiver and what it costs is shown on the booking page; this article does not assume anything on any supplier's behalf.

When cover may not apply: common exclusions in published coverage guides

This is the section to read twice. Even with CDW and an NOC waiver, if a situation falls under the exclusions, both the base insurance and the optional waivers may not apply and you may have to pay the loss yourself; the terms of the company you book decide. Common items in the published coverage guides of major companies (wording and scope vary):

Procedures not followed

• Not reporting the accident to the police or not contacting the rental company (no police report means no accident certificate)
• Hit-and-run damage or theft from the car also has to be reported to the police
• Settling privately with the other party without the company's consent

Breaches of the rental agreement

• Driving under the influence of alcohol or drugs
• Driving by anyone not registered on the contract, or lending the car to someone else
• Driving without a valid licence. Whether you can drive in Japan depends on where your licence was issued. Licences from countries party to the 1949 Geneva Convention need an International Driving Permit in that format, plus the original licence and passport. Licences from Switzerland, Germany, France, Belgium, Monaco and Taiwan need an official Japanese translation instead of an IDP. Licences from some countries (for example mainland China and Indonesia) cannot be used in Japan even with an IDP. Check with your licensing authority and the rental company before you book; without the right documents the rental company may refuse to hand over the car, and you may be treated as an unlicensed driver
• Extending the rental without telling the company
• Damage caused by illegal parking

Often listed as outside cover, or at your own cost

• Lost or damaged keys; theft after leaving the key inside or the car unlocked
• Punctures and lost wheel caps: often outside base cover unless your add-on includes tyres
• Damage from filling the wrong fuel
• Damage from driving off-road, such as on beaches, riverbeds or forest tracks
• Interior soiling or odours (for example smoking in a non-smoking car) and lost equipment
• Recovery after getting stuck in snow or mud, which some roadside services exclude
• Damage from earthquakes, volcanic eruptions and resulting tsunamis

Exclusions summarised from the insurance and coverage pages of ORIX Rent-A-Car, Toyota Rent a Car and Nippon Rent-A-Car (same pages, checked the same day). Wording and scope differ by company; the terms of the company you book prevail.

At the scene: steps you must not skip

The very first exclusion above is "no police report". If you do not call the police and the rental company, cover usually does not apply; the steps below are the basic conditions, but whether cover applies is still decided by the rental company and insurer under their terms. For the full step-by-step guide and phone numbers, see what to do after an accident, puncture or breakdown in Japan. The insurance-related essentials:

1. Safety first: hazard lights on, move to a safe spot, call 119 if anyone is hurt.
2. Always call the police (110), even for a solo scrape with no other party. Only a police-registered accident gets a certificate.
3. Call the rental company immediately using the emergency number on your contract or in the car.
4. Do not agree to pay or settle on the spot; leave it to the rental company and insurer.
5. Take photos and note the police station handling the case, the other party's details, time and place.

For traffic rules and penalties, see Japan traffic rules and fines. GoodCars tip: photograph the emergency number at pick-up and walk around the car with staff, photographing existing scratches, so you are not scrambling later.

Can a credit card or travel insurance replace it?

Many travellers ask whether the rental cover on their credit card or their travel insurance means they can skip the Japanese company's waivers. There is no one-size answer. GoodCars can only offer general pointers; your card and policy terms decide:

• Scope: does it cover Japan and the vehicle class, and do you have to pay the rental with that card?
• What it pays: damage to the rental car, or also third-party liability? Does it include contractual charges such as the deductible and the NOC?
• How claims work: this varies by card; commonly you pay first and claim later with documents such as the accident certificate and repair invoice, so ask what is needed.
• Travel insurance mainly covers you and your medical costs; liability for damage caused while driving is excluded by some policies.

Credit card rental cover varies by card (illustrative image)

The safest approach is to call your card issuer or insurer before you travel, ask those four questions and get the answer in writing. Until you have, do not assume it replaces the rental company's cover.

How to choose: five checks before you go

1. Check the base cover: property damage limit and deductible.
2. Decide on CDW: multiply the daily price by your rental days and compare it with a ¥50,000+ deductible.
3. Look at the NOC waiver: is there one, what does it cost, does it include tyres and roadside help?
4. Read the exclusions once: anyone who will share the driving must be registered at booking.
5. Photograph the car at pick-up: all sides, tyres, fuel gauge and mileage.

If it is your first time driving on the left, your route includes mountains or snow, or the rental is long, the risk is usually higher; if the company you book offers CDW and an NOC waiver, they are worth considering. In the end it is your call based on your budget and risk tolerance.

FAQ

Q1. Does a Japanese rental car include insurance?

Usually yes. The base rate normally includes third-party injury, third-party property, vehicle damage and occupant injury cover, but property and vehicle damage carry deductibles, commonly ¥50,000 each in published coverage guides. When booking through GoodCars, the booking page shows the actual cover.

Q2. Do I have to buy CDW?

No, it is optional. The published compact-class rate is around ¥1,100 per day and it waives the property and vehicle deductibles. Based on published coverage guides, it usually has to be added at pick-up and cannot be added mid-rental.

Q3. If I buy CDW, do I still pay the NOC?

In the published coverage guides we checked, generally yes: the NOC is separate, commonly ¥20,000 if the car can be driven back and ¥50,000 if not, and removing it requires an NOC waiver. Whether and how much your supplier charges is set by its own terms and booking page.

Q4. Can I buy the NOC waiver without CDW?

Public pages mostly do not say whether the NOC waiver can be bought on its own, and some companies sell it only as a bundle with CDW. Check the terms of the company you book and your booking page.

Q5. Is a puncture or tyre damage covered?

Published coverage guides commonly exclude tyres and wheel caps from base cover, so repair is at your cost unless your add-on includes tyres. For what to do at the roadside, see our accident and puncture guide.

Q6. My credit card includes rental car cover. Can I skip the rental company's waivers?

Check the card terms: whether Japan is covered, what is paid, whether deductibles and the NOC are included, and how to claim. GoodCars recommends confirming with your card issuer first and not assuming it is a replacement.

Q7. Where can I see the insurance details when booking with GoodCars?

The /global/ car list shows "basic insurance included". The deductible, whether a supplier offers CDW or an NOC waiver, and at what price, differ by supplier and are not confirmed by this article. Rely only on what the booking flow actually shows; do not assume an item exists if it is not listed. Contact GoodCars support before you book if unsure.
