The Ultimate Guide to Driving in Japan: International Driving Permits, Renting and Picking Up a Car, Traffic Rules, and Procedures for Accidents and Returns

The most common issues when driving in Japan aren't caused by right-hand drive vehicles, but by invalid documentation, misinterpreting "Stop" (止まれ) signs, ignoring pedestrian priority, or failing to call the police after minor collisions. Even if a car rental company provides an interface in your language, it does not mean drivers can skip Japan's traffic rules.

Five Core Principles for Safe Driving: Ensure your license documents are valid; photograph the vehicle's condition when picking it up; come to a complete stop at "Stop" signs; actively yield at pedestrian crossings; and in any accident, prioritize safety first, then contact the police and the rental company.

License requirements, penalties, insurance, roads, and rental terms are subject to change and may vary depending on the jurisdiction where your license was issued. This article provides general travel information and does not constitute legal or insurance advice; you should confirm details with the National Police Agency of Japan, your license-issuing authority, the rental company, and your insurance provider before departing.

What documents are needed to drive in Japan?

An International Driving Permit (IDP) is not globally universal

Japan accepts IDPs issued by authorized agencies that follow the format of the 1949 Geneva Convention on Road Traffic. "International driving cards" bought online, translation cards, or documents that do not meet the convention's format cannot replace official documents.

Which travelers need a Japanese translation?

Travelers with licenses from certain countries or regions may need to carry their original license along with a Japanese translation produced by an authorized Japanese body, rather than an IDP. Please check the latest official Japanese regulations for the applicable list and translation agencies.

How should Chinese-speaking travelers determine what they need?

• Do not look at your passport nationality; check the jurisdiction that issued your license.
• Confirm the convention version accepted by your license-issuing authority.
• Send photos of your documents to the rental company for pre-approval, but still carry the originals.
• Requirements vary greatly by region; do not rely solely on a friend's experience.

How long is an IDP valid?

Driving eligibility in Japan involves the IDP’s own expiration date, your entry date, and Japanese regulatory limits; do not rely solely on the date printed on the card. Short-term re-entry after departing does not necessarily reset the period; long-term residents should be especially careful to verify.

What if I entered via an automated gate and have no entry stamp?

Some rental companies may need to verify your entry date. When using an automated gate, you can request an entry record stamp from airport staff, or ask the rental company in advance which documents they accept as proof.

8 things to confirm before booking your rental

1. Register all potential drivers.
2. Ensure the car model can accommodate all passengers and luggage.
3. Determine if you need child safety seats.
4. Check if winter tires are included during snow season.
5. Consider if an ETC card and highway pass are needed.
6. Verify if basic accident damage coverage and NOC are included.
7. Check for one-way rental fees.
8. Note business hours, late pick-up policies, and cancellation terms.

What is the difference between Damage Waiver and NOC?

A Damage Waiver (CDW) typically reduces or waives the deductible for vehicle damage or third-party property accidents. NOC (Non-Operation Charge) is a fee charged by the rental company for loss of business while the vehicle is being repaired, cleaned, or replaced due to an accident, damage, or other issues.

Buying a Damage Waiver does not automatically cover NOC. Some all-inclusive plans cover both, while others require them to be added separately.

What might "Full Coverage" still exclude?

• Driving by an unregistered driver.
• Driving under the influence, drugs, or reckless driving.
• Failure to report an accident to the police or the rental company.
• Violation of rental terms or driving on prohibited roads.
• Specific items like tires, rims, undercarriage, keys, and interior staining.
• Mis-fueling.
• Loss of personal items or property.

Coverage names can be similar, but actual exclusions may vary significantly. Read the insurance summary and rental agreement before paying.

Five vehicle checks at pick-up

1. Vehicle model and luggage space

Small Japanese cars may not fit multiple large suitcases. Do not just look at "seats 5"; check how much luggage you can fit when the car is full.

2. Seats, child seats, and equipment

Ensure child seats are securely installed. Adjust seats, mirrors, and the steering wheel. Familiarize yourself with wipers, lights, the parking brake, gear shift, fuel cap release, and GPS.

3. Vehicle damage

Walk around the car and photograph the front, back, sides, rims, windows, roof, bumpers, and interior. Write any existing scratches on the vehicle condition report and keep the photos until your deposit is settled.

4. Fuel type

Confirm the fuel type, the amount of fuel at pick-up, and return requirements. In Japan, these are typically "Regular," "High-Octane," and "Diesel" (軽油). Note: "Light vehicle" (軽自動車) does not mean it uses diesel.

5. ETC card and emergency documents

Verify that the ETC card is correctly inserted. Note the rental company’s roadside assistance number, accident procedures, and the location of the vehicle registration documents. ETC rental fees and toll charges may be billed separately.

Basic rules for driving in Japan

• Drive on the left side of the road; the driver's seat is usually on the right.
• Turning right requires crossing oncoming traffic; exercise extra caution.
• Be careful of bicycles and pedestrians when turning left.
• Wiper and turn signal positions may be the opposite of your home vehicle; practice before leaving.
• Stay on the left even when turning into small roads; do not drift toward the center due to narrow lanes.

Four common traffic violations

1. "Stop" (止まれ): A complete stop is mandatory

The red inverted triangle "Stop" sign means you must come to a complete stop before the stop line, check that it is safe to proceed, and then move forward. Merely slowing down does not count as a stop.

The fines and demerit points listed (approximately 7,000 yen for regular cars) are examples; actual penalties vary based on regulations and updates.

2. Railway crossings: Stop, look, and confirm

When approaching a railway crossing, you should generally stop, ensure no train is coming, and confirm there is enough space on the other side before crossing. Follow traffic rules for signal-controlled crossings.

Do not stop inside the barrier zone, and do not follow the car in front if the exit is jammed. The penalty listed (approx. 9,000 yen) is for reference only.

3. Pedestrian crossings: Yield to pedestrians

When approaching an unsignalized pedestrian crossing, if a pedestrian is crossing or clearly preparing to cross, drivers must slow down and stop to yield.

Diamond road markings usually indicate a pedestrian or bicycle crossing ahead. They are not decorative; when you see these, you should actively scan both sides of the road.

4. Time restrictions and no-entry zones

Residential areas, school zones, and shopping streets often have signs prohibiting general traffic at specific times. The "7-9" or "17-19" below the sign indicates the restricted hours, not a speed limit.

Even if the GPS directs you to enter, prioritize road signs. Exceptions for residents, buses, taxis, or specific vehicle types do not apply to rental cars.

Other commonly overlooked rules

Speed limits

Follow circular speed signs and local regulations. Limits in narrow residential areas, mountain roads, and near schools may be very low. Do not just follow the speed of the car in front.

Mobile phones

Using a handheld phone, entering GPS coordinates, or reading messages while driving is dangerous and potentially illegal. Set your route before leaving; if you need to operate a device, pull over in a legal, safe spot.

Seatbelts

Passengers in both front and back seats must wear seatbelts. Children must use seats appropriate for their age and size.

Drunk driving

Japan has strict penalties for drunk driving. Providing alcohol, being a passenger, or knowingly allowing an intoxicated person to drive can also result in liability. Heavy drinking the night before can still lead to exceeding the legal limit the next morning.

No turning left on red

Generally, you cannot turn left on a red light in Japan unless a specific arrow or sign explicitly permits it.

Parking rules: Just because you don't see a police officer doesn't mean it's allowed

On-street parking in urban areas is strictly regulated. Illegal parking may result in a fine, towing, or complications with your rental return. Do not park in/near:

• Pedestrian crossings or near intersections.
• In front of fire hydrants, garages, or emergency exits.
• Bus stops, taxi zones, or bicycle lanes.
• Narrow roads without marked parking spaces.
• Convenience store lots if you aren't a customer or if you leave your car for a long time.
• Private property or reserved parking spots.

How to use coin parking

Common types include gate-style, wheel-lock plates, or license plate recognition. Before leaving, go to the payment machine, enter your space number or license plate, verify the amount, and pay. Do not attempt to drive away before the lock plate is fully lowered.

"Maximum fee" does not always mean a flat daily rate

The maximum fee may apply only once, for a specific time window, or for 24 hours after entry, and it may reset at midnight. Look closely for terms like "繰り返し適用" (repeated application) or "当日限り" (valid for the current day only).

Highways and ETC

ETC allows for automated highway toll payment but requires an on-board unit and a valid ETC card. If the rental company provides a card, they usually settle the actual toll charges upon return.

Entering the ETC lane

• Confirm the on-board unit shows the card is valid.
• Enter at low speed according to the limit, and keep distance from the car in front.
• If the barrier doesn't open, stop immediately; do not reverse.
• Follow staff instructions if you enter the wrong lane.

Can I use highways without an ETC card?

Most sections still offer manual payment, but some entrances are ETC-only. Plan your route in advance to avoid needing to switch lanes at the entrance.

How to use gas stations

Self-service refueling

1. Turn off the engine; smoking and open flames are prohibited.
2. Choose the correct fuel type.
3. Select payment method and fuel amount, or choose "full."
4. Touch the static electricity removal plate.
5. Open the fuel cap and insert the nozzle.
6. Replace the cap after refueling and collect your receipt.

Useful Japanese phrases

• レギュラー満タンでお願いします。
  Please fill it up with regular gasoline.
• この車は何の燃料ですか？
  What kind of fuel does this car take?

Never guess if you are unsure. Misfueling can cause serious damage and is usually not covered by standard insurance.

What if an accident occurs?

Report it to the police, even for minor scratches. Without a police report or accident certificate, insurance and rental compensation may not be applicable.

Accident handling steps

1. Stop safely and turn on hazard lights.
2. If someone is injured, call 119 immediately and provide necessary aid.
3. Call 110 to report the traffic accident.
4. Do not leave the scene.
5. Exchange names, phone numbers, license plate numbers, and insurance information with the other party.
6. While safe to do so, photograph the vehicles, road, signals, and damage.
7. Notify the rental company and the insurance assistance center immediately.
8. Follow instructions to obtain the accident report and relevant documents.

Can I settle privately?

It is not recommended to settle with cash alone. Damages or injuries may be discovered later, and rental companies/insurers typically require a police report.

What if I don't speak Japanese?

Say "Koutsu jiko desu" (交通事故です - "It is a traffic accident") and provide your location. You can ask the rental company to translate or use a translation service, but do not skip reporting to the police due to a language barrier.

What if the car breaks down?

• Move to a safe position and turn on hazard lights.
• If on a highway, get out of the vehicle and stand behind the guardrail.
• Place a warning triangle and follow the rental company's instructions.
• Contact roadside assistance and the rental company.
• Do not attempt repairs, tow the vehicle yourself, or keep driving a car with warning lights on.

Highway emergency numbers, roadside assistance, and rental company support are different. Save these numbers in your phone when you pick up the car; don't wait for a breakdown to look for the documentation.

Driving in snow and winter

Regions like Hokkaido, Tohoku, Hokuriku, Nagano, and mountainous areas may require winter tires, snow chains, or road restrictions. Four-wheel drive does not replace the need for proper tires and winter driving skills.

• Increase following distance.
• Avoid sudden braking, turning, or acceleration.
• Bridges, tunnel entrances, and shaded areas are prone to black ice.
• Do not pour hot water directly on frozen windshields.
• Cancel unnecessary trips during blizzard warnings.
• Verify if your rental agreement allows travel into snowy mountainous areas.

Mountain roads and animal risks

In Hokkaido, you may encounter deer; mountain areas may have monkeys, wild boars, and other animals. Reduce speed at dusk and at night, and avoid sudden swerving into the opposing lane.

If you hit an animal, pull over safely, call the police, and notify the rental company. Do not approach an injured wild animal.

Four steps for returning the car

1. Fill up at a designated gas station

Some companies require you to refuel within a certain distance from the shop and show a receipt. If you chose a prepaid fuel option, follow your contract.

2. Arrive early

Allow time for traffic, refueling, vehicle inspection, and transfers. If returning at an airport, allow extra time for the shuttle to the terminal.

3. Remove ETC card and personal items

Check the glove box, under seats, charging ports, the trunk, and child seats. If you rented an ETC card, return it according to branch policy; do not take it home by mistake.

4. Keep settlement documents

Retain the final agreement, condition record, gas receipt, ETC charges, and deposit settlement until your credit card statement is verified.

Pre-departure checklist for international travelers

• Bring originals of your passport, domestic license, and IDP or Japanese translation.
• Include all drivers in the rental contract.
• Download offline maps and save addresses in Japanese.
• Confirm your phone mount and charging equipment.
• Purchase appropriate Damage Waiver and NOC coverage.
• Check weather, road closures, and winter equipment requirements.
• Allocate time for refueling and returning the vehicle.

Frequently Asked Questions (FAQ)

Can I just bring an IDP to rent a car in Japan?

Usually, you must also carry your passport and the original domestic driver's license. Required combinations depend on your license jurisdiction.

Are all IDPs valid in Japan?

No. Japan primarily accepts valid IDPs that follow the 1949 Geneva Convention format; some licenses require a recognized Japanese translation instead.

Can a new driver rent a car in Japan?

You must meet both legal requirements and the rental company’s conditions. Some companies may set restrictions based on age, years of driving experience, or vehicle type.

Is it okay to just slow down and roll through a "Stop" sign?

No. You must come to a complete stop before the stop line, check that it is safe, and then proceed.

Can I turn left on a red light in Japan?

Generally no, unless specifically permitted by an arrow signal or sign.

Do I need to call the police for minor scratches?

Yes. Police records are essential for rental and insurance processing, and you should notify the rental company immediately.

Does CDW mean I don't have to pay the NOC?

Not necessarily. Damage Waivers and Non-Operation Charges are separate items; check your specific plan.

Do compact cars use diesel?

Not necessarily. Most light passenger cars use regular gasoline. "Light" (軽) refers to the vehicle tax category, not fuel type.

Conclusion: Driving on the left is just the start; stopping correctly is true safety

The real test of driving in Japan isn't handling a right-hand drive car, but the ability to come to a full stop at "Stop" signs, yield early to pedestrians, and follow proper procedures even after a minor accident.

Prepare your documents fully, photograph the car at pick-up, understand your coverage, and save your return receipts. Mastering these basics gives you the peace of mind to enjoy the roads of Hokkaido, the lakes of Mt. Fuji, and the Japanese countryside.
