Renting a car and driving through Japan opens up experiences that trains and buses simply cannot reach — a mountain onsen village accessible only by a winding forest road, a coastal fishing town between two peninsulas, or the quiet countryside of Tohoku between rice fields and cedar-lined shrines. Japan's road network is excellent and the country is considerably safer to drive in than most people expect. But it does require preparation.
Japan drives on the left side of the road, uses a different license system than most Western countries, and has some traffic rules that are easy to misunderstand. This guide covers everything you need to know before you get behind the wheel.
1. Do You Need an International Driving Permit?
Whether you need an International Driving Permit (IDP) depends entirely on which country issued your license. Japan is not a signatory to the 1949 Geneva Convention for all countries, which means a standard IDP from some nations is not sufficient. The rules are strict and Japan's police enforce them.
Citizens of countries that signed the 1949 Geneva Convention can drive with a valid IDP alongside their home country license. This includes most of Europe, Australia, New Zealand, Canada, South Africa, and many others. The IDP must be obtained before arriving in Japan — you cannot get one in Japan.
Americans can drive in Japan with an IDP issued under the 1949 Geneva Convention. AAA and AATA issue these in the US. The 1968 Vienna Convention IDP is not valid in Japan. Always verify which convention your IDP falls under before traveling.
Drivers from China and South Korea (and some other countries) cannot use an IDP in Japan at all. They must obtain an official Japanese translation of their license from the Japan Automobile Federation (JAF) or their country's embassy before driving.
Driving in Japan with an invalid or insufficient permit is a criminal offense, not just a traffic violation. You can be arrested, your rental insurance will be void, and you will be personally liable for any accidents. Always verify your documentation before renting.
2. Key Road Rules Every Foreign Driver Must Know
Japan's traffic laws overlap significantly with other countries, but there are several rules that catch foreign drivers off guard. Understanding them before you start driving will save you from expensive fines and dangerous situations.
Drive on the Left
This is the most fundamental difference. Japan drives on the left, which means the steering wheel is on the right side of the car. If you have never driven on the left, spend time in an empty parking lot before entering traffic. The most common mistake new left-side drivers make is drifting toward the center line when turning.
Speed Limits
Japan's speed limits are lower than those in Europe and North America. The standard limits are:
| Road Type | Speed Limit |
|---|---|
| Expressway (高速道路) | 100 km/h (some sections 110–120 km/h) |
| National highway (国道) | 60 km/h |
| Urban road (市街地) | 40–60 km/h |
| Residential / school zone | 30 km/h |
Speed cameras are very common in Japan, and fines are substantial. Police also conduct manual speed checks on national highways. Stick close to the limit.
Alcohol and Driving
Japan has one of the strictest drink-driving laws in the world. The legal blood alcohol limit is 0.03% BAC — roughly one drink for an average-sized adult. In practice, Japanese driving culture treats any alcohol before driving as unacceptable. Passengers who knowingly allow a drunk person to drive them can also be fined. If you plan to drink, arrange a designated driver or use a taxi.
Mobile Phones
Using a mobile phone while driving — including holding it to your ear or looking at the screen — is illegal and carries heavy penalties including license suspension. Hands-free Bluetooth is permitted. Mount your phone in a holder before you start driving.
3. Expressways and Toll Roads
Japan's expressway network (高速道路, kōsoku dōro) is extensive, well-maintained, and the fastest way to cover long distances. However, all expressways in Japan are toll roads. Costs add up quickly on long-distance drives.
ETC Cards
The Electronic Toll Collection (ETC) system allows you to pass through toll gates without stopping. Rental car companies rent ETC cards alongside vehicles — it is worth requesting one. ETC lanes are marked in green; cash lanes are marked in blue. Driving into an ETC lane without a card will trigger alarms and cause significant disruption behind you.
Service Areas (SA) and Parking Areas (PA)
Japan's expressway rest stops are famously excellent. Service Areas (SA) have restaurants, convenience stores, showers, and sometimes hot spring facilities. Parking Areas (PA) are smaller, with vending machines and toilets. On a long drive, stopping at a SA is a highlight in itself — regional food stalls, local souvenirs, and clean facilities make them worth the break.
4. Parking in Japan
Parking in Japanese cities is expensive and logistically complex. Unlike many countries, Japan legally requires proof of a parking space before you can register a vehicle — which gives you a sense of how serious the parking infrastructure is taken.
Coin-Operated Parking Lots (コインパーキング)
These are everywhere in Japanese cities — often small lots with a mechanical barrier plate under each space. When you pull in, the plate rises behind your rear wheels. To leave, you pay at the machine (by time, usually ¥200–¥400 per 30 minutes in central areas), and the plate lowers after payment. This system is intuitive once you understand it, but the first time it can cause mild panic when the barrier appears to trap your car.
Parking at Tourist Sites and Rural Areas
Most tourist destinations outside major cities have free or inexpensive parking. Shrines, onsen towns, and scenic viewpoints typically have dedicated lots. In rural areas, parking is rarely a problem. The challenges are almost entirely urban.
5. Navigation: Getting Around Without Getting Lost
Japanese GPS navigation is sophisticated — almost every rental car has a built-in system. However, many systems default to Japanese. Newer rental cars increasingly offer English-language navigation or allow Bluetooth pairing with Google Maps.
Using Map Codes
Japan uses a unique address system that can be confusing for foreigners. Rather than street addresses, Japanese navigation commonly uses Map Codes — a numeric code that pinpoints an exact location regardless of address ambiguity. When booking accommodations or attractions, note the Map Code if available. It can be entered directly into any Japanese car navigation system.
Google Maps
Google Maps works reliably across Japan, including on expressways and rural mountain roads. Download offline maps for your region before driving into areas with poor signal. Google Maps displays expressway toll estimates and correctly handles left-side driving navigation.
6. Rural Roads and Mountain Driving
One of the best reasons to rent a car in Japan is accessing remote areas that public transport doesn't serve well — but these roads require respect. Mountain passes (peaks, 峠) can be extremely narrow, with sheer drops on one side and no guardrails. One-lane roads with passing bays are common.
One-Lane Road Etiquette
On single-lane mountain roads, the unwritten rule is that the car closest to a passing bay backs up to let the other pass. If you are traveling downhill and there is a car coming up, uphill traffic generally has priority (it is harder to reverse uphill). Flash your lights briefly to indicate you are passing; this is a courtesy signal, not aggression.
Winter Driving
If driving in winter — particularly in Hokkaido, the Japan Alps, or Tohoku — winter tires are mandatory in snow areas. Most rental companies fit winter tires on cars rented in these regions seasonally. Always ask when booking. Chains may still be required at mountain passes even with winter tires; look for chain requirement signs (チェーン規制) before driving into mountain areas.
Frequently Asked Questions
Can I rent a car at any age in Japan?
Most car rental companies require drivers to be at least 18 or 21 years old, and some impose a surcharge for drivers under 25. Age restrictions vary by company. Check before booking, particularly for premium vehicle categories.
Which side of the car does the driver sit on?
Japanese cars are right-hand drive — the driver sits on the right side. If you are accustomed to left-hand drive cars, the gear shift (for manual) and indicator stalk will be on the opposite side to what you expect. Accidentally activating the windshield wipers when intending to signal is a universal experience for visitors from right-hand traffic countries.
Are toll roads avoidable?
Yes — national highways run parallel to most expressways and are free. They are slower due to traffic lights and lower speed limits, but are a valid option for shorter distances or scenic drives. Google Maps allows you to exclude toll roads in route settings.
What do I do if I am involved in an accident?
Stop immediately, do not move vehicles unless they are causing a hazard, call 110 (police) and 119 (ambulance) if needed, and contact your rental company's emergency line. Even a minor collision must be reported to police in Japan — leaving the scene without reporting is a criminal offense. Your rental company will walk you through the process.
Is petrol (gasoline) expensive in Japan?
As of 2026, petrol in Japan costs approximately ¥160–¥190 per liter for regular unleaded. Prices vary by region — rural Hokkaido and Okinawa tend to be slightly higher. Look for the 레귤러 (regular), ハイオク (premium), and 軽油 (diesel) labels at the pump; using the wrong fuel type is a costly mistake. Most rental cars take regular unleaded (レギュラー).
