Most foreign visitors who drive in Japan are not undone by driving on the left.
They are undone by the smaller things.
The mandatory stop at every railway crossing even when no train is coming, the drink-driving limit so low that a single beer can put you over it, or the moment they realise their home country licence is not legally sufficient on its own.
If you are planning a self-drive trip and are not yet sure what you do and do not know, read this before you book the rental car.
The Paperwork That Must Be Done Before You Leave Home
Japan does not issue International Driving Permits.
That sentence matters, because if you have not obtained one before you leave, you cannot get one once you arrive.
An IDP is a legal requirement for most foreign nationals driving in Japan, and you must carry it alongside your home country licence at all times.
Japan only recognises IDPs issued under the 1949 Geneva Convention.
IDPs issued under the 1968 Vienna Convention are not accepted, and this distinction is important because different countries issue different versions.
If you are from the United States, the UK, Australia, Canada, or most other English-speaking countries, your IDP will almost certainly follow the 1949 format.
In the US, the AAA and the AATA are the only authorised issuers.
In the UK, IDPs are available in person from participating PayPoint outlets.
While in Australia, your state or territory motoring club handles the application.
Processing is typically fast, and in most cases you can receive your IDP on the same day you apply.
There are a small number of exceptions to the IDP requirement. Drivers from Germany, France, Belgium, Switzerland, Monaco, and Taiwan do not need an IDP.
Instead, they need an official Japanese translation of their licence, obtainable through the Japan Automobile Federation or through their respective embassy in Japan.
Nationals from countries whose IDPs are not recognised by Japan at all must obtain a Japanese driver’s licence through a separate process.
Driving without a valid IDP is not a minor infraction.
It can void your rental car insurance, result in a fine, and cause your vehicle to be impounded.
This is one piece of paperwork that cannot be sorted on arrival.
What to Expect on Day One
If you come from a country with right-hand traffic, the first morning behind the wheel in Japan will feel disorienting.
The adaptation happens faster than most people expect, but the first few junctions still require conscious effort.
A rental car park is actually a useful starting point because it is low-speed and low-pressure, and by the time you have made your first few turns on public roads you will have found your bearings.
A useful mental anchor: the driver is always closest to the centre line of the road.
Keeping this in mind, especially when turning or pulling out from a stop, helps prevent the instinct to drift wide. The moments that catch people out are rarely on open roads.
They tend to happen after a pause, when pulling out of a car park or a petrol station onto a quiet road where there is no other traffic to follow and instinct briefly overrides logic.
Slow down, pause, and look deliberately before committing to a direction.
The vast majority of rental cars in Japan are automatic, so you will not need to operate a gear stick with the unfamiliar hand.
That removes one variable entirely and makes the first day considerably easier.
Key Differences From Driving at Home
Before looking at each rule in detail, here is a quick summary of what is genuinely different in Japan compared to most Western countries:
- No turn in any direction is permitted on a red light unless a green arrow signal is displayed. There is no left-on-red provision equivalent to the US right-on-red rule.
- All vehicles must come to a complete stop at every railway level crossing, regardless of whether barriers are up or down and whether or not a train is visible.
- The drink-driving limit is a blood alcohol concentration of 0.03%, far lower than the UK limit of 0.08%, the US limit of 0.08%, or Australia’s 0.05%.
- Highway directional signs are green. General road signs are blue.
- Stop signs in Japan are red downward-pointing triangles, not the octagonal signs used in the US or much of Europe.
- Japan drives on the left, with the steering wheel on the right.
Speed Limits by Road Type
Speed limits in Japan are lower than many visitors expect, particularly in urban areas.
Posted signs always override the defaults below.
Where no sign is displayed, these statutory limits apply:
| Road type | Default speed limit |
|---|---|
| Residential and side streets | 30 km/h |
| Urban two-lane roads | 40 km/h |
| Ordinary roads (no posted sign) | 60 km/h |
| Undivided expressways | 70 km/h |
| Divided national expressways | 100 km/h |
| Selected expressway sections | Up to 120 km/h |
In practice, the expressways you will use as a visitor are most commonly posted at 100 km/h.
On rural ordinary roads, 60 km/h is the default in the absence of a sign.
Urban streets are frequently posted at 40 km/h.
Enforcement is by speed camera and patrol, and sticking to posted limits is the simplest way to stay out of any difficulty.
Getting On and Off the Highway
Japanese expressways are toll roads.
The toll is calculated by distance and vehicle class.
For a standard passenger car on regular expressway sections, the rate runs to approximately 25 yen per kilometre, with slightly higher rates in the Tokyo and Osaka metropolitan areas.
When joining an expressway, follow the green directional signs.
At the entry interchange, collect a ticket from the automated machine and keep it safe.
You present it at the exit gate and pay the fare there.
Do not enter a lane marked with a purple ETC sign unless your rental car has an ETC card reader and an active card inserted.
Paying a Cash Toll at the Exit Gate
- Move into a lane marked in green, usually labelled 一般 (ippan), meaning general use.
- Stop at the gate and hand your entry ticket to the attendant, or insert it into the machine.
- The display will show the amount owed.
- Pay in cash or by credit card. Cash must be in Japanese yen.
- Collect your change and receipt, then proceed when the barrier rises.
Most attended gates have staff who can process the payment without any Japanese conversation being required on your part.
The ETC Card: Is It Worth Adding to Your Rental?
ETC is Japan’s electronic toll collection system.
Cars fitted with an ETC reader can pass through the purple-signed gates at reduced speed, around 20 km/h, without stopping.
The charge is deducted automatically.
For a short trip with occasional highway use, a cash gate is perfectly manageable.
For multi-day drives covering significant distances, an ETC card is worth the additional cost.
Rental agencies offer ETC cards separately from the vehicle itself, and toll charges accumulate during your rental before being settled when you return the car.
ETC gates also offer discounts during late-night hours and on public holidays, which adds up meaningfully over longer journeys.
Ask your rental agency about terms and current rates when you collect the vehicle.
Fuel: Knowing Which Pump to Use
Most rental cars in Japan run on regular petrol.
Diesel personal vehicles are uncommon, and you are very unlikely to need a diesel pump.
At self-service stations, nozzles are colour-coded:
| Nozzle colour | Fuel type | When to use it |
|---|---|---|
| Red | Regular petrol | Most rental cars |
| Yellow | High-octane (premium) petrol | Performance vehicles that specify it |
| Green | Diesel | Trucks and diesel vehicles only |
Confirm the correct fuel type with your rental agency before your first fill-up.
Putting diesel into a petrol engine causes serious damage and is not covered by standard rental insurance.
Full-service stations are common outside major cities.
At a full-service station, an attendant will handle the fuelling for you:
- Pull up alongside the pump. An attendant will direct you into position.
- Turn off the engine when prompted.
- Tell the attendant the fuel type and quantity. Saying “Regular, mantan, onegaishimasu” covers the essentials and means full tank of regular petrol, please.
- The attendant fills the tank, takes payment, and often cleans the windscreen.
- Both cash and credit cards are accepted at most stations.
Self-service stations are increasingly common, particularly in cities.
The pump screen is often Japanese only.
Select the button matching your fuel type colour, follow the prompts for payment and quantity, and look for a mantan option if you want a full tank.
Railway Level Crossings: The Rule Most Visitors Do Not Know
Under Japanese law, every vehicle must come to a complete stop before crossing any railway level crossing.
This applies even when the barrier is raised.
It applies even when no train is visible and even when the car in front of you has just crossed without stopping.
It is not optional, and it is enforced.
The law exists because automated crossing signals can malfunction.
An incident in early 2024 saw a barrier rise while a train was still approaching, caused by a circuit breaker fault from overnight maintenance work nearby.
The driver of the waiting car moved forward, and the train driver narrowly avoided a collision by applying emergency braking.
The mandatory stop requirement puts the responsibility for checking directly on the driver, not on the equipment, and that is precisely why it exists.
The procedure at a crossing is to stop before the line, look in both directions, listen, and only then proceed.
Cross promptly once you are satisfied it is clear, and do not stop on the tracks themselves.
Drink-Driving: The Law Is Stricter Than You Think
Japan’s blood alcohol concentration limit for drivers is 0.03%.
That is less than half the limit in the UK or US, and well below Australia’s 0.05%.
For an average adult weighing around 65 kg, one standard-size can of beer can be sufficient to exceed the legal limit.
The consistent message from every authoritative source, including the Japan Automobile Federation and Japanese law enforcement, is straightforward.
If you plan to drive, do not drink.
| Offence | Threshold | Maximum penalty |
|---|---|---|
| Driving under the influence (DUI) | 0.03% BAC or 0.15 mg/L breath | 3 years imprisonment or fine up to 500,000 yen |
| Driving while intoxicated (DWI) | Visible impairment, regardless of BAC | 5 years imprisonment or fine up to 1,000,000 yen |
| Causing death or injury while impaired | Either category | Up to 20 years imprisonment |
Passengers who knowingly allow an intoxicated person to drive can also face legal consequences.
Japanese law makes no exception for tourists.
A conviction as a foreign visitor will affect future eligibility to return to Japan.
No Turn on Red
In Japan, a red light means stop in every direction.
There is no left-on-red provision equivalent to the right-on-red rule common in North America.
When a signal is red, all vehicles moving straight, turning left, or turning right must wait for green.
The only exception is an intersection where a specific green arrow signal is displayed alongside the red, which permits movement only in the direction of that arrow.
When turning right across oncoming traffic on a green light, move to the centre of the intersection and wait for a clear gap before completing the turn.
Oncoming traffic has priority.
This is different from the approach in some countries where right-turning vehicles have a dedicated protective phase, and new arrivals who assume they can complete the turn promptly will find Japanese drivers do not expect them to move.
Do You Actually Need a Car?
If your itinerary centres on Tokyo, Kyoto, Osaka, or Hiroshima, you do not need a car.
Japan’s rail network connects these cities efficiently, and urban public transport in major cities is comprehensive and reliable.
A car in central Tokyo would create more problems than it solves, and parking costs in major cities are significant.
Where a car earns its place is in areas that trains do not reach conveniently.
Rural Tohoku, the Noto Peninsula, the mountain valleys of Nagano and Gifu, the interior of Hokkaido, the farming communities of Kagoshima, the hot spring towns of Oita that sit well off the main rail lines.
These are the places where a rental car changes the trip entirely.
You can set your own pace, stop where you want, and reach accommodation that would otherwise require a lengthy taxi ride from the nearest station.
Narrow rural roads are worth knowing about in advance.
Many are single-lane with passing places.
When an oncoming vehicle appears, pull as far left as possible and slow to a crawl.
The vehicle travelling uphill generally has priority.
Most encounters are quick, and drivers in rural Japan tend to be patient with visitors navigating unfamiliar terrain.
Before You Leave: What to Have in Place
- International Driving Permit. Obtain this from your country’s authorised issuing body before departure. Carry it alongside your home country licence at all times in the car.
- Convention check. Your IDP must follow the 1949 Geneva Convention format. Drivers from Germany, France, Belgium, Switzerland, Monaco, and Taiwan need a JAF licence translation instead of an IDP.
- Fuel type confirmed. Ask your rental agency which fuel your car requires and note it in your phone before you drive away.
- ETC card. If you plan to use expressways on multiple days, ask your rental agency about adding an ETC card at the time of booking.
- Navigation. Google Maps works well in Japan with English language settings. Download offline maps for rural areas before you lose mobile signal on mountain roads.
- Cash. Some toll booths and rural petrol stations are cash only. Carry Japanese yen.
- Insurance check. Confirm exactly what your rental cover includes and whether it remains valid if you drive without a valid IDP.
The first morning is the most demanding part of any self-drive trip in Japan.
Plan a simple route, avoid rush hour if possible, and give yourself time to adjust to the car and the roads before attempting anything complex.
By the second day, the mechanics will feel considerably more natural, and you will have the mental space to notice what is outside the windows rather than just what is in front of them.
