Driving in Japan as an American: What to Know Before Renting a Car

But the first mistake can happen before that. You can arrive with a US driver's license and a rental reservation, then discover that your international driving permit is not the version Japan accepts.

The idea is narrower than becoming an expert on every Japanese road. Confirm the documents, choose a first drive that does not ask too much of you, and rehearse the moments where your usual driving habit is most likely to return.

Start with the document Japan actually accepts

For most visitors driving on a US license, Japan requires a valid US driver's license plus an International Driving Permit issued under the 1949 Geneva Convention. The permit needs to be the paper booklet type, obtained before departure. A card or smartphone version is not valid for driving in Japan. Carry your original license as well. JNTO's rental-car guidance explains the requirement, and USAGov identifies AAA and AATA as the two US State Department-authorized IDP issuers.

There is a separate Japanese-translation route for licenses issued in France, Switzerland, Germany, Belgium, Monaco, and Taiwan. That is not the usual route for an American license, but it is a useful reminder that the answer depends on where your license was issued, not where you live.

Put these items together before you fly:

• Your valid US driver's license
• Your paper 1949 Geneva Convention IDP
• Your passport
• Your rental reservation and the rental company's current terms

One small detail is worth checking. JNTO says the period is linked to the date of arrival shown by your passport entry stamp. If you pass through an automated arrival gate without a stamp, ask at the customs inspection desk before leaving the airport. Do not leave the counter question until your rental pickup.

Japan changes the road side and the driver position

Japan drives on the left. The driver's seat is on the right.

Those are two different changes. Keeping left tells you where the car belongs on the road. Sitting on the right changes how the curb, center line, and lane markings look from your seat.

The first time I drove on the left, I had an accident while taking a right turn. I looked the wrong way for oncoming traffic. I knew the rule. The problem was habit.

That is why the first drive deserves a plan. You are not learning to drive from the beginning. You are making a familiar sequence deliberate for a short time.

Before you move, sit in the parked car and do four things:

1. Adjust the seat and mirrors.
2. Find the indicators, lights, parking brake, and gear selector.
3. Notice where the left curb and center of the road appear from the driver's seat.
4. Say your first move out loud: “I am joining the left lane.”

It may feel slightly formal. That is the point. You are giving your attention one job before navigation, luggage, and a new car compete for it.

Choose a car only where it helps your itinerary

Japan has strong public transportation in its major cities. A rental car has a clearer job when your itinerary reaches rural or nature areas, where public transportation may be limited. JNTO's travel FAQ makes the same distinction.

That does not mean a rental car is wrong in a city. It means you do not have to make your first drive the most complicated part of the trip.

Ask two practical questions before booking:

• Is the car for a part of the route where it solves a real transport problem?
• Can I collect it after the city portion of the trip, or choose a pickup location with a simple first route?

A calmer first drive might be a daylight route from a smaller pickup location to one nearby destination. It does not need to begin with a dense city center, hotel search, and a tired driver trying to learn a new traffic pattern at the same time.

Treat the first ten minutes as a practice route

The goal of the first drive is not to make progress quickly. It is to establish the pattern you will repeat.

Use this sequence each time you pull out or turn:

1. Stop and identify the lane you want to enter.
2. Check traffic and the road markings.
3. Move only once the lane choice is clear.
4. After the turn, ask: “Where am I now?”

That last question matters. A turn can feel complete while your old road-side habit is still making the next choice for you.

If you rent an automatic car, you remove one unfamiliar task while you are adapting to a different driving position and traffic pattern. It is not a requirement. It is one way to leave more attention for the road.

Learn the local rules before you depend on memory

Your US driving experience helps, but it does not replace Japanese road rules. JAF's English-language guidance says drivers must keep left, yield to pedestrians, wear seatbelts, and avoid using a phone or being distracted by car navigation while driving. It also says that where no speed limit is signed, the limit for regular-sized automobiles is 60 km/h on ordinary roads and 100 km/h on expressways. Signed limits still control. Read JAF's traffic rules before your trip.

For expressways, JAF says to use the passing lane only for overtaking and return to the driving lane. It also advises drivers to refuel in advance on routes where service stations may be far apart.

Do not assume every sign will answer itself in English. JNTO says major destinations are signposted in English on main roads, while rural areas may be different. Set your navigation before moving and look up the local rules for the actual region you will drive in.

Make the rental counter part of the preparation

The rental agreement is where you confirm the trip you have planned is the one the company will support.

Before leaving the lot, confirm:

• The documents the company needs from every listed driver
• The fuel type for the car
• Existing scratches or dents, with the staff present
• The insurance coverage and exclusions in your own booking
• How to get help if the car has a problem
• Whether your planned route has a toll or payment arrangement you need to understand

JNTO notes that rental insurance conditions vary by company and recommends checking the car for damage with staff before departure. JAF also provides English guidance on self-service fuel, including checking the correct fuel type for a rental car.

This is not paperwork for its own sake. It is how you avoid having to solve a new problem while your attention should be on the road.

Practice the habit change before pickup day

Written advice can tell you that Japan drives on the left. It cannot make your first pullout, turn, or roundabout feel familiar.

That is the narrower goal of LeftLane's driving-on-the-left guide and browser practice. The free scenarios let licensed drivers rehearse specific decisions before rental pickup. They do not replace local rules, professional instruction, or the judgment needed on a real road.

If you are planning to rent in Japan, do this before you leave:

1. Get the right paper IDP and place it with your original license and passport.
2. Read JAF's current national traffic rules, then check the signs, weather, and route conditions for the roads you will use.
3. Pick a first route that gives you time to settle into the left lane.
4. Rehearse pulling out, turning, and checking your road position after every maneuver.

You do not need to be fearless at the rental desk. You need a plan that leaves less to habit.
