The 10 Most Common Mistakes Travelers Make When Driving in Japan (and How to Avoid Them)
Introduction
Driving in Japan can transform a trip into a much freer experience. With a car, you can explore rural areas, coasts, lakes, remote onsen, or regions like Hokkaido with a flexibility that trains don't always offer.
But this freedom comes at a price: you need to prepare your trip seriously. Many travelers still underestimate the necessary documents, driving on the left side, the actual budget, or the very specific restrictions associated with holidays, weather, or local rules. Here are the 10 most common mistakes — and how to smartly avoid them.
Mistake 1 — Believing that the international driver's license is always sufficient
This is probably the most common mistake. Many travelers think that an international driver's license is automatically enough to drive in Japan. In reality, this is not the case for everyone.
For some nationalities, especially several European countries, the official JAF translation of the national driver's license is essential. Setting off with the wrong documents can block you at the car rental counter, even if your reservation is confirmed.

Mistake 2 — Starting the JAF translation too late
Another classic mistake: putting off the translation of the driver's license until the last days. At first, it seems simple. But as the departure day approaches, it becomes an urgent formality that must be completed between packing, reservations, work, and the entire trip planning.
This rush increases the risk of errors: missing files, blurry scans, inconsistent names, incomplete documents. A manageable formality then becomes a disproportionate source of stress.

Mistake 3 — Thinking that the translation application will be automatically accepted
Submitting an application does not mean it will be immediately accepted without questions. If the scans are of poor quality, a document is incomplete, or certain information is unclear, your application may be delayed.
This is not necessarily a final rejection, but every back-and-forth reduces your safety margin before departure. Therefore, this process should be taken seriously from the start.

Mistake 4 — Underestimating driving on the left side
Driving on the left side is not a simple detail. It's a real change in habits. You have to think differently at intersections, in curves, when positioning on the road, and in roundabouts (by the way, I don't think I've ever seen a roundabout in Japan 🤷🏻♀️ ^_^).
The difficulty is even greater after a long flight, with jet lag, luggage, sometimes children, and the fatigue at the start of the trip. So it's not the best time to improvise a long drive.

Mistake 5 — Underestimating holidays and peak times
Many travelers plan their route according to their own calendar... but forget to consider the Japanese one. The country has 16 national holidays, and roads as well as public transport can be much busier during these times.
The official Go Tokyo website also reminds us that roads and public transport can be overcrowded during Japanese holidays. If you add Golden Week, Obon, New Year, or some long weekends to this, you can quickly face traffic jams, fully booked accommodations, and crowded parking lots.

Mistake 6 — Underestimating the actual preparation of the road trip
“With a car, we'll improvise.” This idea is tempting but doesn't work well in Japan if the route isn't at least somewhat thought out.
Driving times, road closures, gas stations on certain routes, arrival times at accommodations, parking availability, or even the weather can change everything. A good road trip allows for flexibility but is still based on a clear framework.

Mistake 7 — Not respecting the rules, speed limits, and local realities
The JAF reminds drivers to adhere to the posted speed limits, and if no sign is present, the general limit for ordinary cars is 60 km/h on regular roads and 100 km/h on highways. These speeds may seem low to some travelers but must be followed.
The JAF also reminds us that driving under the influence of alcohol is prohibited. Penalties in Japan are strict: From 0.15 mg of alcohol per liter of exhaled air, driving under the influence is punishable by imprisonment and fines according to OIST. In practice, the only good strategy is simple: do not drink at all before driving.

Mistake 8 — Underestimating tolls and fuel in the budget
The rental price is only part of the actual budget. Many travelers forget to account for tolls, fuel, parking, certain insurances, or even the fees for returning in another city.
Often, the “reasonable” budget becomes a surprise at this point. The longer your route, the more expensive this mistake will be.

Mistake 9 — Driving Off Without Checking the Rental Conditions
A driver's license and a credit card aren't always enough. Some agencies require a minimum age, charge fees for young drivers, demand a specific type of card, or require sufficient funds to cover the deposit, insurance, and unforeseen expenses.
If you discover these conditions too late, you might find yourself stuck at the counter despite having a proper reservation.

Mistake 10 — Ignoring the Weather and Not Planning License Conversion if Staying Longer Than a Year
Weather plays a much more important role on a road trip than you might think. Humid heat, rain, fog, late snowfalls depending on the region, seasonal typhoons, limited visibility, or climate-induced fatigue can completely change your driving comfort and pace.
If you are staying longer than a year in Japan, it's not just about renting or translation anymore: you need to learn about the conversion of a foreign driver's license to a Japanese license, known as Gaimen Kirikae. Delaying this issue for too long can make your life administratively difficult on site.
Things to Keep in Mind
In summary, most problems rarely stem from the driving itself. They mainly arise from a lack of preparation regarding documents, on-site realities, budget, and travel pace.
To avoid these mistakes:
- Check your documents early;
- Plan your route realistically;
- Strictly adhere to traffic rules;
- Consider holidays and weather conditions;
- and always maintain a mental, logistical, and financial buffer.
