Japan’s trains are famously good, which is exactly why most visitors never consider a rental car — and exactly why they miss the parts of Japan that trains don’t reach. The Iya Valley’s vine bridges, Noto Peninsula’s coastline, and back roads through the Japan Alps open up dramatically once you’re driving. But renting a car in Japan has a few rules that trip up first-timers, starting with the one document almost everyone forgets.
Do You Need an International Driving Permit?
Yes — and you must get it before you land. Japan recognizes the 1949 Geneva Convention International Driving Permit (IDP), which you apply for through your home country’s motoring authority (AAA in the US, CAA in Canada, the AA or RAC in the UK, and so on). It typically costs $20–35 USD equivalent and is issued same-day, valid for one year. Japan cannot issue one to you on arrival, and airport rental counters will turn you away without it.
There’s one major exception: drivers licensed in France, Germany, Switzerland, Belgium, Monaco, and Taiwan aren’t part of the Geneva Convention system. Instead, you need an official Japanese translation of your home license, obtainable from the Japan Automobile Federation (JAF) or your country’s consulate in Japan. Everyone else — US, UK, Canada, Australia, most of Europe, Southeast Asia — needs the IDP. Bring your physical home license too; the IDP alone isn’t valid without it.
Most companies require drivers to be at least 18, and some (particularly for larger vehicles or campervans) want at least one year of driving history on your home license.
Choosing a Rental Company and What It Costs
The big national chains — Toyota Rent a Car, Nippon Rent-A-Car, Times Car Rental, Orix Rent-A-Car, and Nissan Rent-A-Car — all have English-language websites and counters at major airports and train stations, which makes them the easiest starting point. Prices for a 24-hour rental typically run:
- Budget: Kei car (yellow-plate minicar, seats 4) — around ¥5,000–6,500/day. Cheap and easy to park, but underpowered for mountain passes or highway merges with luggage aboard.
- Mid-range: Compact sedan or hatchback (Toyota Yaris, Honda Fit class) — ¥6,500–9,500/day.
- Splurge: SUV or minivan for groups, or a premium model — ¥12,000–20,000+/day.
On top of the base rate, budget for Collision Damage Waiver insurance (¥1,000–2,000/day, often bundled in but confirm) and the Non-Operation Charge waiver (NOC, roughly ¥1,000–1,500/day) — without the NOC waiver, you’re liable for the company’s lost rental income if the car is damaged, even with CDW covering repairs. Renting an ETC toll card costs a flat ¥300–330. If you’re picking up in one city and dropping off in another, expect a one-way fee of ¥10,000–30,000+ depending on distance.
Tolls, Gas, and Parking: The Hidden Costs
Japan’s expressways are toll roads, and the tolls add up fast — Tokyo to Nagano runs roughly ¥5,000 one-way, for example. Get the ETC card and use the dedicated ETC lanes at tollgates; it deducts automatically and saves you from fumbling for cash at 80 km/h. Regular gasoline (レギュラー) runs around ¥170–185 per liter as of 2026; rental cars are returned with a full tank, so budget the equivalent of a top-up right before drop-off, or you’ll be charged a premium rate for the difference.
Parking is the cost visitors underestimate most. Central Tokyo, Kyoto, and Osaka charge ¥300–500 per 30 minutes at coin parking lots (coordinated by locking wheel-lock systems), and can hit ¥2,000–3,000 for a full day even outside the very center. If your itinerary is mostly cities like Kyoto or Osaka, a car is often more hassle than help — save it for the legs where public transit thins out, and lean on regional IC cards for the city portions.
Rules of the Road
Japan drives on the left, with the steering wheel on the right side of the car. Expressway speed limits are generally 80–100 km/h, and city/rural roads 30–60 km/h — enforced strictly, with speed cameras common. Drink driving has a zero-tolerance policy with serious penalties even at low blood alcohol levels; if you’re planning an onsen town stop with dinner and drinks, don’t plan to drive afterward.
Rental car navigation systems are usually in Japanese by default; ask staff to switch the language, or simply enter your destination’s phone number or a MAPCODE, which the nav systems handle more reliably than romanized addresses. Many rentals now include CarPlay/Android Auto, letting you run Google Maps from your phone instead. If you’re heading into snow country (Tohoku, Hokkaido, the Japan Alps) between December and March, confirm the car comes with studless winter tires — reputable agencies swap them automatically in season, but it’s worth asking outright.
Common Mistakes to Avoid
- Arriving without the IDP. This is the single most common reason travelers get turned away — and it can’t be fixed once you’re in Japan.
- Renting a car for a city-heavy itinerary. If you’re mostly hopping between Tokyo, Kyoto, and Osaka, trains and buses (see our guide to overnight buses in Japan) are cheaper and less stressful than parking fees and tolls.
- Skipping the pre-rental damage walkaround. Photograph every scratch with the staff present before driving off.
- Ignoring narrow rural roads. Many countryside roads are one-lane with passing bays; go slowly and be ready to reverse.
- Not checking earthquake and typhoon contingencies. If you’re driving through rural or coastal areas, it’s worth a quick read of our earthquake and disaster prep guide before you set off.
Best Road Trips by Rental Car
A few regions genuinely reward having your own wheels:
- Shikoku: The smallest of Japan’s main islands has patchy rail coverage but spectacular driving — the vine bridges and gorges of the Iya Valley, the Naruto whirlpools, and stretches of the 88 Temple Pilgrimage route are all far easier by car. See our full Shikoku travel guide.
- The Japan Alps: Base yourself in Matsumoto and drive into the mountains for alpine scenery that’s a real slog by bus, especially outside peak season.
- Yakushima and Sado Island: Both islands are compact enough to circle in a day or two by car, and both have limited public transit once you’re off the main port town — see our guides to Yakushima’s ancient forests and Sado Island.
Best timing for road trips is spring (April–May) and autumn (October–November), when mountain passes are clear and scenery is at its best; midsummer is fine but hot and humid for stops outside the AC, and winter driving in the Alps or Tohoku requires real snow-driving confidence even with the right tires. Whatever the season, book your car at least a few weeks ahead for the busiest windows — Golden Week (late April–early May), Obon (mid-August), and New Year — when fleets sell out at popular pickup points.
