Japan is made for scenic drives: alpine passes in Nagano, Hokkaidos flower fields, Kyushus steaming onsen valleys, and tiny seaside towns youd miss by train. Renting a car opens up all of that flexibility, but the rules and road culture are a little different. Here are practical, road-tested tips to help you rent confidently and drive smoothly across Japan.

Licenses and paperwork

• You must be 18+ to drive. Most agencies require a credit card and at least one year of licensed driving.
• Bring your passport and your home-country drivers license.
• Most travelers also need an International Driving Permit under the 1949 Geneva Convention. Do not get the 1968 versionit is not accepted.
• Drivers from Belgium, France, Germany, Monaco, Switzerland, and Taiwan use their national license with an official Japanese translation (from JAF or their embassy) instead of an IDP.
• Check the latest rules with JAF or your rental company before you fly; requirements change and are enforced.

Choose and book the right car

• Size matters on Japans narrow lanes. A compact or small SUV is easier to park and thread through countryside villages.
• Confirm English navigation or plan to use Apple CarPlay or Android Auto. Mapcode support is handy for pinpointing sights and parking.
• Reserve an ETC card with your rental. It lets you breeze through toll gates and often qualifies you for expressway pass deals.
• Consider insurance beyond basic CDW. Ask about NOC (non-operation charge) waivers that reduce penalties if the car needs repair.
• One-way rentals are common at airports and shinkansen hubs but may carry drop feesfactor that into your route.

Road rules and etiquette

• Drive on the left; the drivers seat is on the right. Roundabouts are rare; most intersections use signals.
• Typical speed limits: 3030 km/h in towns, 506 km/h on rural roads, 80100 km/h on expressways. Cameras are common; fines are steep.
• Seat belts are mandatory for all seats. Children under 6 must use an approved child seat.
• Alcohol limit is very low (0.03% BAC). Treat it as zeronever drink and drive.
• Use turn signals early, avoid honking, and expect courteous merges. A quick flash of hazard lights is a common thanks on expressways.
• Headlights on in tunnels and during heavy rain. Watch for pedestrians and cyclists on narrow shoulders.

Tolls, passes, and navigation

• Expressways are tolled. With an ETC card in the dash reader, you can use purple ETC lanes without stopping; charges settle to your card later.
• Tourist expressway passes (nationwide or regional, e.g., Hokkaido, Kyushu) offer unlimited tolls for a fixed daily fee when renting from participating agencies. Do the math: long-haul itineraries usually save.
• Rest areas are excellent: SAs (service areas) and PAs (parking areas) have clean bathrooms, food courts, fuel, and souvenir shops.
• Addresses in Japan can be tricky. Enter a phone number or a Mapcode into the cars nav, or pin exact locations in your phone maps.

Parking and fueling

• Street parking is rare and risky. Use coin-operated lots or multi-story garages; expect locking plates under the wheels in coin parks.
• Hotel parking isnt guaranteed in big cities. Reserve in advance and check height limits for mechanical elevator garages.
• Keep coins or a transit IC card for small parking fees. In some rural spots, youll pay with cash at an unmanned box.
• Fuel types: Regular, High Octane, and Diesel. Many stations are self-serve; full-serve attendants will guide you precisely into position.
• Rural stations may close early. Top up before remote drives or after 8 p.m. outside cities.

Seasonal and safety tips

• Winter (Hokkaido, Tohoku, Nagano): Request studless snow tires and consider chains for mountain passes. Drive gently and increase following distance.
• Typhoon season (late summer): Check road closures and ferry cancellations; avoid coastal roads during storms.
• Michi-no-Eki roadside stations make perfect pit stops with local snacks, clean toilets, and free maps.
• In a breakdown or accident, move to a safe spot if possible, set your hazard lights and warning triangle, and call 110 (police) or 119 (ambulance/fire). Contact your rental company immediately.
• Carry essentials: international SIM or pocket Wi-Fi, offline maps, a coin stash, tissues, and a reusable bag for car trash.

With the right documents, an ETC-equipped compact car, and a grasp of local etiquette, driving in Japan is straightforward and deeply rewarding. Take it unhurried, plan fuel and parking ahead, and let the open road reveal hot springs, farm-fresh lunches, and viewpoints youll have all to yourself.
