Why rent a car in Japan?
Japan rewards the curious driver. Beyond the bullet trains and city subways lie quiet fishing towns, mountain onsens, farm-to-table roadside diners, and coastal roads that turn every bend into a postcard. With a rental car, you can chase sunrise over Mount Fuji, detour for a steaming bowl of ramen when you spot a local favorite, and linger at viewpoints long after the tour buses leave. It’s freedom on your schedule, in a country where roads are safe, signage is clear, and rest stops feel like tiny theme parks.
- Hokkaido: flower fields, crater lakes, and smooth highways built for big-sky road trips.
- Fuji Five Lakes: serene shores, forest shrines, and iconic mountain views at your own pace.
- Setouchi Coast: island-dotted vistas and citrus groves along a sunlit inland sea.
- Kyushu: volcano routes, steaming onsen towns, and farm roads framed by tea fields.
Licenses, roads, and rules to know
Most visitors will need a 1949 Geneva-format International Driving Permit (IDP), your valid home license, and your passport to rent and drive. Always check current requirements before you travel. Japan drives on the left, seat belts are required for all, and hands-free is mandatory if you use your phone for navigation.
- Left-side driving: Keep left; slower traffic stays to the left on expressways.
- Speed limits: typically 30–50 km/h in towns, 60 km/h on ordinary roads, 80–100 km/h on expressways unless posted otherwise.
- Tolls and ETC: Expressways use tolls. Renting an ETC card lets you pass through dedicated gates and pay later—faster and often cheaper on distance-based discounts.
- Navigation: Most rental cars offer multilingual GPS. Pin your hotel’s phone number or map code to find it fast.
- Child seats: Required for children under 6 years old; reserve in advance.
- Emergency: 110 for police, 119 for fire/ambulance. Pull over safely before calling.
Parking and fueling made simple
Avoid street parking unless clearly allowed. Use coin parking lots marked with a blue “P” or yellow signs; rates and maximums are shown at the entrance. In cities, department stores and attractions often validate parking—ask before you pay. In the countryside, roadside stations (Michi-no-Eki) offer free parking, clean restrooms, local snacks, and produce markets.
Fuel is easy: you’ll see Regular (unleaded), High-octane, and Diesel. Many stations are self-serve; others are full-service with attendants guiding you in. Pay by cash or card, and keep receipts if you need to refuel to a specific level. If in doubt, show the staff your fuel cap or say “Regular, please.”
Seasonal and regional tips
- Winter driving: In Hokkaido, Tohoku, and mountain regions, rent a car with winter tires or 4WD. Drive gently on ice, leave extra space, and watch for black ice in the shade.
- Holiday traffic: Golden Week (late Apr–early May), Obon (mid-Aug), and New Year can mean heavy congestion. Start early, use ETC lanes, and build in buffer time.
- Wildlife and rural roads: Expect deer, foxes, or boar at dawn/dusk. Use low beams in fog and slow before blind curves.
- Rest stops you’ll love: Expressway Service Areas and Michi-no-Eki have local meals, souvenirs, play areas, and even onsen in some spots.
- Etiquette: Don’t block driveways, idle engines near homes at night, or park in reserved temple/shrine spaces.

Before you go
Reserve early for peak seasons, add an ETC card, and download offline maps. Pack snacks for scenic pullouts, and keep small coins for rural parking. Then point your compass at the countryside and let the road write your itinerary. When you’re ready, book with Relax Rent-a-Car and drive Japan your way.
