Japan’s roads reward drivers with mountain passes, smooth expressways, and spectacular scenery—but the traffic rules and road culture differ markedly from those in the United States. Use the guidance below to stay safe, legal, and relaxed on your next Drivers Lounge tour.
1. Documents You Must Carry
Item | Why it matters |
U.S. driver’s license | Confirms your driving privilege. |
International Driving Permit (IDP) | Japan recognises only IDPs issued under the 1949 Geneva Convention. Permits under the 1968 Convention are invalid. |
Passport | Verifies your entry date and visa status. |
Rental agreement & insurance card | Proof of insurance is mandatory; keep the contract in the car. |
Apply for the IDP through AAA or AATA before leaving the United States. Same-day service is available at most branches for a US $20 fee; allow at least two weeks if applying by mail.
2. Left-Side Driving: Core Adjustments
Lane position – All traffic keeps left; the steering wheel is on the right.
Turns at red lights – No right-on-red unless a green arrow or light is lit.
Stop signs – Inverted red triangles marked 止まれ (“tomare”).
Rail crossings – Come to a full stop even when the barrier is up; failure to stop carries a fine.
Expect narrow lanes in towns and mirrors on blind corners. Take them slowly until you feel the car’s left-hand dimensions.
3. Speed Limits and Enforcement
Road type | Typical limit |
Urban streets | 40 km/h (25 mph) |
Residential streets | 30 km/h (19 mph) |
Rural highways | 50–60 km/h (31–37 mph) |
Expressways | 80–100 km/h (50–62 mph); some newer sections allow 120 km/h (75 mph) |
Speed cameras, unmarked patrol cars, and roadside radar are common. Fines rise sharply with each 10 km/h increment over the limit.
4. Tolls, ETC, and Expressway Basics
Japan’s long-distance expressways are tolled (average cost ≈ ¥25 per km plus a ¥150 entry fee).
Payment options
ETC card – Slides into the in-car reader; the barrier lifts automatically and discounts apply on off-peak sections. Most rental agencies loan a card for roughly ¥330.
Cash/credit – Take a ticket at entry, hand it over with payment at exit.
Service Areas (SA) and Parking Areas (PA) every 30–50 km provide restrooms, fuel, food courts, and even showers—ideal for long stints between mountain runs.
5. Prohibited Behavior and Penalties
Offence | Key difference from U.S. rules | Typical penalty |
Hand-held phone use | Strictly banned even when stopped in traffic. | Fines up to ¥18,000 and six penalty points. |
Alcohol | Legal BAC is 0.03 % (vs. 0.08 % in many U.S. states). | Fines up to ¥1 million and up to five years’ imprisonment. |
Seat belts | Mandatory for all occupants; child seats required under six years. | Immediate roadside fines. |
Blocking intersections | Enter only if you can clear it. | ¥7,000–¥9,000 fines. |
Police conduct random breath tests at holiday checkpoints. Refusal carries the same penalty as failure.
6. Navigation & Signage
Bilingual signs (Japanese & English) appear on expressways and national routes.
Mapcodes—short numeric references—are recognised by most Japanese GPS units and help when addresses are hard to enter.
Google Maps offers reliable turn-by-turn voice guidance but may lag slightly on lane-by-lane prompts.
7. Fuel, Parking, and Everyday Logistics
Fuel types
Nozzle colour | Fuel type | Label |
Red | Regular | レギュラー |
Yellow | Premium | ハイオク |
Green | Diesel | 軽油 |
Self-service is common; press the on-screen English button if available. Major credit cards are accepted, but rural pumps may require cash.
Parking systems
Coin-operated surface lots clamp a plate under the car; pay at the kiosk before driving off. Multi-storey garages use automated lifts—wait for the rotating platform to align before entering. Illegal parking is towed quickly in cities; retrieval fees exceed ¥20,000.
8. Courtesy and Road Etiquette
Two quick flashes of the hazard lights is the customary “thank you.”
Drivers often reverse into spaces for faster exits.
Use headlights in tunnels and whenever visibility is poor—daytime running lights are uncommon.
Yield to pedestrians at zebra crossings; fines apply for failing to stop.
9. Emergency Numbers
Situation | Number |
Police / Traffic accident | 110 |
Ambulance & Fire | 119 |
Roadside assistance (JAF) | #8139 (mobile) |
Carry the rental firm’s accident report form; police reports are mandatory for any incident.
10. Quick-Reference Checklist for U.S. Drivers
IDP + U.S. license + passport
Left lane, right steering wheel
40 km/h city / 100 km/h expressway unless posted
Full stop at rail crossings
Zero-tolerance phone use; near-zero alcohol
ETC card ready, or cash for tolls
Fuel types: regular = red nozzle
Hazard flash to say thanks
Emergency? Dial 110 (police)
