Driving in Japan is generally safe and straightforward, but it comes with specific rules and cultural norms that differ from other countries. This guide covers everything you need to know before getting behind the wheel.
License Requirements
To drive in Japan, you need one of the following:
- Japanese driver's license: Required for residents staying longer than one year.
- International Driving Permit (IDP): Valid for up to one year from entry date. Must be based on the 1949 Geneva Convention (not the 1926 Paris Convention). Obtain this in your home country before arriving in Japan.
- License translation: Citizens of Switzerland, Germany, France, Belgium, Monaco, and Taiwan can drive with their domestic license plus an official Japanese translation. Obtain the translation from JAF (Japan Automobile Federation) or your country's embassy.
NOTE: IDPs obtained outside your country of residence are not valid. You must get your IDP from the country that issued your regular license.
Basic Road Rules
Japan drives on the left side of the road. Vehicles are right-hand drive.
Speed limits are enforced strictly and displayed in km/h:
- Urban areas: 40–50 km/h
- Rural roads: 50–60 km/h
- Expressways: 100–120 km/h
Seatbelts are mandatory for all passengers. Children under six must use child seats.
Mobile phone use while driving is prohibited, including hands-free devices. Heavy fines apply.
Drink driving: Japan has a zero-tolerance policy. Blood alcohol limit is effectively zero. Penalties include heavy fines, license suspension, and imprisonment. Passengers can also be fined for allowing an intoxicated person to drive.
Road Etiquette
Japanese drivers follow specific unwritten rules that maintain order:
- Hazard lights: Used to say thank you when another driver lets you merge or pass. A quick flash of the hazards acknowledges their courtesy.
- Honking: Rarely used. A short beep warns of danger; prolonged honking is aggressive and avoided.
- Emergency vehicles: Pull over immediately when you hear sirens. All traffic stops to clear a path.
- Pedestrian priority: Always yield to pedestrians, even where not technically required. Crosswalks mean stop unless the pedestrian has clearly finished crossing.
- Signal early: Indicate turns and lane changes well in advance. Sudden maneuvers are considered dangerous and rude.
Traffic Signs and Markings
Most signs use international symbols, but some are unique to Japan:
- Stop signs: Red inverted triangle with "止まれ" (tomare) text. Full stop required.
- No parking: Blue circle with red diagonal slash. Stopping to load/unload is allowed; parking is not.
- No stopping: Blue circle with red X. Do not stop here at all.
- Arrow markings on lanes: Indicate permitted directions. White arrows on the road show where you can go from each lane.
- Blue lines: Indicate designated bicycle lanes or pedestrian priority zones.
Toll Roads and Expressways
Japan's expressways (高速道路, kōsoku-dōro) are extensive but expensive. A cross-country trip can cost ¥20,000–¥40,000 in tolls alone.
Electronic Toll Collection (ETC):
- ETC cards allow automatic toll payment at speed.
- Rental companies provide ETC cards; tolls are charged to your credit card after return.
- Without ETC, you pay cash at toll gates. Have exact change ready, though attendants provide change if needed.
ETC discounts:
- Off-peak discounts apply on weekends and late nights.
- Some regions offer tourist passes with unlimited expressway use for a fixed period. Check regional tourism offices.
Navigation
GPS in Japanese rental vans uses Japanese by default. Some rental companies offer English-language GPS units upon request.
Recommended apps:
- Google Maps: Works well in Japan; provides turn-by-turn navigation.
- Navitime: Japan-specific navigation with accurate toll calculations and real-time traffic.
- Japan Maps by MAPLUS: Offline maps useful in rural areas with poor signal.
Map codes: Japanese car navigation systems use "Map Codes" (マップコード) — short numbers that pinpoint exact locations. Many campsites and michi no eki provide these codes on their websites.
Parking
Parking in Japan requires attention to rules and signage:
- Paid parking: ¥100–¥400 per hour in cities. Overnight parking in lots is generally prohibited unless specifically allowed.
- Michi no eki (roadside stations): Free parking, often overnight. Not all allow sleeping in vehicles; check for signs prohibiting overnight stays (禁).
- Convenience stores: Parking is for customers. Extended stays without purchasing anything may result in towing.
- No-parking zones: Strictly enforced. Illegally parked vehicles are ticketed and towed quickly, especially in cities.
- Coin parking: Insert coins or use IC cards (Suica, Pasmo) to pay. Display the ticket on your dashboard.
NOTE: See our detailed guide on places to stay with a camper for overnight parking options.
Gas Stations
Types of fuel:
- Regular (レギュラー): 89–90 octane. Most rental vans use this.
- High-octane (ハイオク): 95+ octane. Higher performance; more expensive.
- Diesel (軽油): For diesel vehicles only. Do not put in gasoline engines.
Full service vs. self-service:
- Full-service stations: Attendants pump fuel, clean windows, take payment. Common in rural areas. Stay in your vehicle unless directed otherwise.
- Self-service stations: Pump your own fuel, pay at the machine. More common in cities. Some require prepayment.
Payment: Cash and credit cards accepted. IC cards work at some stations.
Narrow Roads and Mountain Driving
Rural and mountain roads present specific challenges:
- Width: Many roads, especially in villages and mountains, are barely wider than one vehicle. Mirrors may touch vegetation. Proceed slowly.
- Curves: Blind corners are common. Honk before entering sharp curves to alert oncoming traffic.
- Single-lane bridges: Alternating traffic. Check for oncoming vehicles before entering.
- Snow: Mountain roads close in winter. Check conditions before traveling. Carry snow chains when required by road signs.
- Wildlife: Deer, boar, and monkeys cross roads, especially at dawn and dusk. Reduce speed in forested areas.
Safety Tips
- Winter tires: Mandatory in snowy regions. Rental companies fit winter tires seasonally; confirm before departure.
- Emergency kit: Rental vans should include warning triangles and reflective vests. Use them if you break down.
- Breakdowns: Call the rental company's emergency number. Most include roadside assistance in the rental fee.
- Accidents: Do not move the vehicle until police arrive (except to prevent further danger). Call 110 for police, 119 for ambulance. Contact your rental company immediately.
- Fatigue: Avoid driving long distances without breaks. Service areas (SA) and parking areas (PA) on expressways offer rest stops every 30–50 km.
