Parking Rules for Campervans

Proper parking is crucial to avoid fines and towing

Tolls, Highways & ETC System

Toll Roads Network

Japan drives on the LEFT side of the road. Take extra care at intersections and when merging.

ETC Card System

Electronic Toll Collection (ETC) cards offer discounts and faster passage. Most rental campervans come equipped with ETC devices. Ask your rental company for an ETC card.

Payment Options

Cash is accepted at toll booths, but ETC lanes are faster and often cheaper. Keep yen handy if not using ETC. Some expressways have unmanned gates.

Plan your route and check toll costs in advance using the NEXCO website or apps. Weekend and holiday discounts are often available with ETC.

Alcohol, Seatbelts & Safety Rules

Zero Tolerance Alcohol

Japan has a zero-tolerance policy for drinking and driving. Any detectable amount can result in severe penalties, including arrest and deportation.

Seatbelt Requirements

Seatbelts are mandatory for all passengers, including those in the back seats. Children under 6 must use appropriate child safety seats.

Emergency Numbers

Police:110
Fire/Ambulance:119
Emergency (English):#9110

• Mobile phone use while driving is illegal (use hands-free only)
• Keep headlights on in tunnels and bad weather
• Winter tires or chains required in snowy regions
• Insurance coverage is mandatory – verify with your rental company

Important Tips for Foreign Drivers

Remember:

Take your time to adjust to left-side driving. It’s better to drive slowly and carefully than to rush
and make mistakes.
