🚗 Driving in Japan as Canadian? Yes—IDP + 0.03 BAC

Can Canadians drive in Japan? Yes, and the paperwork is easier than for many other nationalities. Japan accepts foreign permits only under the 1949 Geneva Convention, and Canada is a party to that treaty, so the standard International Driving Permit issued in Canada is valid. Carry it together with your provincial licence and your passport. It covers driving for up to 12 months. Your licence alone will not do, and no Japanese translation is needed on top.

The three documents in your pocket

The permit is the part people leave too late. It can only be issued in Canada, so it must be in hand before the flight; there is no way to obtain one after landing in Tokyo or Osaka. Rental desks in Japan check it carefully, and a missing or expired permit ends the booking on the spot. Lay out permit, licence and passport together at the counter, and keep them together in the car. The Driving Permit Checker confirms what else your licence needs if the trip continues to Korea or Taiwan.

Left side, mirrored stalks

Canada keeps right; Japan keeps left. You sit on the right of the car and turn across traffic when turning right. Most Japanese cars also swap the stalks, so the first time you signal you will probably switch on the wipers. Everyone does it. The real risk is a turn into an empty street, where nothing reminds you which lane is yours. Collect the car away from central Tokyo if you can, and talk yourself through the first dozen turns.

Narrow roads and low limits

Global Affairs Canada describes Japan’s roads as generally good but warns that some are narrow, especially in residential and rural areas. The speed limits reflect that:

• Ordinary roads: 60 km/h by default
• Streets without a centre line, or where signed: 30 km/h. From September 2026 that lower default applies to narrow residential roads.
• Expressways: 100 km/h, with 120 km/h on designated sections such as the Shin-Tomei, Tohoku and Joban

For someone used to 80 on a provincial two-lane highway, 60 feels slow. Keep to it anyway. Expressways are excellent and tolled; an ETC card in the rental car lets you pass the gates without stopping.

For live traffic and closures, Global Affairs Canada points to the Japan Road Traffic Information Center. Its site is in Japanese only, so a browser translation tool helps. On mountain and coastal routes in the countryside, the narrow sections often have no room for two cars to pass; pull into the nearest wider spot and let the oncoming driver through.

What a speeding ticket costs

Japan’s fixed fines climb in steps:

Beyond 30 km/h over on an ordinary road, or 40 over on an expressway, the matter becomes criminal rather than a ticket. Holding a phone while driving costs JPY 18,000 plus 3 points. Try the Speeding Fine Calculator for other bands.

Alcohol: 0.03 and no grace

Japan’s limit is 0.03 BAC, under half of Canada’s federal 0.08. Enforcement is severe: heavy fines, licence confiscation and detention at higher readings, and passengers who knowingly ride with an over-limit driver can be penalised too. A beer with ramen at lunch is a bad idea if you are driving afterwards. Order the tea, and save the beer for the evening once the car is parked for the night.

Equipment and phone numbers

The only item the car must carry is a warning triangle; your rental will have one. Japan splits its emergency calls in a way Canadians will need to memorise:

• Police: 110
• Ambulance and fire: 119

Put both numbers in your phone before leaving the rental lot. The Japan driving guide covers road signs, tolls and parking.
