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

For a Canadian driver, the paperwork for Japan is simpler than the rumours suggest — and the real challenge is what happens once the car is moving. Canada signed the 1949 Geneva Convention, the only treaty Japan recognises for foreign permits, so an ordinary International Driving Permit picked up from CAA before you leave is all you need. There is no requirement for an official Japanese translation, unlike the headache Swiss or German visitors face.

Carry three documents together: the Geneva IDP, your provincial licence and your passport. The permit is valid for stays of up to 12 months, which covers any holiday. Arrange it in Canada — it is not issued anywhere in Japan, and a rental desk will turn you away without it. You can confirm exactly what your licence needs with the Driving Permit Checker.

The genuine adjustment is the side of the road. Canada drives on the right; Japan drives on the left. The danger window is your first hour — pulling out of a car park, taking a turn, or reaching for the indicator and hitting the wipers instead (the stalks are mirrored on most Japanese cars). Pick the car up somewhere quiet rather than central Tokyo, and talk yourself through each turn until left stops feeling wrong.

Then there is alcohol. Japan runs a 0.03 BAC limit against Canada’s 0.08, and the country takes drink-driving extraordinarily seriously: heavy fines, immediate licence confiscation and, for higher readings, detention. Passengers who knowingly ride with an over-limit driver can also be penalised. The only safe rule is nothing at all before you drive.

Speeds run low by Canadian standards — 40 km/h in towns, 60 on rural roads and 100 on the expressways, which are excellent but heavily tolled (an ETC card in the rental saves time at the gates). Fixed and mobile cameras are common, and a typical 10 km/h overspeed costs around JPY 9,000 (≈ €55) plus a point. You can sanity-check a penalty with the Speeding Fine Calculator.

Petrol is roughly $1.35/litre, the emergency number for police is 110 (ambulance and fire are 119), and you should carry the warning triangle the car comes with. For the full rules, see our Japan driving guide.
