Can a British Driver Drive in Japan? — IDP Required, but You Keep Left
United Kingdom
Japan
A British licence holder CAN drive in Japan, but an International Driving Permit (the 1949 Geneva version) is required alongside the UK licence — without it you cannot legally drive or hire a car. The compensation: Japan drives on the LEFT, like the UK, so there is no side switch. Watch the 0.03 alcohol limit and budget for expensive expressway tolls.
Japan is one of the best long-haul countries a British driver can self-drive — left-hand traffic, superb roads, clear lane discipline. But there is one document that makes or breaks the whole trip, so it goes first.
The IDP is required, not optional
This is the rule that strands unprepared visitors at the rental counter. To drive in Japan on your British licence you must also carry an International Driving Permit issued under the 1949 Geneva Convention. It is not a “recommended” nicety here — without it you cannot legally drive and no rental firm will hand you keys. You can only obtain it in the UK before you fly; it cannot be issued in Japan. Bring your UK licence, the Geneva IDP and your passport as a set. Your licence is good for stays of up to 12 months.
The big upside: you keep left
Japan drives on the left, exactly like the UK. That removes the single biggest hazard British drivers face elsewhere abroad — there is no wrong-side instinct to fight, no roundabout flowing the opposite way. Your muscle memory works. What takes adjustment instead is the signage: major routes carry English, but smaller roads lean on kanji, so an offline map with romanised place names is worth setting up before you go.
Strict alcohol, low limits and costly tolls
The blood-alcohol limit is 0.03, far below the 0.08 of England and Wales, and enforcement is serious — treat driving days as completely dry. Limits are modest: 40 km/h in town, 60 on rural roads and 100 on the expressways, with fixed and mobile speed cameras widespread, so the numbers are enforced. Budget too for expressway tolls, which are among the highest anywhere and add up fast on a long route. Fuel is around $1.35/litre, and the emergency number is 110 for police (119 for fire and ambulance), not 999. A missing required item such as a warning triangle can draw a fine of around JPY 9,000.
