Driving in the UK on a Japanese Licence — Same Left Side, Roundabouts & mph

Japanese drivers land in Britain with a head start most foreign visitors would envy. Japan and the UK both drive on the left, so there is no side to relearn — the wheel is on the right where you expect it, the gearstick is under your left hand, and your road instincts already aim the correct way. The exhausting part of driving abroad simply does not apply here.

Documents are straightforward. Your Japanese licence is valid for stays of up to 12 months. An International Driving Permit is not legally compulsory, but rental companies and police like to see one as a recognised translation of your licence — get one before you fly and carry it with your licence and passport. The Driving Permit Checker confirms what your trip needs.

What actually takes adjusting is the roundabout. Britain runs on them, often two or three lanes wide, far more common than in Japan and governed by a give-way-to-the-right rule that rewards decisiveness. Read your exit early, signal, hold your lane. The other unfamiliar feature is narrow rural lanes with passing places — single-track roads where you reverse into a bay to let oncoming cars through. They are slower and tighter than anything in urban Japan.

Speeds are posted in miles per hour: 30 mph (48 km/h) in towns, 60 mph (96 km/h) on rural roads, 70 mph (112 km/h) on motorways. That motorway figure is faster than the 100 km/h you are used to at home, so there is more pace on the big roads — stay within your comfort zone. Cameras are everywhere, and 10 mph over the limit costs a GBP 100 fine plus 3 penalty points. Run the numbers with the Speeding Fine Calculator.

The drink-drive limit is 0.08 BAC in England, Wales and Northern Ireland — looser than Japan’s strict 0.03 — but Scotland drops to 0.05, so the rule is not uniform across the country. The simplest policy is nothing before you drive.

Fuel costs roughly $1.85 a litre, cheapest at supermarket forecourts, and the emergency number is 999 (112 also works). Read our full United Kingdom driving guide before collecting your car.
