Singapore on a Japanese Licence — Same Side, but 4 Demerit Points Per Mistake

Most guides for driving in Singapore open with a warning about switching sides. For Japanese visitors that warning does not apply: Japan and Singapore both drive on the left, so your instincts at junctions, roundabouts and overtaking are already right. What differs is the enforcement, the points and the paperwork.

Same side, so what is different?

The side of the road is identical. The driver sits on the right, you keep left, and roundabouts flow clockwise. Everything else is a rule change: how points work, how tolls are paid, and what happens if you hold a phone. The rest of this page covers those differences in the order they are likely to affect a Japanese visitor.

The permit

Your Japanese licence is valid for visits of up to 12 months. On paperwork the sources differ slightly. Global Affairs Canada says to carry an IDP, and GOV.UK says a 1949 IDP is needed for hiring a car and for stays over 30 days. Japan issues only the 1949 Geneva model, so one document covers both statements. Sort it in Japan before you fly and carry it with the licence and your passport. Check the details against the Driving Permit Checker.

Demerit points, not just fines

A single speeding ticket runs around SGD 150 (about EUR 100) plus 4 demerit points. At 20 km/h over it is still SGD 150 but with 6 points, and past 30 km/h over it goes to SGD 150-1,000 with 8-12 points and a court appearance. Other offences hit harder than their Japanese equivalents:

A phone in hand costs roughly six to eleven times more than the Japanese fine. Estimate other cases on the Speeding Fine Calculator.

Alcohol: higher number, no cushion

Singapore’s blood-alcohol limit reads as 0.08, higher than Japan’s 0.03. It looks lenient, but drink-driving penalties can include jail time, and a number on paper is no safe margin. Treat it as a strict country.

Speeds against Japan

Expressways are the place where Singapore is slower, and the cap is firm. Japanese drivers used to 100 should watch the speedometer on every expressway.

Phones, passengers and the first day

Because a phone in hand brings 12 points at once, mount the phone before you move off and set the route while parked. Brief your passengers too: a driver who is handed a phone to read a message is still the one who pays. Pick up the car in daylight, check that the in-vehicle unit is fitted, and spend the first drive on a quiet route.

ERP and the hire car

Singapore runs Electronic Road Pricing: gantries deduct a toll as you pass during peak hours. Your rental will need a stored-value card in the in-vehicle unit; ask the desk to confirm it is topped up, since an unpaid gantry turns into an administrative fee later.

Emergency numbers

Do not rely on Japan’s 110 and 119. In Singapore the police number is 999 and ambulance and fire are 995. Equipment rules are light: no fire extinguisher, first-aid kit or reflective vest is required, and a warning triangle is only recommended, whereas Japan lists the triangle as required. Roads are excellent and clearly signed, so once the points discipline and ERP routine click, Singapore is one of the easiest places a Japanese driver can rent a car. Read the wider rules on our Singapore driving guide before collecting the car.
