Driving in Japan: Road Rules and Signs a New Resident Should Know First

Quick answer

Hi, I'm Miya, and I help newcomers settle into life in Japan. If you already hold a licence that's valid here, the driving itself isn't the hard part — a handful of local habits are. You keep left, you come to a genuine full stop before every railway crossing, you learn how two cars pass each other on a street with no centre line, and you look for a paid lot instead of a space at the kerb. Learn those first, confirm the details in the official rulebook or with your local traffic police, and the rest falls into place.

Keeping left, and what it quietly rewires

The first thing to rewire is which side you sit on and which side you drive on. Traffic keeps left, and the driver's seat is on the right, which means most of the car's width sits to your left — the side you have the least feel for. Straight roads are easy. Junctions are where old instincts surface: a left turn keeps you tight to the kerb, while a right turn takes you across oncoming traffic, and that crossing turn is the one newcomers tend to rush.

The other reflex worth unlearning early is what a red light means. It means stop, and it keeps meaning stop even when your turn looks clear and nothing is coming. You wait unless a green arrow or a specific sign at that junction permits the movement, and those arrows are common enough at busy intersections that it pays to look up at the signal head rather than assume from habit.

Give yourself an easy first outing. Pick an early weekend morning, stay on roads you already know as a passenger, and take someone along if you can. The indicator and wiper stalks are often on opposite sides from what you're used to, so you will almost certainly wipe the windscreen at your first turn. Everyone does it. Far better to get that out of your system on a quiet street than in a queue at a busy light.

Narrow streets with no centre line

Step off the main roads and you're on streets that were laid out long before cars were the default. There's no centre line, often no pavement either — just a painted strip along the edge that pedestrians, cyclists, schoolchildren and delivery carts all share with you. Walls and hedges come right up to the road, so your sightlines end at the next corner. The unwritten rule is simple: go slowly enough that you could stop for something you haven't seen yet, because sooner or later you will.

When two cars meet on a street that fits one and a half, nobody wins by pressing forward. One driver backs up or eases into a gap — a driveway, a set-back garage door, a slightly wider stretch — and the other slides past. Whoever is closer to a usable gap generally takes it, mirrors folded in if it's really tight. A raised hand or a quick flash of the hazard lights is the usual thank-you, and it's worth returning every time.

Two more habits pay for themselves here. Use the convex mirrors mounted at blind corners; they're there precisely because you cannot see around the wall. And stop for people waiting to cross at a marked crossing, even when there's no signal and no one behind you is expecting it — that's an obligation on the driver here, not a courtesy, and it's one of the things newcomers most often get wrong.

Railway crossings: a genuine full stop, every time

This is the rule that surprises people most, so I'll be direct about it. At a railway crossing you stop completely before the crossing — wheels stationary, not a slow roll — and check both directions before you go, whether or not the barriers are up and whether or not anything is sounding. Traffic behind you will be doing exactly the same thing, so there's no pressure to keep moving. It feels excessive the first ten times and then it simply becomes what you do.

The second half of the habit matters just as much: before you enter, make sure there is room for your whole car on the far side. Never creep onto the rails behind a queue that hasn't cleared. If you somehow end up stuck on a crossing, the answer is not to sit and wait — the barriers are designed to break, so drive through them, and every crossing has an emergency button near the track that stops approaching trains. Look for it once, on a crossing you use often, so you're not hunting for it under pressure.

Reading signs: shapes, colours, and the little plate underneath

You can get most of the way on shape and colour before you can read a word. The one you'll meet first is the stop sign: a red inverted triangle, usually with white text, and it asks for the same real stop as a railway crossing, behind the white line. Round signs with a red rim generally tell you something is prohibited or restricted, blue round signs generally tell you what you must or may do, and yellow diamonds are warnings about what's coming — a curve, a school, a merge, a slippery stretch.

Rectangles are for information. On ordinary roads the direction boards are typically blue, while expressway signage is green, so the colour alone tells you what kind of road you're being routed onto. Once you learn that pattern, colour is usually enough at speed, which matters when a board slides past in a second. Road markings carry meaning too, especially the lines along the edge that define where pedestrians belong on a street with no pavement.

The detail that catches everyone out is the small supplementary plate under the main sign. That plate is where the exceptions live: the hours a restriction applies, the days it doesn't, which vehicles are exempt. A street that looks permanently closed may only be closed on school mornings, and a street that looks open may be a pedestrian zone at three in the afternoon. When a plate has kanji you can't read, treat the restriction as active and check it later rather than guessing at the kerb. Confirm anything you're unsure of in the current rulebook or with the police — this is general practice, not legal advice.

School zones, drinking, and where the car sleeps

Residential areas near schools are often restricted to through traffic during the morning window on school days, sometimes with a permit system for residents. The restriction is posted rather than obvious, and on those streets you'll be sharing the road with children walking in groups. Even outside restricted hours, treat the whole area as a place to crawl. Your navigation may happily route you through a street you shouldn't be on, so the signs at the entrance outrank the voice in the dashboard.

On alcohol there's no grey area to find, and I'd rather say it plainly than dance around it. The norm among drivers here is simply not to drink at all on a day you'll drive — not one, not with food, not several hours earlier if you're unsure. Responsibility can extend beyond the driver to passengers and to whoever supplied the drink, which is why groups here plan the ride home before the first order: someone stays dry, people take the train, or they use a substitute-driver service that brings your own car home for you.

Parking follows a different logic than you may be used to. Kerbside parking on ordinary streets is broadly not allowed and is actively patrolled, so the space you see is rarely a space you may use. Registering a car generally requires proving you have an off-street place to keep it, which is why street parking never became normal here in the first place. In practice you drive to a paid lot — the small ones lock your wheels with a flap or a gate, and you settle at the machine before you return to the car — and you plan that stop before you set off, not after you arrive.

Before you set off: a connected line in the car

Look back over all of this and notice how much of it now lives on your phone rather than in the glovebox. Navigation and live traffic, checking whether a street is restricted at this hour, finding a lot near where you're going and paying for it, calling roadside assistance if something goes wrong, and telling someone you're running late — every one of those is a phone task, and several of them need a Japanese number to register or to receive a confirmation message. A line with data belongs in the car before you turn the key, not after you've already got lost.

Setting one up is refreshingly simple: you apply online with your residence card, and eSIM-capable phones can often connect the same day, so you're typically up and running in about fifteen minutes. Have a look at our setup guide for eligibility and the step-by-step, and confirm the current terms on the page before you apply. Sort the line, learn the four or five habits above, and driving here stops feeling foreign much faster than you'd expect. I'll be right here to help.
