Driving in Japan as a Foreigner: License Conversion, IDP Rules and Traffic Basics (2026)

Few countries make it as easy to live without a car as Japan. In Tokyo, Osaka or Fukuoka the rail network covers almost everything, and a parking space in the city center can cost more per month than the car itself. Move an hour outside those networks — rural Hokkaido, Nagano, Shimane, the outer suburbs of any prefecture — and it flips: a car is what makes an ordinary life possible.

What catches foreigners out is not the driving. It is the paperwork. Japan has three separate legal routes for a foreigner behind the wheel, each with different eligibility rules, and the most common one was tightened on 1 October 2025. The short version:

This guide covers all three routes, what conversion involves after the 2025 changes, and the traffic rules that trip up drivers who have been driving for years at home.

The Three-Month Rule Underneath Everything

Before the routes themselves, understand the rule that sits under all three: you may only drive in Japan on a foreign license or permit if you obtained that license and then stayed in the issuing country for a total of at least three months (Road Traffic Act, Article 107-2). The same condition decides whether you are allowed to convert a foreign license at all.

The rule exists to stop license shopping — buying a license in a country with a trivial test and then using it here. How is it proven? With passport stamps, entry and exit records, or documents showing where you actually lived. A license from a country you visited for two weeks will not work.

Two details matter once you already live in Japan:

• Leave and return within three months and your original landing date still counts. Re-entering does not restart your one-year clock.
• Stay outside Japan for three months or more and return, and the new landing date restarts the clock. A fresh IDP picked up during a short trip home is still unusable if that trip was under three months.

Route 1: International Driving Permit

Only one convention counts

Japan recognizes International Driving Permits issued under the 1949 Geneva Convention, in the Geneva format. A permit issued under the 1966 Vienna Convention is not valid here, even if the issuing country is also a Geneva party. That single fact explains most of the contradictory advice online.

Fifteen Geneva parties do not issue Geneva-format IDPs at all, so an IDP from any of them cannot be used in Japan: Albania, Serbia, Monaco, Ghana, France, Montenegro, Cuba, Bulgaria, Liechtenstein, Côte d'Ivoire, Belgium, Rwanda, Zimbabwe, Botswana and Russia. France, Belgium and Monaco are not a problem in practice, because their national licenses are accepted with a translation (see Route 2).

How long your permit works

Two clocks run at once and the earlier one wins:

• one year from the date the permit was issued
• one year from the date you landed in Japan

What to carry

All three documents: your IDP, your original home license, and your passport. An IDP is a translation of a license, not a license in its own right — without the underlying card it means nothing, and police will ask for both.

Route 2: Licenses Japan Accepts With a Translation

A handful of countries and regions have licensing systems close enough to Japan's that no Japanese test is required. Six qualify: Switzerland, Germany, France, Belgium, Monaco and Taiwan.

If you hold a license from one of them and are within one year of your last landing in Japan, you can drive on that license plus an official Japanese translation. That is the whole requirement — no IDP, no test, no conversion.

The translation has to come from a designated body:

• the authority that issued your license, or that country's embassy or consulate in Japan
• the Japan Automobile Federation (JAF)
• the Taiwan-Japan Relations Association, or Zipras, for Taiwanese licenses
• the German Automobile Club (ADAC) for German licenses
• the Japan Inbound Driver Support Association

Translations you make yourself, or buy from an ordinary translation agency, are not accepted.

Route 3: Converting Your License (外国免許切替)

Everyone else — American, British, Australian, Canadian, Korean, Brazilian, Indian, Filipino and most other license holders — needs a Japanese license once Japan becomes home. The process is called 外国免許切替 (gaimen kirikae), and it is done at your prefectural driving license center, not at city hall.

What changed on 1 October 2025

The Road Traffic Act Enforcement Regulations were amended, and three things got noticeably harder.

The knowledge check. Illustration questions were scrapped. The paper went from 10 questions to 50, and the pass mark from 7 out of 10 to 45 out of 50. It is held once, in the afternoon.

The skill check. New tasks were added, including handling pedestrian crossings, and the marking criteria were made stricter. A lot of people who would have passed in September 2025 now fail.

The documents. Foreign residents must now submit a copy of their 住民票 (certificate of residence) showing the foreign-resident items — nationality, residence status, period of stay, Residence Card number and so on — issued within the past six months.

Step 1: Book before you turn up

Conversion is by appointment, and the skill check cannot be taken on the day you submit your documents. In Tokyo, reception runs on weekdays from 8:30 to 15:00, closed between 11:00 and 13:00, and the centers shut on weekends, public holidays and from 29 December to 3 January. Book online if you have stayed in the issuing country for three months or more; some applicants book by phone instead. Other prefectures run their own hours and booking systems, so check your prefectural police website before asking for a day off work.

Step 2: Documents to bring

• your valid foreign license — the original, never a copy
• the official Japanese translation
• your passport, including the pages showing your entries and exits
• your Residence Card, or Special Permanent Resident Certificate
• a 住民票 copy with the foreign-resident items, issued within the last six months
• a photo, if your prefecture requests one
• any extra evidence of your stay in the issuing country, if your passport does not show it

Step 3: Prove the three-month stay

This is where applications are refused on paperwork rather than on driving. If your license was issued shortly before you left — a student who passed the test two weeks before moving to Japan, or someone who picked up a license through a third country — you need documents that prove residence: entry and exit stamps, an old residence permit, tax or employment records, school transcripts. Without three months, the conversion is refused and no test is offered.

Step 4: The knowledge check (知識確認)

Fifty questions, 45 correct to pass. In Tokyo the conversion questions are available in 20 languages, including English, Chinese, Korean, Portuguese, Vietnamese, Tagalog, Nepali, Spanish, Russian, Thai and Indonesian; Kanagawa offers 21. Other prefectures offer fewer, sometimes only Japanese — check before booking.

Who skips the tests entirely

Applicants whose licence comes from one of 29 designated countries and regions are exempt from both the knowledge and skill checks. The list covers most of Europe, Korea, Taiwan, Australia, Canada, New Zealand, the UK, and a few US states (Ohio, Oregon, Colorado, Virginia, Hawaii, Maryland and Washington; Indiana is exempt from the skill check only). If you are from one of them, the visit is paperwork, an eyesight check and a fee — but the three-month stay rule and the 住民票 still apply.

Step 5: The skill check (技能確認)

A course test, not a road test. This is the stage people fail, often more than once. Pass rates collapsed after the October 2025 changes — police figures reported in the Japanese press put the knowledge check at around 43% and the skill check at around 13%, down from 93% and 30% before. What examiners mark:

• driving position and lane discipline
• complete stops before stop lines
• mirror checks and shoulder checks that are visible to the examiner
• signal timing
• the S-curve and crank (narrow right-angle) sections, where used
• pedestrian crossings, added to the criteria in October 2025

If your center allows it, one or two lessons on the test course with a local driving school is the most reliable money you will spend. Driving schools in Japan teach the test's choreography, not just driving.

Fees

In Tokyo, converting an ordinary license costs a ¥2,500 application fee plus a ¥2,350 issuance fee — roughly ¥4,850 before translation, transport and any lessons. Mopeds are ¥1,600, large and medium licenses ¥3,900. Fees differ slightly by prefecture, and every return visit costs you another day.

The translation is the expensive part. JAF charges ¥6,600 including tax for a translation used in a conversion application (raised from 1 July 2026), and ¥6,000 for one used only to drive on a licence from the six designated countries or regions. Translations from the issuing authority or its embassy are usually free, so ask there first.

Traffic Rules That Catch Foreign Drivers Out

You drive on the left

Obvious, and still the thing people get wrong first. It changes lane positioning, turning, mirror habits and where the driver sits. If you come from a country that drives on the right, expect the indicator and wiper stalks to feel wrong for the first few trips, and expect to drift toward the curb until your positioning recalibrates.

No left turn on red

In countries where turning left on red after a stop is legal, that habit is dangerous here: turning left on red is prohibited in Japan unless a sign or arrow specifically allows it.

Alcohol

The limit is a breath alcohol level of 0.15 mg per liter — for many adults one drink or less. Penalties start at a fine and climb quickly: 酒気帯び (over the limit) carries up to three years' imprisonment or a ¥500,000 fine, and 酒酔い (visibly drunk) up to five years or ¥1,000,000, with licence revocation and disqualification periods attached. Since 21 July 2026 the law also sets a numeric threshold for 酒酔い of 0.5 mg per liter of breath.

The consequences extend past the driver: passengers who knowingly ride with a drunk driver, and people who supplied the alcohol, can be prosecuted as well. If you have had a drink, the answer is a taxi, a train or a designated driver.

Speed limits

Posted limits are low by international standards and are enforced. The statutory limit is 60 km/h on ordinary roads unless a sign says otherwise, 40–50 km/h on many urban streets, 100 km/h on expressways, with 110 km/h and 120 km/h sections on parts of the Shin-Tomei and a few other expressways. Local streets are narrow and pedestrians appear from behind parked cars, which is why the limits are where they are. Follow the signs rather than your instincts from home.

Parking

Street parking is far more restricted than most newcomers expect, and an empty kerb is rarely a legal space. Coin parking (コインパーキング) is everywhere in cities and costs a few hundred yen per hour in the center; malls, supermarkets and stations often have their own lots with validation. Leaving a car on the street overnight in a city usually ends in a fine or a tow.

Expressways, ETC Cards and Rest Stops

Expressways are toll roads, and most Japanese drivers pay with an ETC card slotted into a reader in the car. Rental companies offer ETC cards as an add-on, and without one you drive through the cash lanes and pay more. Some holiday discount schemes are ETC-only, so if you are planning long drives, ask for the card.

Japanese rest stops are a genuine feature of travel here. Service areas (SA) and parking areas (PA) run from simple toilets-and-vending-machine stops to full food courts with regional specialties. On a long drive they are worth building into the schedule rather than treating as emergencies.

Car Sharing and Ownership

Car sharing for occasional drivers

If you live in a city and drive a few times a month, car sharing beats owning. Times Car and Orix CarShare are the two big networks, both with English-language apps, and both bill by time and distance from a station near you. Overnight and long-distance rates are higher, so read the plan before a weekend trip: a two-day rental from a conventional rental company is often cheaper than car sharing for the same trip.

What owning a car actually requires

Two requirements surprise new residents:

• Proof of a parking space. In most cities you cannot register a car without a 車庫証明 (certificate of storage place) showing an off-street space near your registered address. This is checked by the police before registration.
• Two kinds of insurance. 自賠責 (compulsory liability cover) is legally required and pays only toward injury compensation, with low caps. Everyone with any sense adds 任意保険 (voluntary insurance) for vehicle damage and higher liability limits. New drivers with no Japanese claims history pay more.

On top of that: annual road tax, compulsory vehicle inspections (車検) roughly every two years, and parking costs that in central Tokyo can dwarf everything else.

Final Takeaway

Three rules cover most of what foreigners get wrong about driving in Japan:

• if you are driving on a foreign license or permit, your one-year window runs from the date you landed in Japan, not from when you decided to start driving
• to use or convert a foreign license you must have spent three months in the country that issued it after passing the test
• conversion now means a 50-question knowledge check and a stricter course test, so start early rather than the month before you need a car

Decide which route applies to you before you arrive if you can. Visitors should check that their permit is Geneva format — not Vienna — and residents should book the conversion appointment as soon as their address and Residence Card are in order, because the paperwork stage, not the driving, is where most applications stall.
