Convert Foreign License Japan (2026): New Rules + 3‑Month Proof

If you’re trying to convert foreign license Japan (外免切替 / gaimen kirikae) in 2026, most “step-by-step” guides miss the two issues that actually get people rejected at document screening:

• The 3-month proof problem: you must prove you stayed in the license-issuing country for a total of at least 3 months after obtaining the license—and a renewed/reissued card often hides your real first-issue date.
• The appointment problem: reservation systems are now prefecture-specific (web/phone/in-person windows), and popular centers fill instantly.

This 2026-ready checklist focuses on avoiding rejection under the stricter nationwide operation that started October 1, 2025. (keishicho.metro.tokyo.lg.jp)

What Changed on Oct 1, 2025

The rules didn’t just “get stricter”—the entire screening logic changed. Since October 1, 2025, police tightened (1) residence/address verification, (2) the knowledge check, and (3) the skills check for foreign-license conversion. In 2026, this means the bottleneck is often document screening + reservation, not the test itself. (keishicho.metro.tokyo.lg.jp)

1) Residence proof is stricter: juminhyo is now central

For most foreign residents, you’ll be asked for a certified copy of your record from the juminhyo resident registry, and it needs specific items shown (status of residence, period of stay, expiry date, residence card number, etc.). Tokyo also states juminhyo used for these procedures should be issued within 6 months. (keishicho.metro.tokyo.lg.jp)

Practically, this means short-term visitors without resident registration are effectively excluded from conversion in most cases (with limited exceptions like some diplomatic/official cases). If you’re a resident with a residence card, you should plan your city/ward office registration early so you can obtain the right juminhyo. (police.pref.kanagawa.jp)

2) The knowledge check changed: 50 questions, 90% to pass

In Tokyo, the Metropolitan Police Department explains that the “knowledge confirmation” changed from 10 questions to 50 questions, with a pass line of 45/50, and the former illustration-style questions were abolished. Tokyo also notes it is conducted once in the afternoon only. (keishicho.metro.tokyo.lg.jp)

Other prefectures publish similar standards; for example, Kanagawa describes a 50-question true/false format with a 90% pass requirement and lists available languages. Don’t assume your prefecture still runs the “easy 10 questions”—in 2026, you should expect the upgraded version nationwide. (police.pref.kanagawa.jp)

3) The practical/skills check is stricter—and scheduling matters

Tokyo’s official “Required Documents” notes a real-world detail many people learn too late: if you’re required to take a driving skills verification test, it may be scheduled 3–4 months after you book a slot, and your foreign license must still be valid on the day of the skills test. So if your license is expiring soon, renew first (and expect to re-translate if details changed). (keishicho.metro.tokyo.lg.jp)

Multiple prefectures also explicitly state that skills-check scoring and course items were tightened from Oct 1, 2025. Treat this like a real exam, not a formality. (keishicho.metro.tokyo.lg.jp)

Eligibility Checklist to Convert Foreign License Japan: Juminhyo + the 3-Month Proof (Renewed License Problem)

This is where most rejections happen. Your goal is to pass document screening on the first try, because a “come back later” often means you lose your appointment slot and have to rebook from scratch.

A) Juminhyo: how to avoid the “wrong version”

First, you need to be properly resident-registered in Japan so you can obtain a juminhyo. For example, Osaka City explains that foreign residents must complete resident registration at their local ward office within 14 days of moving in, and it lists the residence card and other documents typically required. (city.osaka.lg.jp)

When you request your juminhyo for driver’s license procedures, don’t just ask for “a juminhyo.” In Tokyo’s English “Required Documents,” non-Japanese nationals are told the juminhyo must include the “special notes” (status of residence, period of stay, expiry date, residence card number, etc.), and it should be issued within 6 months (and photocopies are not accepted). (keishicho.metro.tokyo.lg.jp)

What to say at city hall/ward office (simple): “I need a juminhyo for driver’s license procedures. Please include all required items for foreign residents (special notes), and please do not print My Number.” If My Number appears, Tokyo warns you may be asked to black it out. (keishicho.metro.tokyo.lg.jp)

If city hall paperwork feels intimidating, we also keep a plain-English walkthrough in our guide Easy Japanese city hall paperwork in Japan (2026).

B) The “3-month stay after license issuance” requirement (what they actually check)

Japan’s conversion process requires you to prove that after obtaining your foreign license, you stayed in the issuing country/region for a total of 3 months (90 days) or more. Kanagawa states this eligibility requirement directly, and Tokyo’s English documents describe it as “three (3) months or more in aggregate since acquisition.” (police.pref.kanagawa.jp)

Most people try to prove this with passport stamps. But Tokyo explicitly warns that if you used automated immigration gates, you may need to obtain entry/exit records from the license-issuing country/region, and even without eGates you might still be asked for entry/exit records or other documents. (keishicho.metro.tokyo.lg.jp)

C) The renewed/reissued license problem: your card shows only a “renewal date”

This is the #1 silent rejection reason we see among residents. If your license card doesn’t clearly show the original acquisition date (or only shows a recent reissue/renewal date), Tokyo states you must submit a document that verifies the acquisition date/first acquisition date, such as driving records. (keishicho.metro.tokyo.lg.jp)

Workable solutions (bring more than you think you need):

• Driving record / license history from the issuing authority (DMV/transport authority) showing “first issued” and class/category dates.
• Old expired licenses from the same country/region (Tokyo recommends bringing past ones if any).
• Category-specific proof if you’re converting more than one type (e.g., car + motorcycle)—Tokyo notes each license type may need acquisition-date verification.

Tokyo’s country-by-country list even gives examples of what they may request (e.g., “Driver Record,” “Driver History Record,” “Online Driving Record,” etc., depending on the country), and it notes that if passports lack stamps you may need travel-history records. (keishicho.metro.tokyo.lg.jp)

Important: Don’t assume “I’ve driven for years” is enough. The screening desk is checking documentary timelines, and a renewed card that looks “new” can reset their interpretation unless you bring the supporting record. (keishicho.metro.tokyo.lg.jp)

Documents & Translations to Convert Foreign License Japan: JAF Online-Only, Country-Specific Extras, Fees

Document requirements vary by prefecture and issuing country, but the translation workflow is now a universal planning item—because it takes time.

1) JAF driver’s license translation is online-only (plan ahead)

The Japan Automobile Federation (JAF) is one of the main official sources for Japanese translations used for driving license Japan foreigner procedures, and it made a major change: starting April 1, 2025, translation applications are accepted online only (counter/mail stopped). JAF also states translation applications cannot be requested from outside Japan, though a proxy in Japan can apply for you. (jaf.or.jp)

On JAF’s English guidance, the Japanese translation fee is ¥4,000, and JAF explains you can print the translation at convenience stores in Japan using the provided printing method (with a small per-page printing fee). JAF also notes you must have a paper translation—copies, PDFs, and photos are invalid. (english.jaf.or.jp)

Timing: JAF’s FAQ says printing is usually possible about 1–2 weeks after application, and some licenses take longer (2–3 weeks) depending on language/country. Build this into your reservation plan—don’t book a screening date you can’t meet. (english.jaf.or.jp)

If you need help contacting JAF, JAF publishes an international services contact list (including an email for translation inquiries). (english.jaf.or.jp)

2) Translation isn’t “JAF only”: accepted issuers depend on your case

Many prefectures accept Japanese translations issued by an embassy/consulate, JAF, and (for certain countries) other designated organizations. Tokyo’s official English “Required Documents” lists multiple accepted institutions (including embassies/consulates, JAF, and other designated issuers depending on the license). (keishicho.metro.tokyo.lg.jp)

Bottom line: before paying anyone, confirm on your prefecture police site which translations they accept for your issuing country. Do not rely on rental-car company rules for conversion paperwork—they’re different processes.

3) Country-specific extras (and the “29-country exemption”)

Japan has a widely used “exemption” list where knowledge and skills confirmation can be waived (depending on the issuing country/region and, for the U.S., certain states). Tokyo lists 29 countries/regions where knowledge and skills checks are exempt, and Aichi Prefectural Police publishes the same 29-country list for its special foreign-license conversion reservation frame. (keishicho.metro.tokyo.lg.jp)

Tokyo’s published exemption list (29): Iceland, Ireland, United States (Ohio, Oregon, Colorado, Virginia, Hawaii, Maryland, Washington only), United Kingdom, Italy, Australia, Austria, Netherlands, Canada, South Korea, Greece, Switzerland, Sweden, Spain, Slovenia, Czech Republic, Denmark, Germany, New Zealand, Norway, Hungary, Finland, France, Belgium, Poland, Portugal, Monaco, Luxembourg, Taiwan. (keishicho.metro.tokyo.lg.jp)

Even if you’re on the exemption list, you still need to pass document screening (juminhyo, acquisition date proof, and 3-month stay proof). If you’re not on the list, assume you’ll need both the knowledge check and the skills check—and plan multiple visits. (keishicho.metro.tokyo.lg.jp)

4) Fees (example: Tokyo Metropolitan Police Department)

Fees vary by prefecture and license class. In Tokyo, the Metropolitan Police Department lists an application fee of ¥2,500 for an ordinary car license (with different fees for other categories) and a license issuance fee of ¥2,350. Use your prefecture’s site for the authoritative numbers, but Tokyo’s page is a good baseline for budgeting. (keishicho.metro.tokyo.lg.jp)

Booking & Test-Day Survival: Prefecture Differences + IDP Alternatives + LO-PAL Help

In 2026, “how to book” is not a small detail. It’s often the difference between getting your Japanese license this season vs. next season.

1) Prefecture reservation systems: concrete 2026 examples

Always start from your prefecture police page. The same procedure name (外免切替) can mean totally different reservation mechanics depending on where you live.

• Tokyo (Samezu/Fuchu/Koto): Tokyo’s official “convert foreign license” page states the process is reservation-based and provides a WEB reservation link via “Keishicho Administrative Procedure Online” (警視庁行政手続オンライン). It also notes that some categories (e.g., certain diplomatic/official cases) must use phone reservation. (keishicho.metro.tokyo.lg.jp)
• Osaka (Kadoma/Komyoike): Osaka Prefectural Police clearly states reservations are taken by phone only, only during a set day/time window, and that phone support is Japanese only. Osaka also publishes the phone numbers for each test center and notes you must prepare all documents before calling. (police.pref.osaka.lg.jp)
• Kanagawa (Futamatagawa): Kanagawa Prefectural Police states conversion is reservation-based and instructs applicants to come in person to the foreign license counter during a specific time window to secure a reservation date, and it publishes a reservation consultation dial. (police.pref.kanagawa.jp)
• Gunma: Gunma Prefectural Police announced the introduction of online reservation for foreign license conversion (with a published phone number for the general traffic center). (police.pref.gunma.jp)

Tip that actually works: treat booking like buying concert tickets. Prepare your documents first, then attempt booking at the exact opening time your prefecture uses (and if it’s phone-only, be ready to redial aggressively).

2) Test-day survival (knowledge + skills)

Knowledge check: In Tokyo, the Metropolitan Police Department lists 20 languages supported for the foreign-license conversion knowledge test. If you’re relying on a non-Japanese language, confirm which venue/days handle it before you book travel or take time off work. (keishicho.metro.tokyo.lg.jp)

Skills check: Don’t expect same-day driving tests. Tokyo’s official documents warn that skills verification can be scheduled months out, and your foreign license must still be valid on the day you test. If your license expires soon, renew it early (and remember: a renewed license may trigger the need for a new translation). (keishicho.metro.tokyo.lg.jp)

3) International driving permit Japan: useful fallback, but residents must watch the “3-month rule”

If you can’t convert yet, you might consider an international driving permit Japan (IDP)—but only if your IDP is valid for Japan (Geneva Convention format) and you meet the timing rules. Tokyo’s Metropolitan Police Department explains that Japan only accepts IDPs issued by Geneva Convention contracting states in the required format, and you must be within 1 year of issuance and 1 year of landing in Japan. (keishicho.metro.tokyo.lg.jp)

Resident pitfall (the misunderstanding that causes “I thought it reset”): Tokyo police also explains the Road Traffic Act “3-month rule” (Article 107-2). If you are recorded in the Basic Resident Register and you leave Japan, obtain a new IDP, and return within less than 3 months, your return date may not become the new start date—meaning you may not be allowed to drive in Japan under that IDP. (keishicho.metro.tokyo.lg.jp)

Chiba Prefectural Police provides an English explainer that also summarizes the “one year from entry/re-entry” limit and warns mid- to long-term residents about the “Three-Month Rule.” (police.pref.chiba.jp)

4) Alternative to IDP for certain licenses: drive with your license + official Japanese translation

Separate from conversion, Japan allows holders of licenses issued in Switzerland, Germany, France, Belgium, Monaco, or Taiwan to drive in Japan if they carry their license plus an official Japanese translation (from designated issuers such as JAF/embassy, etc.) and meet the time limit (not over 1 year from landing). Tokyo police explains these requirements and lists designated translation issuers. (keishicho.metro.tokyo.lg.jp)

This is often the best short-term solution while you’re still collecting the documents needed to convert (especially acquisition-date proof and 3-month stay proof). But it does not remove the need to convert if you’ll live in Japan long-term.

FAQ (2026)

Q: My license only shows a renewal date. Can I still convert foreign license Japan?
A: Yes, but bring an official document proving your original acquisition/first acquisition date (for example, a driving record or license history from the issuing authority). Tokyo explicitly requests this when the acquisition date isn’t shown on the license card. (keishicho.metro.tokyo.lg.jp)

Q: What counts as proof of the “3 months after obtaining the license” requirement?
A: Commonly passports showing entry/exit stamps are used, but Tokyo warns that if you used automated gates (or if stamps are missing), you may need entry/exit records from the issuing country/region. Your prefecture may request additional documents depending on your situation. (keishicho.metro.tokyo.lg.jp)

Q: Do I have to have a juminhyo to convert?
A: For most foreign residents, yes—Tokyo and other prefectures require a juminhyo that includes the required foreign-resident items (“special notes”) and is issued within a specified recency window. Short-term visitors without resident registration are generally not eligible except limited cases. (keishicho.metro.tokyo.lg.jp)

Q: Is JAF driver’s license translation still available at a counter?
A: No—JAF states that from April 1, 2025, applications are accepted online only, and you can’t request JAF translations from outside Japan (a proxy in Japan can apply). (jaf.or.jp)

Q: I live in Osaka. Can I book online instead of calling?
A: Osaka Prefectural Police states reservation applications are accepted by phone only (not by other methods), and only during designated day/time windows. (police.pref.osaka.lg.jp)
