The Short Answer

It depends on which international treaty your country signed:

Why the Confusion Exists

There are two international treaties governing driving abroad:

  1. 1949 Geneva Convention on Road Traffic — The older treaty. Japan is a signatory. IDPs issued under this convention are valid in Japan.
  2. 1968 Vienna Convention on Road Traffic — The newer treaty. Japan has not signed this one. IDPs issued under this convention are not valid in Japan.

The problem: many countries (including Germany, France, and Switzerland) only issue IDPs under the Vienna Convention. When you get an IDP from ADAC in Germany or from the Strassenverkehrsamt in Switzerland, it's a Vienna Convention IDP — which Japan doesn't recognize.

Japan's solution: Article 107-2 of the Road Traffic Act allows drivers from specific countries to use an official Japanese translation of their license instead. This translation must be in JAF format — the format used by the Japan Automobile Federation.

Common Mistakes to Avoid

❌ Mistake 1: "I have an IDP, I'm fine"

This is the #1 mistake. If you're from Switzerland, Germany, France, Belgium, Monaco, or Taiwan, your IDP is not valid in Japan. Many tourists only discover this at the rental car counter — ruining their road trip plans.

❌ Mistake 2: "I'll just get the translation when I arrive"

While you can get a JAF translation in Japan, the process takes time and requires navigating a Japanese website. If you plan to rent a car on day one, you need the translation ready.

❌ Mistake 3: "I'll show a digital copy on my phone"

The translation must be printed on A4 paper. Digital copies are not accepted by rental car companies or police. Always print your translation before your trip.

❌ Mistake 4: "An IDP from my embassy will work"

Some embassies issue IDPs, but these may be under the Vienna Convention. Only a Geneva Convention IDP or an official JAF-format translation is accepted in Japan.

FAQ

Q: I have both a Geneva and Vienna Convention IDP. Can I use either?
A: You need the Geneva Convention IDP specifically. Check which convention is printed on your IDP — it's usually noted on the cover or first page.

Q: My country signed both conventions. What do I need?
A: If your country signed the Geneva Convention, an IDP is sufficient. Check with your automobile association which convention your IDP is issued under.

Q: Can I use a notarized translation instead of a JAF translation?
A: No. Japan only accepts translations in the official JAF format. Private translations, even notarized ones, are not legally valid for driving in Japan.

Q: I'm from Germany. Should I use ADAC or JDLTC?
A: Both are valid options. ADAC is cheaper (€65-70) but requires mailing your original license to Munich and takes 10+ business days. JDLTC is fully online with photo upload and costs ¥9,800.
