1949 vs 1968 Convention: Which IDP Works in Japan?
Short answer: for driving in Japan, the relevant standard for the permit route is the 1949 Geneva Convention IDP format. A 1968 Vienna Convention permit alone may not satisfy legal requirements for your specific use case, including street kart tours.
Many travelers buy an "international driving permit" online without checking which treaty it actually references. The two conventions are not interchangeable in Japan, and showing up with the wrong one is one of the most common reasons for rejected check-in.
A 1968 permit may be invalid for your case
Verify the treaty format printed on your permit before booking. Similar appearance does not mean legal equivalence.
What the Two Conventions Actually Mean
The 1949 Geneva Convention on Road Traffic and the 1968 Vienna Convention on Road Traffic are two separate international treaties that establish different frameworks for International Driving Permits. Japan primarily recognizes the 1949 Geneva Convention format for the permit route. Many other countries (particularly in Europe) have adopted the 1968 Vienna Convention. This treaty gap is the root cause of confusion.
For your permit to be valid in Japan, the wording "1949 Geneva Convention" should appear on the document itself. If your permit only references the 1968 Vienna Convention, it is likely not accepted for the permit-based driving path in Japan — including for street karting.
Fast Side-by-Side Comparison
1949 Geneva Convention (Accepted)
Physical booklet format. Issued by authorized organizations in your home country (AAA/AATA in the U.S., Post Office in the U.K., CAA in Canada). Must be original, not digital.
1968 Vienna Convention (Not Accepted Alone)
Digital-only delivery common. Often sold by unofficial online resellers. May look similar but lacks the treaty basis accepted in Japan for the permit route.
How Each Country Is Affected
Your home country determines which convention your local issuer follows. Knowing this in advance lets you confirm whether your permit is the right type before you spend money.
United States
AAA and AATA issue 1949 Geneva Convention IDPs. This is the correct format for Japan.
United Kingdom
Post Office issues 1949 format. Confirm the booklet before leaving the counter.
Canada, Australia, New Zealand
National motoring organizations issue 1949 format. Request the physical booklet at least 2 weeks before your trip.
Taiwan, Germany, Switzerland, France, etc.
These countries typically use the JAF translation route instead of IDP. You do not need an IDP at all — use your license + JAF translation + passport.
What If My Country Only Issues 1968 Permits?
If your home country only issues 1968 Vienna Convention IDPs and you are not eligible for any alternative route (JAF translation, SOFA, or Japanese license), you may not have a legal path to drive in Japan as a tourist. This is an unfortunate but real limitation. Always use the eligibility questionnaire before booking non-refundable travel.
Some travelers in this situation have successfully driven in Japan by obtaining a Japanese driver's license through the license conversion process, but this requires residency and is not practical for short-term visitors.
The "Universal Permit" Scam
Websites that promise a "universal international driving permit valid in all countries" are almost always scams. These documents typically cite neither the 1949 nor 1968 convention, lack verifiable issuing authority, and are delivered as PDFs or digital cards. No such universal permit exists under international law.
Pre-Trip Verification Checklist
Read the treaty name printed on your permit — is it "1949 Geneva Convention"?
Is the document a physical booklet you can hold, not a PDF or app?
Was it issued by an official organization in your country (AAA, CAA, Post Office, etc.)?
Do the names on your permit and passport match exactly?
Is your passport valid for the entire duration of your stay?
Still Unsure? Use the Questionnaire
The eligibility checker walks you through your specific country and driver profile to confirm your exact legal path. It takes 30 seconds and removes all guesswork.
