Do You Need an IDP to Drive in Japan from the US?
Japan is one of the strictest countries in the world about International Driving Permits. If you plan to drive in Japan with a US driver's license, you must carry a valid IDP. Without one, you cannot legally drive, and rental car companies will not hand over keys.
What the law requires
Japan is a signatory to the 1949 Geneva Convention, which means it accepts IDPs issued under that treaty. The IDP issued by AAA in the United States is the correct document. The 1968 Vienna Convention IDP is **not** valid in Japan, so EU-issued permits often won't work either.
You must carry three documents at all times when driving:
- Your valid US driver's license
- Your AAA-issued IDP
- Your passport
Enforcement is real
Unlike some countries where IDP requirements are loosely enforced, Japan actively checks. Police perform random license checks, especially in tourist-heavy areas like Kyoto, Hokkaido, and Okinawa. The penalty for driving without a valid IDP is up to ¥300,000 (~$2,000 USD) and your rental car will be impounded.
Rental car insurance will also be voided if you crash without a valid IDP, leaving you personally liable for damages.
How to get one before your trip
The IDP is valid for one year. You need it before you leave the US — Japan does not issue them locally to tourists. Three options:
1. **In-person at AAA** — fastest, ~$20, walk-in. Check that the AAA branch plan to visit does IDPs.
2. **By mail to AAA** — 4-6 weeks processing
3. **Through Fast IDP** — we go to AAA on your behalf and overnight ship it to you, including international shipping if you're already abroad
