Driving in Japan: converting your foreign licence (after the 2025 changes)

How long an international permit lasts, who can convert a foreign licence, the three-month rule, the documents, and what the knowledge and driving tests are like since the rules tightened in October 2025.

Driving on an international permit

An International Driving Permit from a Geneva Convention country lets you drive in Japan for up to one year from the day you arrive, as long as the permit itself is valid. Some countries' own licences work with an official Japanese translation instead.

The trap: if you live here, leaving Japan and coming back doesn't reset the year unless you were away for three months or more. Once you're a resident, plan to convert.

What to bring

The knowledge and driving tests

Holders of licences from a list of about 29 countries and regions skip both tests and only have their documents and eyesight checked. Everyone else takes:

Many people fail the driving test the first time. A lesson or two at a driving school's practice course, or with someone who passed recently, is often the cheapest way to pass sooner.

The day itself

  1. 1Check your prefecture's licence centre: many need a booking for the document check, and some only handle certain countries.
  2. 2Go with every document. The document check can take hours.
  3. 3Take the knowledge test (if you need to). If you pass, book the driving test.
  4. 4Pass the driving test, then the licence is issued the same day.
