The Japan Automobile Federation (JAF) is one of four certified providers authorized to create an official Japanese translation of your driver's license. The JAF's translation service alone currently costs "only" 6,000 yen. However, you must consider the fact that you can only use the JAF's services if you are physically in Japan. This means you cannot apply for your Japanese driver's license translation during your travel preparations.
So, if you have enough time after arriving in Japan, you can easily apply for your Japanese driver's license translation yourself at the JAF. Simply use their official website: Japan Automobile Federation Driver's License Translation.
Please note that depending on demand, a JAF translation can take at least 5 business days. Don't you have 5 business days after arriving in Japan? Or you don't want to navigate the Japanese website of the Japan Automobile Federation to apply for your JAF translation yourself? Then we at DriveDocs Japan are happy to assist you.
At DriveDocs Japan, you can conveniently apply for your official JAF translation from home – even weeks or months before your departure. Simply upload your driver's license data and travel details, and we'll take care of the rest. You will then either receive a print code by email before your departure (including detailed print instructions) or we will send your driver's license translation conveniently by mail to your home. Personally, we recommend printing your JAF translation yourself at a 7-Eleven. This is significantly cheaper, and you'll likely find yourself in a 7-Eleven sooner or later anyway. Why not combine the useful with the pleasant?
