How to Convert Your Driver’s License in Shizuoka Prefecture (外免切替）

If you’re living in Shizuoka and already have a valid foreign driver’s license, you can legally drive in Japan by converting it into a Japanese license through a process known as “Gaimen Kirikae” (外免切替).
This guide will walk you through everything you need to know, from the required documents to where you need to go in Shizuoka to complete the process. Who knows, after reading the article, you may find that the process isn’t so daunting after all!

What Is Gaimen Kirikae?

Gaimen Kirikae (外免切替) is the official process for converting a foreign driver’s license into a Japanese one.
If you’ve lived in Japan for more than a year or your International Driving Permit (IDP) has expired, you’ll need to complete this conversion before you can legally drive again.

The process usually includes:

• Document screening
  
• A written test
  
• A driving (skills) test
  

The specific requirements depend on your country of issue, but it’s best to prepare for both the knowledge and practical exams in advance.

Where to Apply in Shizuoka

In Shizuoka Prefecture, foreign license conversions are handled by the prefectural Driver’s License Centers (運転免許センター).
There are three main centers under the Shizuoka Prefectural Police, and which one you go to depends on your registered address:

Documents You Will Need

Before booking your screening appointment, prepare the following items:

• Your valid foreign driver’s license
  
• Official Japanese translation of your license (issued by JAF or Ziplus)
  
• Residence card (在留カード)
  
• Passport (old and current, to verify your stay)
  
• My Number card or Resident Record (住民票)
  
• 1 photo (3×2.4 cm, plain background)
  

We can provide an official translation within 1 day (or in just a few hours with our Express option), which is accepted at all Shizuoka license centers.

The Written Test in Shizuoka

The written test in Shizuoka is available in English and other languages.
It consists of 50 multiple-choice questions, and you need to score 45 or more to pass.
Although the questions may seem simple, the wording can be tricky, and many applicants fail because they’re unfamiliar with Japan-specific traffic rules and customs. That said, it is by no means insurmountable, and with some proper preparation, you will pass without issue.

Tip: Study beforehand using our test-prep materials, which includes textbooks, videos, and an interactive app with practice questions tailored to the 2025 exam format.

 The Driving Test in Shizuoka

The practical driving test is conducted on a closed course at the license center.
Even experienced drivers often fail their first attempt because the test focuses on Japanese driving etiquette and precision, such as:

• Proper mirror and shoulder checks
  
• Using the full width of the lane when turning
  
• Maintaining smooth, predictable control
  
• Correct use of turn signals and stop lines
  

The course layout differs slightly by center, but preparation lessons can help you learn what the examiner will be looking for.

How Long Does the Process Take?

From the first document screening to receiving your new Japanese license, the process typically takes 2–4 months, depending on appointment availability and whether you pass on the first try.
To save time, make sure all your documents are correct and translated before your screening date.
