Booking a Foreign License Conversion at Konosu (Saitama)

埼玉県警察 ／ 外免切替 書類審査（1回目・初めて）

Last updated: September 23, 2026

If you are converting a foreign license to a Japanese one in Saitama, you book your appointment at the Konosu license center. This page walks you through how to reserve a slot and what to do when you cannot find one.

Konosu accepts a fixed number of people per day for conversions, and slots disappear quickly once they go live. Many people end up refreshing the booking page over and over.

How to book

1. Open the Saitama Police booking system (e-TUMO) and book the document review (書類審査) first.
2. Find the row for your category (first time, 2nd+ time, or test-exempt country), pick an open date, and fill in your details.
3. Bring the reception number (受付番号) from the confirmation email to your document review.
4. After the document review, book the knowledge test (知識確認) separately if it applies to you. You can pick the test language.

What to prepare

• Residence card
• Passport (showing your entry and exit history)
• Your foreign driver's license
• A Japanese translation of the license (issued by JAF, your embassy, or similar)
• Certificate of residence (juminhyo)
• ID photo

Requirements vary by category and situation. Always confirm the current document list on the Saitama Police website.

Tips for getting a slot

• Test-exempt countries skip the knowledge test. Check which category your country falls into first.
• Gather your documents in advance so you are ready the moment a slot comes up.
• Slots are sometimes added at set times, so checking often helps.

Frequently asked questions

Do I need to take the knowledge test?

Unless your country is test-exempt, you book and take a knowledge test separately after the document review. Confirm the details on the official site.

I can never get a slot.

There are very few slots, so you need to catch them right after they open. Yoyatto emails you the moment one appears.

How far ahead can I book?

It depends on what has been released. Near-term slots fill fast, so checking early is best.
