Stricter Foreign License Conversion from Oct 2025 — And the Overlooked Rule: International Driving Permits Are Only Valid for 1 Year
Foreign License Conversion Gets Stricter from 1 October 2025
Japan has tightened the practical requirements for converting a foreign driver’s license to a Japanese one (commonly known as gaimen kirikae). From 1 October 2025, the process is widely reported to be stricter in areas such as identity/address checks, knowledge testing, and practical driving evaluation. If you rely on driving for work or daily life, it is essential to plan ahead.
The Overlooked Issue: An IDP Is Generally Valid Only for 1 Year from the Date of Landing
Many long-term residents focus on the conversion process but miss a separate rule: driving in Japan with an International Driving Permit (IDP) (and in some cases, certain foreign licenses with required translations) is generally permitted only for up to one year from the date you land in Japan (or until the permit expires, whichever comes first).
For long-term residents, this often means: Year 1 OK, Year 2 not OK
- Year 1: If you meet the conditions, you may be able to drive (and rent a car) using an IDP/eligible foreign license.
- Year 2 and beyond: Once one year has passed from your landing date, you generally cannot legally drive using an IDP/eligible foreign license. This can also affect whether rental car companies will hand over a vehicle.
This is exactly why many people experience a sudden problem in their second year of residence: they can no longer drive even though nothing “feels” different in daily life.
“Leaving Japan and Coming Back” Does Not Always Reset the 1-Year Clock
A common misconception is: “If I leave Japan and re-enter, I can use my IDP again for another year.”
In practice, long-term residents should be cautious. Depending on your status and registration under Japan’s resident system, a short trip abroad (especially a return within a short period) may not be treated as a new “starting date” for calculating the one-year driving period. In other words, do not assume that a brief overseas trip will solve the problem.
Note: exact handling can depend on your circumstances and the relevant guidance applied by the authorities. If driving is essential for your work, confirm the rules directly with the relevant driver’s license center.
Practical Strategy: Avoid a “License Gap”
1) If you will stay in Japan longer than one year, start early
Because the conversion process can take time (appointments, document preparation, test scheduling, re-tests), the safest approach is to start preparing well before you reach the one-year mark.
- Work backward from the date you will need to drive
- Prepare identity/address documents early
- Organize evidence required for eligibility (where applicable)
- Secure proper translations of your license if needed
2) If your job depends on driving, plan with your employer
For roles involving company vehicles, sales visits, site travel, deliveries, or commuting by car, a “license gap” can become an employment risk. Companies hiring foreign residents should incorporate driving eligibility into onboarding and scheduling.
3) Consider alternatives if conversion is not feasible in time
If the conversion pathway is not available or you cannot complete it before the one-year limit, you may need to explore standard licensing routes (driving school, examinations) or operational alternatives (public transport, driver assignment, etc.).
FAQ
Q1. I have a residence card. Can I drive with an IDP beyond one year?
In general, driving with an IDP is limited to one year from your landing date. Long-term residents should not assume that short trips abroad automatically “reset” the one-year clock. Confirm your situation with the appropriate driver’s license center if driving is essential.
Q2. Can I keep renting a car in my second year in Japan?
If the one-year period from your landing date has passed, you generally cannot drive with an IDP/eligible foreign license, which can prevent car rental usage. The practical solution is to obtain a Japanese driver’s license in time.
Q3. What is the biggest risk after the October 2025 tightening?
For many residents, the combination of (i) stricter conversion procedures and (ii) the one-year IDP rule creates delays. That is why early planning is critical.
