Introduction
Japan is one of the destinations Thai pet owners most often want to bring their pets to — and it's also one of the strictest. Japan's Animal Quarantine Service (AQS) requires pets from rabies-endemic countries (which includes Thailand) to go through a lengthy process. Done right, your pet clears Narita customs within hours. Done wrong, your pet can be held at the airport for up to 180 days at the owner's expense.
The 5 conditions you can't skip
1. ISO microchip first
An ISO 11784/11785 chip must be implanted before any rabies vaccine. Vaccines given before the chip don't count — full restart.
2. Two rabies vaccines
Japan requires two rabies vaccines on record before the titer can be drawn (most other countries accept one). The interval between vaccines should follow the vaccine manufacturer's protocol.
3. FAVN titer at an AQS-approved lab
The rabies titer test must come back at ≥ 0.5 IU/mL from a lab approved by Japan's AQS. Common approved labs include KSU in the US, IZSVe in Italy, and ANSES in France. Thai-based labs aren't on the AQS approval list.
4. The 180-day wait — the rule with no exception
The clock starts on the date the FAVN blood sample arrives at the lab (not the draw date). From that day, your pet must wait at least 180 days before entering Japan. This is the longest step in the timeline and isn't reducible.
5. Advance Notification to AQS
You must file the Advance Notification with AQS at least 40 days before the flight. The form includes the chip number, vaccine dates, titer result, AHC details, and arrival airport.
Total timeline
| Step | Time needed |
|---|---|
| Microchip + 1st rabies vaccine | Day 0 |
| 2nd rabies vaccine (per manufacturer interval) | ~1 month |
| FAVN blood draw → sample arrives at lab | +30 days minimum after 2nd vaccine |
| 180-day waiting period | +180 days from sample arrival |
| Advance Notification to AQS | ≥ 40 days before flight |
| Total minimum | ~7 months from start to flight |
Convey team's note: If the 180-day wait isn't met (even by one day), Japan will hold your pet at the airport quarantine until the period is complete. The owner pays the full cost. This is why we start every Japan case with the FAVN sample-arrival date as the central time marker.
