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.

StepTime needed
Microchip + 1st rabies vaccineDay 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.

FAQ

Q: Why does Japan require two rabies vaccines?
A: Japan is rabies-free and considers the second dose stronger evidence of sustained immunity. Most other countries accept one valid vaccine — Japan's requirement is its own.
Q: Can I have the FAVN done at a Thai lab to save time?
A: No. AQS only accepts results from labs on its approved list, none of which are in Thailand. The sample must be sent to KSU (US), IZSVe (Italy), or another AQS-approved lab.
Q: Does the 180 days count from blood draw or sample arrival at lab?
A: From the date the sample arrives at the lab — that's the official starting point. The blood draw might be a day or two earlier.
