Route guide
San Francisco → Osaka
Osaka runs on Japan’s quarantine-exemption system, so the rabies titer test has to be drawn and cleared by an approved lab at least 180 days before arrival — the reason this route needs a 210-day runway. United and Delta both fly the corridor, accepting only small pets in the cabin and routing anything larger as manifest cargo through their live-animal desks. Advance notification to Japan’s Animal Quarantine Service is also required ahead of the flight. Handled on this timeline, pets clear at Kansai without extended quarantine.
What this route involves
Flying from San Francisco to Osaka means clearing Japan entry rules on arrival and meeting your airline’s own conditions on departure. Below are both, plus the order to do them in.
Leaving United States
Requirements differ sharply depending on where your dog has been in the previous six months. Cats face no federal rabies requirement, though individual states may add their own.
See full entry rulesEntering Japan
Japan runs one of the most procedure-heavy entry processes in the world — but there is no long quarantine if you follow every step in order. The critical one is the rabies antibody (titer) test, which starts a waiting period of up to 180 days before your pet can enter.

Your chronological checklist
Work backwards from your travel date. Start the earliest step first — some cannot be rushed.
- 1 Implant an ISO 11784/11785 microchip211 days before travel
It has to come first: every later certificate references this number, and a rabies shot given before the chip usually does not count.
- 2 Rabies vaccination210 days before travel
Must be given after the microchip and be valid on the day you travel. Most destinations also require a minimum of 21 days between the shot and entry.
- 3 Rabies titer (blood antibody) test180 days before travel
Blood is drawn at least 30 days after vaccination and sent to an approved lab. The waiting period that follows is the single longest part of the trip.
- 4 Apply for the import permit30 days before travel
Government approval takes weeks and often fixes the exact dates of every other step, so apply as early as the authority allows.
- 5 Book the flight and reserve the pet slot30 days before travel
Airlines cap how many animals travel per flight. The pet slot runs out well before the seats do.
- 6 Health certificate and official endorsement2 days before travel
Issued by an accredited vet close to departure, then endorsed by your government authority. This endorsement cannot be done at the airport.
- 7 Travel dayTravel day
Carry the originals plus copies of everything, arrive early, and keep the crate documents attached to the crate.
