TLDR: Japan does not quarantine every pet that arrives. Dogs and cats that complete all requirements correctly are inspected on arrival and typically released within a few hours. The 180-day detention quarantine is the penalty for arriving without meeting the requirements, not a standard step in the process. The 180-day waiting period happens before travel in the exporting country, not after arrival in Japan.
Japan does not require a 180-day quarantine for every pet. The 180-day period is a mandatory waiting period that happens before your pet travels, not after arrival. If your pet completes all the required steps correctly and in the right order, the quarantine inspection on arrival takes less than 12 hours. The 180-day detention quarantine is the penalty for arriving without meeting the requirements. Here is how the two scenarios differ and what each one involves. For a full overview of all Japan import requirements, see our Japan pet import guide.
Dogs and cats that arrive in Japan with all requirements completed and all documents in order are inspected by the Animal Quarantine Service at the port of entry. If no problems are found with the documents or the pet's health condition, an Import Quarantine Certificate is issued and the pet is released. The inspection takes less than 12 hours and is typically completed within a few hours.
For compliant arrival, the following must all be in place before boarding:
If every one of these is confirmed, your pet clears in hours, not months.
If any requirement is not met on arrival, your pet will be placed in detention quarantine at an AQS facility for the period necessary to make up the deficiency, up to a maximum of 180 days. Depending on the results of the import inspection, your pet may not be permitted to enter Japan at all.
The most common triggers for detention quarantine are document deficiencies, a waiting period that has not reached 180 days, and a microchip number that does not match the certificates. Any single deficiency is enough to trigger detention.
All costs during detention quarantine are the importer's responsibility. This includes transport from the port of entry to the detention facility, daily boarding and feeding, lighting, heating, water, veterinary visits if needed, and any restoration costs. The importer is also responsible for arranging and funding care during the quarantine period. Caretaker companies are stationed at Narita, Haneda Airport, and Kansai Airport branches for owners who need to arrange feeding and care on their behalf.
During detention, your pet cannot leave the facility under any circumstances except to be returned to the exporting country. Visits are permitted but visiting hours and the number of visitors are restricted. If symptoms of rabies or, for dogs, leptospirosis are observed during detention, the quarantine period may be extended and additional examinations conducted.
The 180-day waiting period is not a quarantine in Japan. It is a mandatory holding period in the exporting country, in this case the United States, that begins on the date of the rabies antibody blood draw. Day 0 is the blood draw date. Your pet must remain outside Japan for at least 180 days from that date before it is eligible to enter.
If your pet arrives before the 180 days are complete, it will be held in detention quarantine at an AQS facility for the remaining days. This is entirely preventable by completing the waiting period before travel.
The titer result that comes from the blood draw is valid for 2 years from the blood draw date, provided the vaccine's effective period remains continuous throughout. If the vaccine's effective period lapses at any point during the 180-day wait, any new vaccination is classified as a primary vaccination, not a booster. This restarts the titer requirement and the full 180-day wait from zero.
If you have not yet begun the Japan import requirements and have a fixed travel date, you have two options: start the requirements immediately and move before your pet, or adjust your travel date to allow enough time to complete the process.
The minimum timeline from the first step to compliant arrival is approximately six months from the blood draw date, and longer when you account for the microchipping, two vaccinations with a 30-day gap between them, and the blood draw itself. Most moves take seven to eight months from start to finish.
Many pet owners move to Japan first and have their pet follow once all requirements are complete. This is a practical option that avoids the stress of rushing the process and the cost of detention quarantine if something goes wrong at arrival.

No. Dogs and cats that arrive with all requirements met are inspected on arrival and typically released within a few hours. The 180-day detention quarantine only applies to pets that arrive without meeting the import requirements.
The 180-day wait is a mandatory holding period in the exporting country before your pet travels. It begins on the blood draw date and must be completed before arrival. The 180-day quarantine is the maximum detention period imposed on pets that arrive without meeting the requirements. One is a pre-travel obligation. The other is the penalty for not completing it.
All costs are at the importer's expense and vary depending on the facility, the length of detention, and the services required. Confirm current rates with AQS or your relocation coordinator before travel.
Yes. If you choose not to have your pet undergo detention quarantine, you can arrange to have them returned to the exporting country. All return procedures and costs are the importer's responsibility. Confirm requirements with the authorities in the receiving country before arranging any return.
