Pet Transport Mexico to Japan: 2026 AQS Guide

When families who have previously moved pets to Europe encounter the Japan AQS requirements, the immediate reaction is often surprise at the difference in scope. The EU process requires one vaccination and a titre test, with a 90-day wait. Japan requires two vaccinations with a gap between them, a titre test at a specifically designated laboratory (not just any approved lab), a 180-day wait, and a mandatory advance notification 40 days before arrival. That is a substantially larger undertaking.

The reason is straightforward: Japan has been rabies-free since 1957. The AQS takes every possible measure to prevent reintroduction of the disease. For non-listed countries like Mexico, where rabies is endemic, the full protocol applies without exception.

Mexico is a non-listed country for Japan AQS purposes, meaning the most demanding import pathway applies. The two-vaccination requirement (first and second vaccination at least 30 days apart) is specific to Japan. After the second vaccination, you wait another 30 days, then draw blood for the titre test. The blood must go to an AQS-designated lab. Japan publishes its approved laboratory list on the AQS website (maff.go.jp); in Mexico, confirm which labs are currently on the list before drawing blood.

Once the satisfactory titre result is in (0.5 IU/ml or above), the 180-day wait begins from the blood draw date. Travel before this date and your pet faces quarantine at the AQS facility for the remaining days. The 40-day advance notification must be submitted through the formal AQS pre-registration system well before your travel date.

Aeromexico operates a direct MEX-NRT (Mexico City to Tokyo Narita) service, which simplifies the cargo routing compared to many other Latin American origins. A direct flight means fewer handling events for your pet and a clearer chain of custody for the documentation package.

Aeromexico Cargo accepts live animals with the full AQS documentation package. Confirm with their cargo desk that live animals are accepted on the specific MEX-NRT service for your pet’s dimensions and weight. Some aircraft configurations on the route have limited hold space for large crates.

Japan Airlines (JAL) and ANA also serve MEX-NRT, in some cases via US hubs. JAL Cargo is particularly experienced with AQS documentation requirements for Mexico-origin pets, as there is a significant Japan-Mexico business and expatriate community.

Cargo costs from MEX to NRT typically run USD 1,400-3,000. The trans-Pacific flight is long: approximately 14 hours direct. Your pet travels in the pressurised hold throughout. IATA-approved crates are mandatory, and the crate must give your pet room to stand, turn, and lie down naturally.

On arrival at Narita (or Haneda), your pet is transferred to the AQS inspection facility. This is a government-run animal inspection centre separate from the main airport terminal. The facility has kennels for dogs and separate areas for cats.

For a Mexican-origin pet with all documentation correct and the 180-day wait confirmed complete, the minimum inspection period is approximately 12 hours. During this time, AQS vets check the microchip number against all records, verify each step in the vaccination and titre test sequence, confirm the dates, and conduct a health inspection of the animal.

Once the inspection is complete and everything is confirmed in order, your pet is released and can be collected from the facility. Your transport agent’s Japan partner handles the coordination with the AQS facility and the collection logistics.

If any documentation error is found during the inspection, or if the 180-day count is found to be incomplete, your pet’s stay at the facility extends to cover the remaining wait period. The facility is functional: your pet will be fed, watered, and monitored, but it is not a comfortable home environment. Getting the documentation right before departure is everything on this route.
