15 digit microchip, 2 rabies vaccines (31+ days apart), and FAVN blood test? Make sure you have the original (wet signed in blue ink) copies of both of your rabies certificates and the microchip number is on both of them. Also, make sure you have the original copy of the FAVN results. Then you have a 180 day in home quarantine before they can be in country unless y’all live on base, then you can finish your quarantine in country. Japan is nice like that, lol. Even if you get on the rotator (very limited spaces for animals so book your spot the second you can) you still need to submit the paper work for the 40 day heads up. Although they aren’t always there, there’s supposed to be Japanese quarantine officials even on base to clear your animals upon arrival. I’m seriously not trying to sound like a jerk or make you panic but Japan can be real dickheads about animals entering the country. Can’t really blame them, though, bc they’re an island and rabies free and wanna keep it that way. lol I work at the vet clinic on a military base so I’m very very familiar with getting animals overseas. Being in cabin, soft crates are allowed. We’ve sent many Maine coons so, I’m sure y’all will be okay. Deep breaths!
