The short version
- Japan's dog/cat import rules run on a rabies antibody titer test plus a 180-day wait afterward — the clock that actually determines your earliest arrival date, and it can mean starting preparation up to 7 months out.
- An advance notification to Japan's Animal Quarantine Service is required at least 40 days before you land, separate from the titer test timeline.
- Miss a requirement and the quarantine authority can hold your animal at an animal quarantine facility for up to 180 days on arrival — check your specific country/region and animal with the Animal Quarantine Service (AQS) directly, since conditions differ.
- Pet-friendly rental housing is a minority of the market (roughly 1–2 in 10 listings), and cats or small dogs are approved far more often than medium or large dogs.
- Pet-friendly units commonly add roughly half a month to a full month's rent to the deposit on top of the usual move-in costs.
A relocation offer with a start date attached is also, quietly, a deadline for your dog's blood test. Japan's animal import rules don't care when your flight is booked — they care when a lab confirmed your pet's rabies antibody level, because a mandatory wait starts from that date, not from your travel date. Get the order wrong and the trip that was supposed to happen in three months turns into one that can't happen for seven. This guide works backward from your target arrival date through the quarantine steps, then forward into the part nobody mentions until you've landed: how hard it actually is to find a pet-friendly apartment once your dog or cat is finally here.
The clock that actually controls your timeline
Japan's Animal Quarantine Service (動物検疫所, AQS), under the Ministry of Agriculture, Forestry and Fisheries (MAFF), sets the import requirements for dogs and cats from most countries. The steps, in the order they generally need to happen:
- Microchip implantation that meets the required standard, done before the next two steps — a rabies vaccination or blood draw performed before microchipping generally doesn't count.
- Two rabies vaccinations, spaced at least 30 days apart, given after the microchip is in place.
- A rabies antibody titer test, drawn at least 180 days before your planned arrival, showing a result of at least 0.5 IU/ml at a laboratory designated for this purpose. This blood draw date — not your booking date, not your visa date — is what starts the 180-day countdown.
- A waiting period of 180 days after that blood draw before your animal can enter Japan.
- An advance notification to the Animal Quarantine Service at least 40 days before arrival, confirming the flight and import details.
Line those up and the realistic lead time is closer to seven months than the six you'd get from the 180-day wait alone, once you account for the two spaced-out vaccinations that have to happen before the titer test can even be drawn. If your dog or cat is already up to date on rabies vaccinations and microchipped, you may be able to move straight to the titer test — but confirm the vaccination sequence still satisfies AQS's specific order-of-operations requirement before assuming any past vaccination counts.
Working backward from a target arrival date
| Step | Roughly when, counting back from arrival |
|---|---|
| Microchip + first rabies shot | ~7+ months before |
| Second rabies shot (30+ days after the first) | ~6.5 months before |
| Titer test blood draw (≥0.5 IU/ml) | Exactly 180 days before arrival, at the latest |
| Advance notification to AQS | At least 40 days before arrival |
| Arrival in Japan | 180+ days after the titer blood draw |
General sequence only. Exact requirements (designated laboratories, accepted vaccine types, and whether your departure country needs additional steps) vary by country and region of origin — confirm your specific case directly with AQS before you schedule anything.
If the timeline doesn't line up
An animal that arrives without meeting the requirements above doesn't simply get refused entry and sent back on the next flight. Japan's import rules describe a quarantine hold at a designated animal quarantine facility, and the maximum length associated with an incomplete case runs as long as 180 days — effectively the same wait you'd have avoided by preparing in advance, except your animal spends it in a kennel instead of with you. The exact outcome depends on which specific requirement is unmet and your country of departure, so this is a case where calling AQS before you book flights is worth more than any guide. We are not a substitute for confirming your exact requirements with the Animal Quarantine Service.
Once you land: pet-friendly housing is the minority option
Assume, going in, that most rental listings in Japan are not pet permitted (ペット可, petto-ka). Real estate industry write-ups covering the Tokyo market put pet-friendly units at roughly 10–20% of listings overall, with a clear tilt by animal:
- Cats and small dogs, generally cited around the 5–10 kg range and under, get approved far more often than larger animals.
- Medium and large dogs are the hardest case. Approval outside a low-rise building or a detached house is uncommon, and some buildings that otherwise allow pets still draw the line at dog size or breed.
Where a unit does allow pets, budget for a real cost difference, not just a smaller pool of listings: an additional deposit on top of the standard shikikin is common, commonly cited in the range of roughly half a month to a full month's rent extra. Ask specifically whether that additional amount is refundable, since practice varies by landlord.
Where this connects to the rest of your housing search
Pet ownership narrows an already complicated search, so it's worth reading this alongside the wider decision rather than as a standalone problem. Our guide to choosing where to live in Japan compares share houses, regular apartments, monthly flats, and guest houses by the things that block foreign renters generally — pet policy is simply one more filter on top of that. If a regular apartment fits, the guarantor-company screening covered in our guide to Japan's rental guarantor system still applies in full; a pet doesn't change which company reviews your application, though it can change which properties are even willing to submit it.
Some share-house operators do allow pets on a per-property basis rather than as a blanket policy, so it's worth asking directly rather than assuming a share house is automatically off the table — but treat any individual "pet friendly" listing as unconfirmed until you've verified it for the specific room, not the operator as a whole. Neither of the two share-house operators we cover in our housing comparison guide should be assumed to be pet-friendly by default; ask before you apply.
What this guide does not cover
This is general orientation on the shape of the process, not a substitute for AQS's own country-specific requirements or veterinary advice about your specific animal's vaccination history and health. Designated laboratories, accepted vaccine brands, and additional steps for animals from certain countries or regions are AQS's call, not ours, and rules can change. It also doesn't cover species other than dogs and cats, which follow different import rules entirely.
