The rules for taking your dog or cat on trains and the shinkansen, finding pet-friendly hotels, flying domestically, and what it all costs.
Japan is a surprisingly pet-aware country to travel in, but the rules are specific and not always intuitive. You generally cannot simply walk your dog onto a train on a leash, yet a small dog in a carrier rides for a few hundred yen. Hotels range from "no pets ever" to onsen ryokan that welcome them. This guide covers trains, the shinkansen, hotels, domestic flights, car rentals, and pet-sitting — with the costs and the Japanese vocabulary you will need.
On most Japanese railways, including JR, pets travel as 手回り品 (hand luggage), not as passengers. The core rules:
This effectively limits train travel to small dogs and cats. Larger dogs cannot ride ordinary trains, which is why big-breed owners rely on cars.
The bullet train follows the same carrier rule: small pet, in a carrier, kept inside the whole trip, with the hand-luggage fee. A practical tip many owners use is to reserve the last row of the car, where there is space behind the seats for the carrier and you disturb fewer people. Some operators have begun trialing dedicated pet-friendly cars or services on select routes; check the specific line before you travel, as availability changes.
Pet-friendly lodging (look for ペット可 or ペット同伴可, meaning pets may accompany you) is increasingly common. Expect a pet surcharge of roughly ¥3,000 to ¥10,000 per stay or per night, and read each property's rules on size, number, and where the pet is allowed (room only, or also common areas). A growing number of onsen ryokan now welcome pets, sometimes with private pet-friendly baths or rooms, though pets are virtually never allowed in shared hot-spring baths. Booking sites let you filter for pet-friendly stays.
For longer distances, domestic airlines carry pets — but mostly in the cargo hold, which carries real risk and stress:
Because cargo transport is stressful, many owners avoid flying pets unless necessary, especially for nervous animals or in summer.
A car is the most flexible way to travel with a larger dog, but many Japanese rental companies do not allow pets, or allow them only in a carrier and charge an extra cleaning fee. Search specifically for ペット可 レンタカー (pet-friendly rental cars) and confirm the conditions when booking. Bring a seat cover and keep the car clean to avoid cleaning charges at return.
Sometimes the easiest "travel with your pet" plan is not to. If you are taking a trip where a pet cannot come, the two main options are:
The single most important item is a proper carrier, since every form of public transport in Japan requires one. An airline-and-train-appropriate pet carrier (ペットキャリー) that meets the under-10kg dimension rules is the foundation of any trip. Also useful: a collapsible travel water bowl (携帯水おう) for hydration on long journeys, and a portable pet bed (携帯ベッド) to give your pet a familiar spot in an unfamiliar hotel room.
Travel is an occasional cost, but it adds up — carrier, surcharges, pet hotels — alongside everything else. See how it fits the bigger picture with our Pet Cost Calculator and the first-year cost checklist.

Train rules reflect JR and major private railway hand-luggage (手回り品) policies for pets; confirm specifics with the operator before travel.
Airline policies (ANA, JAL, StarFlyer) and seasonal restrictions change — always check the carrier's current pet-transport rules.
Fees and surcharges are typical ranges and vary by provider, route, and season.
