Shipping a Pet to Japan from Boston: How to Choose the Best Route

TLDR: JAL operates the only nonstop flight from Boston to Narita at approximately 14 hours. Connecting options via Seattle, Dallas, Chicago, Denver, and Houston are available through JAL and ANA. United no longer accepts general pet cargo. All flight selections must account for Japan's 5PM customs cutoff and any applicable seasonal breed embargoes before booking.

Shipping a pet to Japan from Boston involves one of the longer international pet cargo journeys available from the US East Coast. The only nonstop option is Japan Airlines (JAL), which operates daily flights from Boston Logan (BOS) to Narita (NRT) with a flight time of approximately 14 hours. If JAL is not the right fit for your move, connecting routes through other US hubs are available with different airline combinations. Here is what you need to know before booking. For full Japan import requirements, see our Japan pet import guide.

The Nonstop Option: JAL Boston to Narita

JAL is the only airline operating nonstop flights from Boston Logan (BOS) to Narita International Airport (NRT). Flights depart daily with a flight time of approximately 14 hours.

On JAL international flights, pets travel as checked baggage in the cargo hold. Pets are not permitted in the cabin on international JAL flights, with the exception of certified service dogs. JAL does not accept French Bulldogs or Bulldogs on any flights due to respiratory risk. Reservations for pets must be made in advance and cargo space is limited. Contact JAL directly to confirm availability on your specific flight. A letter of consent acknowledging the risks of air travel for pets is required at check-in. JAL recommends arriving at least 120 minutes before departure when traveling with a pet.

Connecting Route Options from Boston

If JAL does not work for your move, several connecting routing options are available from Boston through US domestic hubs: via Seattle with Alaska Airlines connecting to JAL, via Dallas with American Airlines connecting to JAL, via Chicago with American Airlines, and via Denver or Houston with United Airlines connecting to ANA.

United Airlines does not accept general pet cargo on its flights. Pets on United travel in-cabin only in an approved carrier under the seat, which is only suitable for small pets. The only cargo exception is for active duty US military on PCS orders and State Department Foreign Service Personnel traveling on assignment. Large dogs cannot travel as cargo on United-operated legs unless you qualify under those programs.

ANA accepts pets as checked baggage in the cargo hold on international flights. The fee for a routing between North America and Japan on ANA is USD 400 or JPY 40,000 per cage. The cage plus pet must not exceed 45kg total, and the sum of the three cage dimensions must not exceed 292cm. ANA requires an IATA-compliant hard crate. Reservations must be made by phone, as online booking is not available for pets on ANA.

Breed Restrictions and Seasonal Embargoes

ANA does not accept short-nosed (brachycephalic) dog breeds between May 1 and October 31 due to heat risk. The affected breeds include Bulldog, French Bulldog, Boxer, Shih Tzu, Boston Terrier, Bull Terrier, King Charles Spaniel, Tibetan Spaniel, Brussels Griffon, Chow Chow, Pug, Chin, and Pekingese.

JAL does not accept French Bulldogs or Bulldogs on any flights.

Domestic airlines in Japan do not accept snub-nosed breeds as cargo during summer months. Confirm current embargo dates and whether your breed is affected directly with your airline before booking.

If your pet is a brachycephalic breed, confirm acceptance directly with the airline before booking. Summer travel from Boston overlaps directly with both ANA's international embargo and the domestic Japanese airline embargo period.

The 5PM Arrival Rule

Book your flight to arrive at Narita before 5PM. Pets arriving in Japan after 5PM cannot be released from their crates until customs reopens the following day. A 14-hour nonstop from Boston departing at midday will arrive at Narita in the late afternoon Japan time. Confirm the local arrival time against the 5PM cutoff before booking.

What to Confirm Before Booking

Airline pet policies, route availability, and cargo acceptance rules change without notice. Before committing to any routing, confirm the airline accepts your pet's breed and crate size on each leg of the journey. Confirm cargo space is available, as space is limited and must be reserved in advance. Confirm the aircraft type operating each leg can accommodate your pet's crate dimensions. Confirm the local arrival time in Japan falls before 5PM. Confirm no seasonal breed embargoes apply to your travel dates.
