Japan Airlines does not accept dogs in the cabin, which is exactly the sort of detail I wish airlines printed in bold. Dogs travel in cargo or the hold instead, so Luna's carry-on strategy would not translate here. I compared this policy line by line, and the split between cabin and cargo is the first thing worth pinning down before anyone books a single leg.

Japan Airlines's pet policy splits into cabin and cargo. This page summarizes the weight limits, fees, brachycephalic-breed restrictions, and carrier specifications for both modes — sourced from the airline's official pet pages.

Japan Airlines will not transport dogs or cats under eight weeks, counted as 56 days from birth. Confirm the puppy passes the 56-day mark before the travel date, not before booking. Ask the vet to note the exact date of birth on paperwork. A dog just under the threshold on departure day gets refused at check-in.
Japan Airlines restricts brachycephalic, snub-nosed dog breeds because they tolerate high temperatures poorly. Check whether the breed appears on the snub-nosed list before committing to cargo. Confirm current restriction status directly with the airline, since seasonal temperature rules can tighten it. Arrange an alternative route or transport method for any breed that falls under this restriction.
One policy line rarely tells the whole story, which is why I always cross-check against the exact route and dates. Luna disapproves of taxiing, but she approves of preparation, and so do I. Build a personalized plan with Pawgo's plan-builder for your specific trip, and you will get the cabin, cargo, and paperwork requirements laid out for your dog and your itinerary.
