What are the luggage allowances for flights to Japan?
For international flights, the luggage allowances change very frequently. It’s best to check with your airline. When you do, ask how long the allowances they give you are in effect.
You will also be allowed one carry-on that must fit under your airline seat. Keep in mind that you’ll need to manage all your luggage by yourself while in Japan. Having someone at home send belongings can be very expensive and is not recommended—you’ll only have to cart all that stuff back home. Try to pack only essentials, leaving enough room in your bags for gifts or souvenirs you’ll purchase in Japan.
