You don't need a Japanese postal address for Amazon JP. They will deliver to Lawson convenience stores, which are in Haneda T2/International, Kansai T1, and maybe Narita T1/2 (I don't remember). No ID required for pickup. You'll get an e-mail with a link once you pay. Show it to the clerk on your phone or print it out beforehand and they will scan it and get your package.

Ideally do this around a week before departure to allow for delivery time.
