Planning my trip to Japan and dug into the latest entry rules for 2026. Sharing what I found:

• Japan doesn't officially mandate an onward ticket by law, but airlines flying into Narita/Haneda are getting stricter — several carriers now require proof of departure before they'll even issue a boarding pass.
• The Visit Japan Web system now covers immigration, customs, AND tax-free shopping registration. Fill it out before you fly to breeze through.
• If you're on a tourist visa waiver, immigration may ask for a rough itinerary — having a flight reservation (even a cancellable one) helps a lot.

Anyone flown into Japan this year? Did the airline check your return flight?
