NRT, HND, KIX, and NGO has international – international transfer point. I am not sure if other airports in Japan has international – international transfer. Anyway, at NRT, HND, KIX, and NGO all need to show is printed itinerary showing onward international flight from that airport.
Every single day there are international transit passengers who arrive without a boarding pass for connecting flights; connecting airlines not serving origin airport, departing airline could not print connecting boarding pass (not in same alliance), could not do online check-in (verification of visa required, etc.), could not print boarding pass (not all countries have same online access to average people like in western Europe, Japan, or the U.S.).
International transit passengers arriving without a boarding pass for connecting flight is quite common situation. You will find at other forums at FlyerTalk many actual experiences indicating all needed was printed itinerary and do not have to have a boarding pass.
