This is quite a derail, but I thought I'd post it as a bit of history:

I remember that if you had a ticket that routed on one of these "domestic-international" flights (on NH/JL at least) but you immigrated at NRT, you could still fly NRT-KIX. The airline would issue you a "
domestic portion boarding pass" (国際区間搭乗票) that you'd show to immigration in lieu of a passport (since you still had to depart from the international section of the terminal). At check-in they'd write "CABO" on your boarding pass to denote that the airline was transporting you as cabotage (since NRT-KIX was technically an international route).
