But you can often get around that restriction by addinig a small flight from your nearest neighbor to home. Shorts flights like YVR-SEA can be really handy to get around the return to originating country rule in the ANA program.

In a little more detail: ANA allows tickets of the form www-xxx, yyy-zzz as long as www and zzz are in the same country (and perhaps yyy-zzz is crossing a border). If you want a one-way, then book a nice long www-xxx segment and the shortest/cheapest yyy-zzz segment you can find.
