One of a great think about Award travel is that NW allows a free stop (one only) over at one of the International Gateway for your international itinerary. HNL is one of those gateways and you can spend a few days (or more), if you want. (Can't have a open-jaw and a stopover though).

Looking through availabilty for connecting itinerary all the way from KIX to your final destination might not be available otherwise. Breaking it up into pieces might be a better idea.
