@wittmann:
Agreed. That NO could even replace the Strategic outer defensive perimeter(Guam, Midway etc.).
Conquering China is difficult and much effort is required; this would be the reward.
Yeah, and it is at least possible too. That 5 island NO is next to impossible. I have had games where Japan won on the Pacific board and still didn’t get that NO. The only time I have gotten it was when the Allies spent most of their resources in Europe and Japan was allowed to go hog wild.
